Sorry. I can't send too much information such as drawing on the hubs here, 6 bearings, 2 front and 4 rear, normal bearings made in China/TPI /NBK/ S&S steel bearings, TPI/NBK/S&S ceramic bearings optional, normally we use TPI or S&S ceramic bearings. The carbon spokes we use are exactly same as some big brands use to build on their wheelsets.

I'm interested in a set of the CS-D50CU-28WV rims on DT240 hubs, CX-Ray spokes. Feel free to shoot me a message
-
Can D50CU-28 be made in rim brake version, 9x100 front 10x135 rear Bitex hubs, bladed spokes -
-
I assume the carbon spokes are STREN? How wide and thick are they? How do they lock into the hub? Threaded like CRW and Newmen, straightpull through the hub like dt swiss hubs, or inserted from the side like Winspace, Elite, Cadex, etc.

I had the same issue before; the pictures were too large. You need to resize them and save for web use. You can easily do this with online converter, same format just save for web and that will reduce the size in MB. After that you can upload the pictures.

here the pics
Thanks. I was wondering what that pattern entails. No offence to you or Peter but holy sh*t this looks hideous. Think I am gonna stick to non eagle wing pattern wheels.

Indeed, that doesn't make any sense, why we did that is some clients want different looking from others. And to my factory, we can register some appearance patent, we might get some favorable policy if we get more and more patents here in China.
-
I understand you mainly sell wheels, but do you sell carbon TT bars as well?
Thanks
-
Jeeez, this pattern is indeed atrocious! that's funny! And slower, too, for good measure. And heavier. I love it. Worse in every way.

The eagle wing pattern looks like something the cycling crazy president of Turkmenistan would request.

Ordered a pair of 65mm wheels for a future aero build. 26mm internal width look interesting. One of the few I've seen offered in 50 and 65mm depth. Peter offerd a "paint-less" finish which I didn't know was a thing. Anyone has any experience?

Used 25mm MucOff tape on my CS 26mm IW wheels which allowed tool free installation for Schwalbe Pro One tires that hold pressure very well after seating with compressed air.

If it's experience with Peter, i bought 5 wheelsets from him. We're all very happy with them, been flawless. they're on my tractor, so i ride mine several times per week.
In terms of finish, matte black is the default finish, and the lightest. i guess this no paint finish here might save a few more grams? But in general, you dont want gloss, nor funky carbon patterns because gloss is heavier, and fancy carbon patterns are just there to look fancy, so it just adds weight.
Looks cool. Next time i order wheels i'll ask the question.

Hello, I am interested in CS-D50CU-33 wheelset.
-Where can I learn more about availability of hub & spoke options? Probably DT240 & CX-Ray but would like to understand pricing for other options.
-Interested in your spoke drill & assembly QA/tolerances and lacing also. (e.g. CNC drilled?)
-Also interested in surface finish options - would ideally like satin and unpainted ("paint-less") depending on the carbon finish but can also do matte black.
-Interested in pricing and assembled mass/weight.
Thank you in advance!
P.S. I'm motivated to upgrade my wheels but I'm also new here - if someone sees an opportunity to educate me or suggest better choices I'd appreciate it.

Thanks for your inquiry. I think I should just have replied your message on WhatsApp.

I went for their own in-house hubs and pillar 1420 spokes. According to Peter they should come up at around 1520g which is not the lightest but considering the price, depth, and width of the rims, I think it's excellent.
I'm planning to use 30c tires which will probably end up much wider

I just ordered a pair of wheels from peter with the following specs:
D40CU-33 rims T800 version 24/24H UD Matt with assembly holes in the rim bead.
Carbon Speed custom hubs 36T rachets center lock straight pull for 100*12/142*12 with Shimano driver
Pillar 1420 spokes
Pillar aluminum nipples
Will report back when i receive them.
Until now it was a great pleasure communicating with peter. Fast, friendly and very responsive.

to be fair it's very easy to get quotes from Peter, but typically a wheelset with house hubs and steel spokes will be in the 500$ range, and with carbon spokes in the 700 range. If you want branded hubs it adds to the cost. But i agree it wouldnt hurt to know about pricing when people post their builds.

With the 10 year discount action I paid 435 USD/pair plus 110 USD shipping incl. prepaid taxes, so 545 USD in total.

I understand that it’s really easy to get quotes from Peter, but that immediately removes the pricing from public and put it into a private conversation. I think the better way for him to go about this is when Peter makes the post he should list the cheapest build cost and the most expensive build cost so people can at least see the price range for his products. If he was more upfront about pricing by putting a price range instead of saying email me or WhatsApp me, I think it would drive more interest because consumers could see on the front end what they might pay.

I agree. Also judging by what has been mentioned, are those prices really good v/s what you can do on Aliexpress with brands like Go-zone, CSC, Elite and many others? I guess I'm trying to understand the hassle of chatting on WhatsApp or email and placing an order when you can get 1300 grams 50mm deep wheelsets for same price on Aliexpress sometimes with free shipping even.
-
Thank you guys for your suggestions. Why I didn't want to list pricing here when I created this thread there are quite a few some other Chinese companies posting and viewing every day here on this public forum. And people are looking for different options.
I modified my 1st post with price range just now. However we don't sell anything on Aliexpress, we don't think it is worthy of time to explain quality or price difference between our products and theirs, for example, many guys mistake our company for CSC(Carbon Speed Cycle), that causes we need to say full company name to others every time, and some sellers on Aliexpress they are just resellers without bottom line and they don't keep their words to offer after-sale service but they would decrease their pricing again and again to sell items. I am not saying all sellers or stuff on Aliexpress are not good, just saying that we don't want to sell products there. As manufacturer we attend to the bicycle fair like Interbike or Eurobike show so we got numbers of OEM clients to cooperate with, some of them are name brands. Our pricing varies depending on many factors and is constantly evolving, but QUALITY and SERVICE are the most important as always , old members here know our company very well, and we offer wheelsets at almost price points. We can provide an indicative quote very quickly via WhatsApp or email, so please don't hesitate to get in touch. Thank you guys.

I'm intereset in the 33mm wide rims.
Does anybody know how a 30mm GP5000 will sit with these 26mm inner width rims? Will it be around 33mm?
-
Just wanted to follow up and say I had a really great conversation with Peter about how going forward he can share a little bit more pricing in his posts so we as consumers can more easily make purchasing decisions. After my conversation with him, I do believe he probably has some of the best customer service of all the vendors on this forum and in the future, my next pair of wheels will be purchased from him.

I just received my wheels, and put gp 5000 s tr 30 on them, and they sit really in line with the rim.
I can provide measurements and pic tonight(~8h)

Okay so as promised, pic of wheels with also a short review.
I bought the wheels because of Serge's propaganda
I haven't tried them yet bc I'm still missing some parts (aliexpress in france sucks)
Wheels are carbon speed own hub, looks like every other ratchet hub, 1420 pillar spokes, and 50x33 rim
weight is 1371g. Note that rim tape and valves are not included.
GP 5K S TR 30 are 33mm wide, so they fit perfectly, and follow the rim nicely.
Hub is really loud, but I feel like there is also no grease, so I bought dt swiss ratchet grease to try.
Decals cost 30 euros, thanks to a price reduction from Peter.
Bought them 23/08, arrived 27/09.
Buying experience was really nice, peter was really helpful, and gave me advices on what to buy. He also made the decals himself based on a bad photoshop that I did.
I will make another review once I've done around 200km with them

I recently came across this post when searching for some gravel wheels and decided to email Peter. Gave him an idea of what I wanted and he emailed me back within a few days with some different options for a custom build. Went with the 40mm deep 26mm inner and 34mm outer, model no. CS-D40CU-33 built with house hubs (ratchet style), 24 Sapim cx-ray spokes and Shimano freehub. Went with no holes in the rim bed for easy tubeless setup and was looking for a sub 1400 gram wheelset. Within about 10 days I received pics of the hoops along with their weight, and within 14 days received pics of the final build along with actual weight of 1349 grams. Received the wheels about 2 weeks later so about a month from the initial order being placed. Setup went easy and I really put them through hell last week on a gravel ride in Vermont and they're still spinning true. Very happy with the purchase and communication from Peter throughout the process. Highly recommended.

That's looking real nice! Lovin' that gravel ride and look. I can't tell with your attached image, but with the 34mm outer width of the rim, what width tire did you put on? I see it's Schwalbe G-ONE branded, but can't tell from the markings your chosen width. And how did it feel at that width?

The tires are still the stock Schwalbe G-One Bites in 45c that came on the bike. I was running 35psi in the stock wheels for pavement rides and 30psi offroad. These wheels are definitely firmer at the same pressure so I need to play around with lower pressures. The tires are ok offroad but I'd like to switch to something like a 42 pathfinder or 45 g-one rs for a little more speed on the road. In my area I end up covering a lot of road between gravel/dirt sections and I'll likely be using this as my road bike this winter.

Just received pictures of my wheelset from Peter. Turned out lighter than expected. Paintless finish looks sick
-
I asked for a quote for a wheelset to compare to the lightbicycle falcon pro turbo wheelset.
I'm torn whether i want some dt wiss 240 or knock off hubs. Are the xmcs in house hubs compatible with dt swiss replacement parts? I would hate to have to realce a new hub, if anything fails.
Edit: Already got a reply from Peter and all i can say is wow, that is some value offered, i will glady chose xiamencarbonspeed.

I own a couple of noname Chinese hubs. A set from lightcarbon and r13 from Yuanan. you can use regular ratchet kits from aliexpress or dt swiss, they work perfectly fine. bearings are standard 6902, 6802. My only concern is trying to find a compatible freehub body if you need one

Did you consider carbon spokes for these wheels?
Also, does anyone know how the aerodynamics are affected by conventional steel, or carbon spokes? Bladed in either case, of course, and I realise there are a lot of different carbon spokes.

I didn't. There's no benefit for me from going with carbon spokes. Maybe a few grams here and there but steel spoke wheels are much easier to service. I can replace the spokes or hubs at any time without any problems. If I break a carbon spoke I have to order it from China. Carbon spokes require a different hub as well, which I doubt you can source easily.

Thanks, I do think you can use some carbon spokes with standard hubs but I may be mistaking.
In any case I hope you get to test the wheels out and report back, I might copy the setup for my Venge (2020 model).

My friend crashed one of Peter's wheels, and broke 4 steel (Pillar wing 20) spokes. I didn't have enough spares to repair it (from memory, the wheelset uses 3 different lengths, so the moment you break more than 1, the probability you have inventory goes down dramatically), and good luck sourcing these spokes outside of china at a good price. I guess i should have called wheel builders, now that i think of it, but even then, i bought rims without holes in the rim bed for easier tubeless setup and maximum strength, and i didn't want to spend 1 day repairing it. So, i bought a replacement wheel from Peter, ordered the missing spokes from him, and my friend got the 1st wheel repaired by his LBS, so now he can happily crash again and already has a spare :D
So... if the hub isn't some weird ass bonded thing, and if you have spare carbon spokes of the right length, i dont think it makes a huge difference in terms of repair-ability.
One key difference is stiffness though, if you run a beefy aero bike, with carbon spoked wheels, with 25mm tyres at 110psi, on bad tarmac, wear a mouth guard as your teeth will rattle. If you run wide tyres, tubeless, then if you ride on good enough roads, carbon spokes are probably a good idea if you care about performance. The price difference is decreasing, Peter typically quotes a good set of steel spoked wheels for ~500 and ~700 for carbon, so given that everything is expensive now, 200 bucks amortized over the life span of your bike, if not 2 or 3 bikes, seems pretty reasonable.
I wonder if aliexpress sells spare spokes. i dont think i looked there either, now that i think of it. it'd make a ton of sense, they have such good agreements with shipping companies that you could probably source spares on demand easily. Aliexpress, now that it works flawlessly, pretty much, has transformed the way i source and build bikes. Can't understate the convenience of ordering exactly what you need when you need it, as opposed to over ordering stuff from china (Alibaba & the likes) and shipping large boxes.
As to ride quality, i've bought 5 wheelsets from him, and we're all happy with them. A whole season on them, no issues. Peter seems to be very reliable OEM, and also, wheels are now so commoditized that as long as you order the right stuff from a reputable seller, i really dont see why you'd be disappointed. Peter lets you custom build anything, his pricing is competitive, and he doesnt force you to put logos on the wheels. For example, certain models from Elite are nice (although mostly their rims are too narrow), but i refuse to have my bikes look like Xmas trees covered in logos, unless they pay me, i'm not showing their logo.

Guys. We are going to release our T1100 rims next week. The rim in attached pictures is D50CU-33 T1100 rim UD paintless finish, under 390g/piece.
We are going to build these rims with carbon spokes and our hubs. The promotion price for below combo wheels would be 635 USD/pair excluding shipping, lasts Dec 24 :
D50CU-33 T1100 rims 21/21H UD paintless
Carbon Speed hubs 54T rachets TPI ceramic bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
Carbon spokes with nipples
The weight for this combo wheelset would be around 1245g/pair
And we are doing 20/20H version lighter hubs which won't be released until 2025, it will save another 40-45g on the wheels by then.
-
I might be interested in the lighter hubs version 65mm deep. Do you know yet roughly in which part of 2025 it might be?

I am also looking for wheels right now, and depending on the design, these may also interest me. Do you have a rim weight for the 65mm deep T1100 rims?
Regarding hubs, do you build with 0011 / THR Industries RX hubs or R3 road hubs? With CX-Rays Super or Alpina Hyperlight Aero spokes, these appear to be built wheels lighter than most carbon-spoked wheels.

Pillar Wing 20 are virtually identical with Sapim CX Ray, DT Swiss Aerolite and CN Spokes Mac Aero 494. I've built wheels with all of them. And you can definitely replace one with the other. All wheelsets use different length spokes - carbon or not. So that's not really an argument for one over the other.

Peter, are you guys gonna have a similar version for MTB wheels?
-
Knowing you can mix and match safely is above my pay grade (and I doubt manufacturers would agree with you). I wouldn't want to pretend I understand the physics of spokes and if my friend is going at 100kmh downhill, I wouldn't want to worry whether the melting pot of spokes from the bin is going to hold or not.
Where do you source your spokes? Are there useful resources I missed? My googling skills led me nowhere back then.
I'm not saying you should just put any old spoke into your friends wheel. I'm saying they are exactly the same.
Sapim in Belgium came up with the CX-Ray spoke by drawing a round spoke to a cross section of 0.9mm x 2.2mm. Everyone else subsequently came up with an exact copy of that design. The cross section doesn't differ with any of the other ones because this is exactly the biggest aero spoke that will still fit through conventional holes in any given hub.
So all of the spokes I mentioned are steel spokes with the same cross section. Therefore they have the same elasticity, regardless of differences in the grade of the steel (Sapim, I guess, might use higher grade steel than CN spokes. But that's really only a guess). There might be the tiniest differences in the length of the bladed section but if you'd bring a wheel to me I wouldn't hesitate replacing a Pillar Wing 20 with a CX-Ray. There will be no difference, I assure you.
Being in Europe, I get my spokes from wheel-parts.shop in the Netherlands. I never really bother replacing Wing20s like for like (unless somebody demands it) since there is a distributor in Germany getting them from Taiwan, but they end up being more expensive than Sapim. I happily buy chinese wheelsets with Wing20s however, as I don't think the up in price to upgrade to CX-Rays does anything. If I want to go cheap, I buy CN spokes which can be had in Germany. The threads on these are sometimes not rolled that well which is annoying when building wheels.

Are you also offering Wheels with Dynamo?

Yes, we will do, it would be 29er 30mm inner width XC rim around 300g/piece

I might be interested in the lighter hubs version 65mm deep. Do you know yet roughly in which part of 2025 it might be?
I don't think we want to do the T1100 version on D65CU-33 rims for now, it is too deep and we need to assess the possibilities like balance between strength, stiffness and light weight. We will try to do T1100 and test on D65CU-33, if everything is okay, then we will release them too.

Are you also offering Wheels with Dynamo?
Sorry, no for now.

And 58-60mm ?

Pillar Wing 20 are virtually identical with Sapim CX Ray, DT Swiss Aerolite and CN Spokes Mac Aero 494. I've built wheels with all of them. And you can definitely replace one with the other. All wheelsets use different length spokes - carbon or not. So that's not really an argument for one over the other.
Wing 20's are .3 mm thicker and shallower than aerolite I and cx ray. Wing 20 will be measurably slower aerodynamically. Aero 494 are completely different and much closer to dt Aero II than any of these other ones so I'm going to assume you meant the 424 which are very similar to cx-ray and aerolite I

Thanks for clarifying. And yes, I meant the 424 then. I can never remember the number codes with CN spokes.

Hi everyone,
As I'm a bit green in the topic, I have a question. What considerations should one have in deciding between the T800 (regular) version of the rim, versus the new T1100 which Peter mentioned they're releasing this week?
It's surely nice to shave some grams off, but other than the weight aspect, should I expect a difference in riding experience or, most importantly, durability? What's your take on this new, lighter rim, paired with steel spokes?

T1100 is T300 faster than T800

Any plans on releasing new frames gravel or road?
Also possibly ship groupsets together with the packaging?
For me this this is a game changer to be able to get them shipped all together and save some costs. I understand it's not part of the core business (at least the groupsets) but at least for me, sourcing "all bigger pieces" - frame, groupset, wheels - from 1 place would help me definitely to choose a supplier. So far only Tantan is providing this to me, but their prices on groupsets are too high and wheels manufacturing needs thruiing most of the times.

It depends so much on the layup that you can't make any conclusions or even serious assumptions from material alone
-

And I doubt that the rim is full T1100. Maybe a mix of 700, 800 and 1100.
-

It can't be full t1100, it wouldn't pass impact résistance test. The T1100 version is a mix of all 3 fibers.
Correct. It can't be full T1100, otherwise it would be too fragile.

Thanks for the insights Serge. I decided to order the 50 deep, 33 wide rim with house bearings and pillar 1420 spokes. Peter has been quick to reply to my questions on WhatsApp. I’ll post an update after receiving the wheels.

We would release two new road disc frames, but biggest sizes on both framesets is about 54cm for now, and we are still having someone testing them.
I don't think we would offer groupset, it is not cost-effective to buy Shimano or Sram from China, and we don't want to be reseller on Ltwoo or Wheeltop, and their quality...
TanTan makes good quality frames, and we have been cooperating with each other on some points. Will try our best to offer best value frameset and wheels package.

The official tire is 700x32c but do you think a 35mm wide tire would fit? I like a narrow all road/gravel (very low knobs) tire and the other specs of this frame is exactly what I am looking for.

Could you send me an email? I will send you extra information for reference, I am not sure 35mm wide tires would fit or not, to me, i think it should fit with the frame.

Received my wheels from Peter last week. Could not try them yet as my frame hasn’t arrived yet. Did check them out and they look really good.
For this price point also seriously impressed with the weight. Just a few grams above 1400g. That is quite impressive for a 50mm deep set, 28mm iw and 36mm ew.
Communicating etc with Peter is top notch. Happy purchase so far ^^.

Consider wheelsets with CS-D65CU-33, but worried about 26mm internal. I bought lot of 25mm Schwalbe pro race (good deal 27$/piece) and want still used them. On my actual 21mm internal rims they have 26mm, I thing on 23mm it will be something like 27mm. So I suppose that on this 26 internal rim the tire will have something like 28-29mm. Question is, will it work and is it safe?

This combination of rim width and tire width is not recommended and likely not safe to ride.
Another thing: Peter, I sent a mail with a request a couple of days ago, and didn't get a reply so far. Does it simply take a bit longer or is it possible that my mail was lost?

It's already not a good idea because you will be cornering on the sidewalls with that combo

Sounds like you bought nice wheels for your previous Lada and now you're desperate to use them on your new Mercedes. Sell them for $25 per piece and move on.

I am planning go to 28mm tire, but in theese dayes, when you buy 28mm tire produced this/last years, manufacturers do not count that you have 26mm internal rim and theese tires are in the end 32-33mm wide - this is for me too big jump and bike life change from my actual 25mm. :)
-
28 mm is not a good idea either, that is still well outside ETRTO spec (https://www.schwalbe.com/media/f5/9b/3e/1716878352/Reifen_Felgenkombination_ETRTO_EN_(2).pdf). 26 mm inner width is for 35+ mm gravel tires. 30 mm is already questionable, but 28 mm? no way.

The craft racing works 5060 has a 25mm internal rim in the front and they recommend "above 26c for the front tire". I assume 28c on a 26mm rim would be fine but I wouldnt just because I think on these particular rims a 30/32c would be better in every way.
-
ETRTO actually went back in the 2024 spec and now requires 29+ mm tires on 25 mm rims. Pretty sure because combinations like 28 mm tires on 25 mm rims turned out to be problematic. There were some incidents, at least one in the pro peloton as well.

Hey Peter! Looking good, when you plan to release it? Does second frame follows similar, endurance-focused design, or is it more racy?

Pointless rule when there is no standard for measurent. Some 28c labeled tyres measure 30 mm on a certain rim while others measure 29 mm and anothed still might measure 32 mm. Now that manufacturers are catching up to modern trend we're getting new tyres that are labeled the same width as older ones when in reality they're actually notably smaller. But because the number on the label is the same ppl will happily run tyres that they would have previously considered 'incompatible'.

Guys. We are going to release our T1100 rims next week. The rim in attached pictures is D50CU-33 T1100 rim UD paintless finish, under 390g/piece.
We are going to build these rims with carbon spokes and our hubs. The promotion price for below combo wheels would be 635 USD/pair excluding shipping, lasts Dec 24 :
D50CU-33 T1100 rims 21/21H UD paintless
Carbon Speed hubs 54T rachets TPI ceramic bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
Carbon spokes with nipples
The weight for this combo wheelset would be around 1245g/pair
And we are doing 20/20H version lighter hubs which won't be released until 2025, it will save another 40-45g on the wheels by then.
Hello @PeterXu,
Are the D50CU-33 T1100 rims available already?
-
Yes. they could be customized now.
excellent.
Im intersted to know more on/order D50CU-33 T1100 disc in matte.
I have TCR 2021 and Seraph TT912 which can clear my Parcours Chrono 77/86custom (kinda wide).
-
Finally got my hands on the wheelset and so far I'm happy with it. 65mm rim with 26mm internal with in-house hubs and pillar 1420 spokes weight just under 1500g. The paintless finish looks fantastic. 30mm Schwalbe Pro one measures around 33mm and sits flush with the rim
-
Sorry about this, not sure why I broke this page, I didn't mean to, maybe I was trying to upload pictures. How to fix this?
I doubt you broke anything. Poor script writing for the website would be my guess.
-
page 8 is dead
the wheels are too light to be on a page ;D

What was the Price for this ?

What was the Price for this ?
I got the same spec as him I believe and received the wheels yesterday was $570 shipped to usa and paypal fees.
These are such a nice wheel spec wide, deep and light for the depth and at a good price. I'll probably get some of the D50-36 for my next bike. I was worried about the freehub noise but its not terrible, ali elite wheels hubs I've used are worse.
Peter are you going to do T1100 version of the D50-36?

Peter are you going to do T1100 version of the D50-36?
Yes, your wheels are exactly same spec, the only difference is your rims are in matt finish while Pavlo.k's are UD paintless, so your wheels are a bit heavier than his.
Yes, I think we ware going to do T1100 version of the D50CU-36 rims too.

Yes, you can use the DT rachets and spring washer to replace the original ones on our in-house hubs, beasings too. We just upgrade the bearings on in-house hubs with ENDURO steel bearings today, previous ones are NBK bearings, some clients don't like the NBK ones.

sup guys.
im interested with the d50cu-33 t1100.
i have been running parcours 28mm width with 32mm gp4season clincher on my tri bike(blue) just fine with 4mm clearance of chainstay (the tire is bulbous).
today i tried to fit on my tcr 2021(green:; have not ridden since new yr as im 100% on tt912) n found out the tire touching the chainstay.
im planning to make my tcr a touring bike.
do you think d50cu-33 with 30mm a no go on tcr?
edit:
to those of you having fitted 28mm Gp5k/Pzero 4s clinchers, what width does the tire stretched to?
Schwalbe 30mm seems to go 33mm per recent poster.
i plan to stay tubes
parcours: 22.5mm iw, 28mm ew

The front hub bearings are 63802 (15x24x7). The rear hub bearings are 63802 (15x24x7). The freehub has 1-63802(15x24x7) and 1-15267(15x26x7).

Received wheel set from Peter earlier this week. As expected, Peter has been super helpful and responsive.
Details:
Front D50CU-28 T800 rim 21H Rear D55CU-28 T800 rim 21H UD matt
Carbon Speed Custom hubs for carbon spokes 36T rachets steel bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
5.2mm carbon spokes
Roughly 1340 grams before I mounted tires, discs, cassette.
They look great...hopefully I'll be able take them out for a spin sometime soon.

@toxin Peter showed me a picture of the 20h hub. It's 294g/set and slotted straight pull, not side entry.
The updated wheels will be nice when they are released. The only drawback I see is that, according to many manufacturers' charts, 26mm internal width needs a wider road tire than most people would want to run. I think I would feel comfortable with 32mm on those wheels, following the rough ETRTO guidance, but that's at odds with the charts from Conti and Schwalbe.
-
im still undecided between d50cu-33 t800 or t1100 version, but im planning to put michelin powercup 28, as theyre wider than average 28's

I've been using 28mm PowerCups on 24mm internal rims and while the tyre casing is wide (meaning the tyre blows out to about 31.5mm) the tread width definitely isn't. I can see from the scuffing that I have been riding on the sidewall quite a bit. I wouldn't recommend those tyres for rims that wide, and probably only for 21-23mm internal width.

d50cu-28 t800, in house hubs, carbon spokes, 1316g. Can't wait to get them in hand.

oh well..
.... the tires have arrived. mine's the clincher ver.
worse comes to worst, i'll just put on my rears, on both future d50cu-33 n my parcours chrono, since they seems have better puncture protection that gp5k clinchers

Yeah glossy with some small decals

Yeah, I don't really understand why many (?) people here are going for those 26 mm inner width rims for road use with narrow tires. ETRTO recommendations don't exist for nothing. You can usually go a bit further than recommended, but it's a bit of a gamble.
Unless you want to to exclusively run 32+ mm tires, don't get those rims!
That said, it would be great to see something between 21 mm and 26 mm rim width. Something like 23 or 24 mm would be pretty versatile.

What frame are you running these on? What’s your max clearance?
I want to run 32mm tires on a new frame with a max clearance of 32mm. Wondering something like the 26mm IW/33mm EW is pushing it a bit far unless I get something like the LT 301D.

32C clearance, or 32mm? There's no standard. Sometimes a seller will start saying 30C, then start saying 32C instead because it's what clients want to hear. My lt268 has plenty of clearance for 34mm, or more. Velobuild 177 claims to clear 32C but various users showed that it doesn't.
Best is to ask the factory for the CAD drawing and how much space there is between seat stays. That's what long teng sent me when I inquired before ordering my lt268.
In theory, 32C clearance should allow you to run 32C with a 33mm rim. For aero purposes, I'd suggest 30C on 33mm rim though, as the 30C will measure wider than 30 on a 33 rim.
-
as reference, in my tt-x38 with rims 25 iw and 32mm gp 5000tlr they are 33mm real
and this is the space in the frame that claim 32 max tire
can't wait to receive the t1100 wheels

Serge, thank you for the clarifying information. I mixed up clearance with wheel width. I’m leaning towards the CS-R01. Peter sent measurements of the chainstay which put it around 38mm at the narrowest. By my estimates that would give the frame 2.5mm (5mm total) on either side to clear a 33mm OW wheel. I like to go as wide as I can to support 30-32mm tires. I’m just unsure if 2.5mm is enough clearance or pushing the limits of what the frame can support.
-
Are you not susposed to run a 28c tire on 24 internal rims?

Are you not susposed to run a 28c tire on 24 internal rims?
ETRTO guidance and UCI rules would say no—so as of mid last season this would be an illegal combination for racing on the basis of safety. While blowoffs are the catastrophic failure, the more common issue of too wide of a rim is riding on the sidewall and getting more punctures.
The C on tire sizes has nothing to do with width—it’s the designation for the bead seat diameter (BSD) of the rim (622mm). The format you all are seeing are looking at is referring to the different dimensions of the rim. 700 is a size designation that is supposed to the OD of the system at some arbitrary tire size that was historically used. The only place where this is still relevant is for 650b vs. 650c. Tires are specified in the format of [size designation]x[width][BSD].
Actual tire width for road tires is specified on a different rim width thats sort of standard and sort of manufacturer dependent. Most 28s are specified for a 19mm or 21mm IW rim for example and most 32s are to a 23mm or 24mm IW rim. 34+ is usually true to size on a 25mm IW rim.
To make matters worse there are two different ISO standards for tire clearance to the frame. 6mm is the off-road standard that gets used on a lot of allroad and gravel bikes. Some manufacturers (e.g., Trek) use 6mm on their road bikes too. 4mm is the road standard that also sometimes gets used for allroad and gravel bikes.
If you want to make sure a tire / rim fits your bike the best thing to do is measure or get a dimensioned drawing of your bike frame to compare. Most fork and frame manufacturers can provide this if its not in the listing.
TLDR: for road widths 23mm IW width rims give you the most options. 24mm-25mm is good too as it allows you to fit 30s. Measure your bike and the tires. You probably want 4mm of clearance on all sides of the tire and similar to the rims.

Yeah, I don't really understand why many (?) people here are going for those 26 mm inner width rims for road use with narrow tires. ETRTO recommendations don't exist for nothing. You can usually go a bit further than recommended, but it's a bit of a gamble.
Unless you want to to exclusively run 32+ mm tires, don't get those rims!
That said, it would be great to see something between 21 mm and 26 mm rim width. Something like 23 or 24 mm would be pretty versatile.
Well, it's hard not to see the direction of the industry. With Enve ses line, their 25/33 width, they recommend 27c as a minimum and they literally state "aero optimized tr tyre size". With the trend towards wider tyres, and having 105% aero "rule" (and it really does mean something), it's really hard to ignore that.
Kudos to Serge_K for introducing me this trend, and recommending to go wider. I went initially with 28 ow, but told Peter if it's ok to change to wider option, and thankfully he approved. Cost difference is about 20$ per rim, even less.
On the same tangent, but a bit different topic. Chinese industry follows the trend. After all, all major brands ship their blueprints long before the product arrives to market. And they ship them blueprints to manufacturing plants, guess where? Well, China :) ...And don't you think that once they have their eyes on those blueprints, they won't use the opportunity to jump ahead of the rest? Meaning they'll have the similar product ready to be manufactured as soon it gets the hype from that major brand?
I bought my carbonda fm936 xc full-sus 2y ago. The frame was from 2019. And the geometry is still SPOT ON with the trend. If you go to 2019. and see the geo numbers on all xc bikes, you see huge difference with some noname chinese oem's that somehow made so progressive frame years before it was the "thing".
They follow the trends, and use simple logic to get advantage every way they can. It may be not so moral from some perspective, but damn, we can get up-to-date products with decent enough quality for a really good bargain. Take my money. :)

I don't know if I missed it, what is the maximum rider weight with carbon spokes and 21mm inner width of the tires?
-
I've been considering the 26mm IW wheels with the intention of using minimum 32c tires but just looked up the ETRTO and the min size recommended for 26mm IW is 35c tires.
Is it best to follow this guidance? If so then I guess I'd go for the narrower wheels but have to expect that'll result in a hit in aero performance.
-
32c will be fine, will probably inflate beyond 33 anyway
-
Then get the new uni rims from yuanan that are 23iw and 32 external
Not seeing uni rims on their site with 23iw and 32 external. Are these not listed yet?
-
their website is pretty useless. Best to liaise w Peter on whatsapp, or via the forum. I never even look at their website anymore.
They have a new website but under construction :
https://www.xmcarbonspeed.cc/
-
That website lists the tire compatibility for the 26mm internal wheel
5, Compatible for 700*23C-43C tire (tubeless ready)
What does ETRTO know anyways im gonna go ahead and setup 23c tubeless

If ENVE recommends 27c tyre as best aero optimized for 25iw, then for sure you can run 30c on 26iw... That's my logic anyways.
edit: just to put a good word for Peter here on forum... this was his message the other day:
"Hi Ivo,
This is the tracking number by UPS: XXXXXXX
BTW, I paid extra $48 on shipping because you are from remote area :( But it is OK, hope you like our products
Best Regards,
Peter"
I don't need to say much more. Of course I payed the man the difference. But the fact he didn't even ask for it is... hands down.
-

ENVE has a specific list of tires tested to work specifically with their rims. There is no generalizable design principle here that can be applied to other wheels as the problem lies with the tire geometry, rim geometry, and the tire-rim interface
There are two sets of somewhat conflicting general recommendations. There are the ETRTO-based charts from the tire makers earlier in the thread, but also their general recommendation that there be a minimum of 5mm between the marked tire width and the rim's inner width. Many brands, including ENVE, Zipp, and Hunt, do not like either recommendation. Ultimately, those in favor (Continental, Mavic, etc.) won out, and the UCI adopted the 5mm recommendation as a rule. This forced teams like UAE to use the 30mm GP5000 S TR and move away from the 28mm TT TR tire.
This became an issue because of a bunch of high-profile tire blowoffs, largely on Zipp wheels, that resulted in injury to pro riders. However, there are also a lot of anecdotal blowoffs of other brands as well that you can find by searching other forums.
At the least, I would follow the 5mm rule on this one and run 32mm tires, as the consequences of a blowoff are the same as rolling a tubular tire off the wheel--if it's on the front, you will likely crash. I plan to follow both the tire maker charts and the 5mm rule, as I like not crashing.

I'm very interested in buying a set of wheels from Peter for a new build.
Looking at the 50mm 26iw 33ow rim.
However, I am unsure which free body I should order. The HG or XD.
I have not yet bought a group set for the build. I might go SRAM AXS or maybe just Ltwoo R9 (non electronic).
Could anyone provide some guidance?
Thanks!
-
Figure out the groupsets first. SRAM = XD, anything else = HG

I believe you can ask Peter for spare freehub for cheap price probably. So order HG and ask for XD as well. I wanted to but decided to go with shimano so didn't need to.

Have anyone got rim brake version of wheels and can share the opinion?

Actually that is a mistake by my colleague Allen when he listed the products, he copied the spec. but didn't revise the information for different widths rims/wheels.
On these 26mm inner width rims, we suggest 28C minimum.
-

Thanks! I took your advice and ended up ordering a Shimano 105 11-speed groupset.
Now I’m a bit confused thought since there seem to be HG bodies and HG road bodies?
Is that so? Will the HG body from Peter work for 11-speed Shimano?
I feel I’ve biked long enough to know this stuff but oh well :-[

Ordered mine and can't wait for them! It's been said million times, but Peter was incredibly helpful and patient with all my annoying questions :-[

Guys, since these will be my first carbon rim build, I wonder if the nipple washers still a thing here, cause DTswiss (rims I mostly build my mtb wheels on) do recommend nip washers. I asked Peter and he was pretty clear: nowdays they are rarely used. So what are your recommendations, or practice/experience? thanks in advance!

I would go with what Peter says. I'll be ordering a wheelset this week/next week. Just working out the last details. Years ago I ordered some stuff with him and he was very helpfull in the proces. I think I'd trust him on the wheels/no-washers (I also don't see them anymore on other hi-end carbon wheels, and I did have them on my last Alu MTB and race wheelsets),

I sure don't mind couple of grams less on my wheels. ;D
My wheelset and xc rims are still in transit. Landed in EU today. Should be arriving next week. The only bad part about chinese oem parts is... the wait game. Waiting on my vb268 for a month now :'(

Peter send me a photo of my wheelset
Lighter than expected!

That's really great weight. Mine, 24/24h t800 are 1420g. 200g of savings is pretty awesome.

Got an order in for the promo wheelset, should be around 1250g. Now I'm anxiously waiting, I hope the shipping time won't be more than a month.
Had contact with Allen via WhatsApp, apart from the weirdness of ordering something via WhatsApp, the experience was great, friendly, quick and helpful respones.

I've ordered the 13 of november and the wheels are ready to ship today.

Thanks for the info, that sounds reasonable. I would want them at the end of January to arrive at the latest. If it does not get stuck in customs, that should work out then.

My wheelset finally arrived. Peter asked me to post a review which I'll gladly do! The wheelset uses D50CU-28 rims with the in-house hubs and CX ray style spokes. As a specialty I ordered the variant without nipple holes. This makes for a painless and more reliable tubeless setup for just a little bit extra cost. Wheelset came in slightly lighter than expected at around 1330 g. So far I've put on GP5000 S TR tires which was indeed painless to do, it worked much better than on my older rims for some reason. No tricks needed, just put on the tires, a bit of pumping, done. I'm still waiting for other parts for my bike build, so I haven't used them yet, but from what I can see, everything is solid and they run perfectly true, too. Freehub sound at first seemed extremely loud, but with tire and cassette installed, it now sounds a bit muffled and much better.
Edit: by the way, I also ordered a spare freehub (because I've always had bad luck with freehub bodies for some reason). This was very reasonably priced, I think at 25 USD.
Edit2: now I see D50CU-28 is now available in T1100 too! Damn those rims are light! Maybe I should have waited a bit lol! I'm still satisfied since my wheelset is really good value for money though, got the basic T800 variant of the rims. The T1100 rims are probably quite a bit more expensive.
-
Fat wheels arrived today :)
Happy with the quality. Tyres seated well, but fitting them on the rim was... well, let me just say my fingers huuurt really bad.
28c front 30c back - thanks to SERGE_K guidance. They fit really nice. Also I ordered xc rims and managed to lace the wheels today as well. And I'm really happy with the weight. In a day or two, VB 268 frame should arrive and so will my road bike saga begin.

Hello everyone,
First of all many thanks for all your efforts on the forum, it's great and helps me a lot - keep up the good work.
Based on your experiences and reports I have ordered a wheelset (and handlebar) from Peter. And I can and will pass on your opinion - it was a great experience and the products are really very, very high quality products. Peter helped me a lot, even when my questions were annoying, he always answered immediately and helped me - thank you!
For the wheels I ordered the new D50CU-33 T1100 rims with carbon spokes and Peter's in-house hubs. Weight 1,225 gr. The plan is to use 30mm tyres. When I have fitted them I can give an update on the actual width of the tyres if you are interested.
I am also happy with the integrated handlebars, I just have to look for suitable spacers.

Guys I've notived the rear wheel is out of dish, and it bothers my ocp. Difference is not negligible, 4mm, or in other words, double the distance. On one side there's 4.1mm distance to the rim, and the other - 8mm. I know how to dish it, but it shouldn't be that big difference imo. And the problem is I don't have the spoke holder to keep the spoke from turning while re-dishing. Can anyone give me advice? I'm willing to try to re-dish it, but if the nipples are glued, and I don't have the spoke holder, that might be pretty impossible i belive.

I don’t know whether the chain stays typically would be completely symmetrical. drive side needs to clear the chain rings

Was thinking about that, but tire is offset with regards to seatpost as well.

You really need to put it on a trueing stand and measure it. The bike is not a reliable measurement.

I stand corrected. Wheels are in perfect dish. It's the vb268 dropouts that are causing slight misalignment. I managed to fix it though. Mea culpa. Wheels are 100% straight, round and dished properly.

How wide are these spokes? Will hidden nipples be an option at any point? Considering a 65mm t1100 rear wheel when you get the new hubs. (unless I find someone who makes something like a wide, 70 mm deep rim)

The spokes on that wheelset in my last post is 3.8mm, same as Farsports uses on their wheelset, and 5.0mm too. We have a bit more expensive ones 3.2mm carbon spokes like some big brands use on their wheels as well as attached.
Actually the nipples on carbon spokes are already hidden, they are not like the regular stainless spokes, you can tell from the picture. The nipples on carbon spokes request special tool to screw, that is why almost rims built with carbon spokes have to be drilled with access holes in the rim bead.
We are going to release the new 20/20h hubs for carbon spokes end of this month. So the wheels would be pre-ordered to customize now.
-
Could you tell us which bearings will be used as well ? 6803 , 6903 or others ?
-
I just ordered a 50mm gloss, carbon spoke, wheelset from Peter with small gold logos on the rim. Communication went good. He replies fast to questions and did send me some photos to helpt me choose. I'll update upon receiving the wheelset. Looking forward :)

Current we use these sizes on our 24/24H in-house hubs with enduro steel bearings for regular stainless spokes, and 21/21H hubs 20/20H hubs with TPI ceramic bearings for carbon spokes: 6802 on front hub and freehub, 15267 on rear hub except freehub.

Yes, I know the actual part that acts like a nipple on carbon spokes is internal, sorry. What I meant was if there was any possibility of hiding the metal spoke part like Magene and Scope do with stren spokes

I am interested in hidden nipples as well - I am unable to read stuff like https://wheellabkr.imweb.me/Blog/?q=YToxOntzOjEyOiJrZXl3b3JkX3R5cGUiO3M6MzoiYWxsIjt9&bmode=view&idx=18095954&t=board (https://wheellabkr.imweb.me/Blog/?q=YToxOntzOjEyOiJrZXl3b3JkX3R5cGUiO3M6MzoiYWxsIjt9&bmode=view&idx=18095954&t=board) and not be affected by it ;D
Hidden nipples with 50mm rims is almost as aerodynamic as external nipples with 55mm rims, at a lighter weight

Thanks Peter. The reason I asked is because I was told that both Farsports and WindSpace Hyper and Farsport use 6903 for lower rolling resistance. There is no option to go for 6903 and still stick to ceramic and carbon ?

I´m curious, what was your production lead time? I ordered my wheelset on the 29. and still dont´t have any information on whether mine is in production or not.

FWIW, I tried to reverse Wheel Lab's assertion of watt savings using a rotational drag-only model and think that 20 carbon spokes of this design should be very similar to 24 CXrays with external nipples.
However, Hunt did actual testing of external vs. internal nipples for their Sub50 testing, including the translational component, with external vs. internal nipples that their measured difference was 1/5th of what Wheel Lab claimed (at 0.2-0.3W per wheel). They also showed that blunt trailing edges on the front wheel have similar effects as internal nipples and that they do compound. On the rear wheel, they showed similar gains going 10mm deeper--even though, for weight reasons, they chose not to take that advantage. All of this stuff is very marginal.
If you are running 32mm or 28mm tires, it's hard to see a better value than a pair of D50CU-28 or D50CU-33 with the upcoming 20h hubs if you want a light wheelset, especially if the former is ~1150g. If you are willing to step into the 1250-1300g range, I think some choices are likely a couple of watts faster that are worth the weight tradeoff, though, in this price range, they would be just as unproven.
-
I'm just waiting for one of the bigger players to extend the bladed section and reduce the round section of the spoke of this design as much as possible. Carbon spokes have gotten plenty thin and deep already, so that's the biggest remaining room for improvement in aero. Eyeballing it, the stren spokes on newmen, scope, winspace, cadex, (crw? conflicting info) etc. have it the worst and farsports considerably better, but then they now have those gigantic external nipples, so swings and roundabouts, I guess. Wheellab do have something in the works apparently, but nothing concrete shown yet.

Thanks for your thoughtful analyses and comments. I was just wondering what leads to the conclusion that the farsports version is better? I'm assuming you're referring to aero?
I'm also thinking about safety - it seems like none of the options really use bonding to hold the tension anymore which addresses my concern if it is true (I've had some bad experience with carbon adhesive pull-out in another application).
-

Do you think the 6903 bearings can really lower the rolling resistance ? I am not sure, DT Swiss uses same 6802 and 15267 on their hubs. At least so far we haven't any client saying our hubs with high rolling resistance or anything bad. Anyway we use good bearings, maybe just different sizes with others'.
-
I´m curious, what was your production lead time? I ordered my wheelset on the 29. and still dont´t have any information on whether mine is in production or not.
Normally we have the T800 version rims in UD matt available, UD paintless and T1100 version rims have to be customized, so the lead time on these wheels would be around 15-20 days. You changed your order from D50CU-33 T1100 to D50CU-28 T1100 rims on Dec 6, so the rims are still on production and they would be done in 7-8 days from today.
-
Thanks for the clarification, peter. I wasn`t aware the rims are basically made to order.
Had to change to narrower rims, because winspace is very stingy on clarifiying their tyre clearance on the slc 3.0...They can`t deliver the measurment of the chainstay gap at the wheel.
Be it as it may, i`m looking forward to the wheelset.

Yes, aerodynamically, the farsports 5mm spokes are better, othersise the designs sre basically the same.
Yep, LightBicycle made carbon spokes bonded to metal bit for a short while and they were an absolute disaster. There's still someone out there making similar spokes, though they've taken some steps to mitigate the risk. Most of the time they're still an inferior choice though. Their advantages are that they can be a gram or so lighter and fit normal hubs.

Bigger bearings usually means improved durability, not lower drag

Bigger bearings usually means improved durability, not lower drag
I know, normally on MTB hubs, no? Or mainly on front hubs? We use bigger bearings on our in-house MTB boost hubs for now.
-
On all hubs, but since mtb hubs see much higher and frequent impact loads, bigger bearings are more beneficial on them than road hubs. I think if dt swiss use 6802 on dt180 hubs, then they should be fine for most road riders.
Bigger bearings would theoretically have more drag as they have more balls, but that means the loads are distributed over a larger contact area, meaning the loads on individual balls are lower, meaning they will wear slower. But the larger contact area means there will be marginally more drag, virtually irrelevant amounts for bike applications though. Seals make magnitudes more impact on bearing drag.
The tradeoffs with bearing sizes in hubs are usually size and weight vs durability:
• smaller bearings means lower weight and smaller, fractionally more aero hub
• bigger bearings means better durability against wear and dirt ingress.

I don't know enough about bearings to make a definitive statement on size and choice of bearing regarding size, drag, and durability. I do know enough to know that it's more complex than this, and a first principles approach like this can be really misleading (same as saying X shape is aerodynamically faster based cross-section without taking into account other factors like varying yaw angles)
For example:
- Not all bearings of the same size have the same number of balls. In addition to corrosion issues, this is why i tend to avoid cheap ceramic bearings.
- Material choice and coatings can also matter.
- Preloads can be a huge factor. For example, if you are worried about the load on a smaller area but can manage preload well with the design, a smaller ACB might be a better choice than fitting a larger radial bearing in a design where preload cannot be as well controlled.

Thanks for the clarification, peter. I wasn`t aware the rims are basically made to order.
Had to change to narrower rims, because winspace is very stingy on clarifiying their tyre clearance on the slc 3.0...They can`t deliver the measurment of the chainstay gap at the wheel.
Be it as it may, i`m looking forward to the wheelset.
I have a SLC 3.0 in size L. Othersizes may have difference clearances.
The D65-33 fits with plenty of clearance.
Im actually considering buying the D50-36 for my SLC 3. The front would fit easy, the rear most likely fit fine, wouldnt want to go any bigger though

Peter would kill me, if i change the rim again :)
I don`t understand some chinese frame manufacturers and their tyre clearance claims. Winspace told me that the chainstay clearance would be already tight with a 32mm tyre...
How many mm on either side of the tyre to the chainstay with your setup?
-
On the SLC3 L, the tightest fit is between the widest point of the tire and chainstays. Bit over 38mm measured, so a tire measuring 34-35mm (a 32c gp5000 on a 28iw rim) would be a tight fit. The rim is wider than the tire at 36.6mm but the chainstays spread out enough that they clear this more
-
How do we think the vertical & lateral stiffness/compliance between a 20 carbon spoke wheel and a 24 steel spoke wheel would compare? Data would be better than hypotheses but I understand if it's not available.
I hear of harsher ride being reported on carbon spokes with less perfect road surfaces (ofc also with better aero & weight) but have to expect that 20% fewer spokes may offset that if the baseline was with 24 carbon spokes instead.
-
Depends who you ask for the subjective, but usually carbon spoke wheels would still be stiffer. Actual measured data on vertical and rotational stiffness is basically non-existent all we have are lateral stiffness tests. Also, fact is, most carbon spoke wheels are simply overbuilt. We were fine with 20 and 21 steel spokes on the front, why do we need to have just as many carbon spokes? It doesn't make sense.
-
Thanks, Toxin. That's consistent with the rabbit hole of research I've done over the last couple days. Appreciate the thoughtful discussion here from people more knowledgeable than I.
I want to get my order in but I'm having trouble picking between 3.8mm carbon, 5mm carbon, or steel CX-Ray spokes for my T1100 D50CU-33. I'm 60kg fwiw and assuming cross winds won't be an issue.
The extra cost of carbon spokes is significant but if it makes my bike more fun but not noticeably less comfortable on 32c tires or significantly less safe then it's probably worth it for me.
-
I would think that with 32mm tires at an appropriate pressure for your bodyweight, the type of spokes in the wheel make no discernible difference to the feeling of comfort.
-
The stress deformation plots of carbon and steel spokes aren't that different. Carbon spokes just fail at a higher load. No point going 3.8mm over 5mm

Promotion would still last one week through Dec 24. In future, we will list new products onto our website and shopping mall site: www.xmcarbonspeed.cc
Even after promotion closed, please feel free to contact if you had any question or requirement.
Since Chinese lunar new year is coming soon, we have arranged these T1100 rims for stock through the new year holiday (about 20 days): D45CU-28, D50CU-28, D40CU-33, D50CU-33, D65CU-33 rims.

Guys, did you order those wide wheels for the road bike?
Is 34.18 too much for a road bike.
I'm thinking about this wide option but I'm worried about the frame (winspace t1550 2gen). Will it fit the frame. I haven't frame yet so I can not measure it.

I wouldn't be concerned. I think winspace took notes from the western brands, and they understates their tire clearance. I am confident my SLC 3 could clear the D50-36, since I have D65-33 installed and have plenty of clearance.
I would be concerned with some of budget chiner brands, since their sales person likely copied the entire spec sheet from somewhere else, and did no confirmation

I asked because I am also afraid about ETRTO Standard.
Also watched https://youtu.be/FNKtEhH5KtA?si=kx-Ck3WFdht86ToD screen in attachment. Nobody uses 26 iw for road wheels.

i just placed an order of d50cu-33 with the upcoming 20H hubs after measuring my just arrived ttx38.
looking forward to the arrival of the wheelset , hopefully before cny
-
Highly recommend Peter and Xiamen Carbon Speed, really good and fast service. Weight was 1211g on my 50/55mms. Answered all my annoying questions and for 650 bucks these wheels are insane value. 1211g, ceramic hubs, carbon spokes, all the works. these are the 21/21 spokes and I don't know the benefits or differences to the new 20spoke ones but I'm excited to get these.
-
My wheels are being shipped. Dealing with Peter was a perfect experience once again.
Ordered 50mm, gloss with subtle gold details, carbon wheels. Weight is 1221,9gr, which is really good.
Looking forward to receiving the wheels. Just need to buy a frame now :)
-
Merry Christmas, guys, thanks for all your technical questions and requests, thank you from the bottom of my heart for your trust and support. You are the reason why we keep good quality service and products, make new stuff and move forward. Wish all of you 2025 full of successes and happiness.
-
Merry Christmas everyone. I just got my order in for D50CU-33 with the 20H hubs and carbon spokes, ceramic bearings, etc. Great communication from Peter and really looking forward to being able to see and test these wheels up close!

Ordered exactly the same with Peter! Communication great again, same as with my gravel wheelset.
-
New 20/20H hubs released. And the T1100 wheelsets some guys ordered before promotion closed would be shipped out in 7-10 days.
-
Hey, just another shoutout to Peter. Extremely easy to deal with. Answered all questions in a timely manner. I ordered a frame in NOV and received it in 4 weeks. Very happy with my purchase experience thus far. See the CS-R01 thread for my build.
Thank you Peter!
-
Allready received my wheels, even faster than expected. They look stellar! Box got a bit of a beating (as usual), but wheels are fine.
Also received the 2 bottle cages and a MTB-stem.
Now I just need to buy me a frame :D
For those in doubt: just order with Peter and be happy :)

-

Yes, we do have light weight MTB wheelset. And that combo wheelset would be $850/pair without promotion.
-
The weights are so light - I do worry that we're suffering Keith bontragers proclamation about light cheap and strong.
Loads of exploding farsports rims hitting normal potholes and bumpy road riding or gravel riding - xmc confident their rims are stronger? T1100.is very stiff and light but not very flexible / resilient
Or do they think that was because of overtensioned carbon spokes?
-
Like I say to most guys who order gravel wheels, we suggest them taking T800 rims, even T700 version for gravel use if they are heavy. T1100 version is more suitable for road use. It's obvious you can't keep lightweight, strong, cheap on same rim for all kinds of use. Just like you can't do lightweight wide XC MTB rims for AM or Enduro use.
-
how much do the 20h hubs weigh?
-
how much do the 20h hubs weigh?
Since the spoke tension on carbon spokes is much higher than regular stainless spokes, to make sure stable quality, we don't make these hubs extremely light like someone else do, our new 20/20H straight through version hubs weigh around 290g
-
Is it possible to get the hubs anodised in a custom colour?
Still in the middle of running cfd to decide which rims I go for. XMCS 65 with carbon spokes is a candidate for the rear. Sadly all off the shelf carbon spoke hubs are minimum 20 spokes at the front, so will have to go with steel for that.

Sorry, negative for just single hub to do anodised custom color. Unless we happen to do the exact color anodising as you want, but mostly it won't happen, ours hubs are anodised in black or titanium color.

Got my D50CU-28 T1100 in the Mail. Wheels look great, packaging is very good and overall quality seems to match expectations.
One caveat are the actual rim measurments. Actual measurments are 22mm internal and 29mm external instead of 21.4mm internal, 29,2mm external.
With the wider internal and narrower external width a 28mm gp5000 s tr measures 29mm and sits flush with the rim profile, so no rule of 105% to achieve here, if your don't want to have a 25mm tyre, which most of us certainly will not want. So in some way the rim profile is neither here nor there, neither fit for narrow nor really fit for wide tyres. I will get on with it, but this difference to the advertised measurments is the worst difference you can have in a rim profile. Both rims measure the same btw, so i don't think this is a unit variation problem.
Measurements done with a digital caliper and at multiple locations.
-
I find complaining about 0.7% difference in measurements quite remarkable.
Also, how confident are you that 0.6 mm narrower rim would give you actual tire width that conforms to the 105% rule?
-
29mm is the fastest tyre size on rhat rim at low yaw
-
I received my pair of D50CU-33 T1100 just before Christmas. With CX sapim spokes and inhouse hubs - weight of 1320 g. A bit higher weight because opted for rims without holes and as I learned, it means no carbon spokes available. I also opted for brass nipples. Built with GP5000 TR 30mm, real width 33 mm, and a total weight with ultegra cassette, 2x160mm disc rotors and aliexpress valves - 2440g. Excellent quality, beautiful hubs. Only done about 120 km so far, due to shitty weather and snow here in Switzerland, but really happy with it so far.
Excellent service and support from Peter!
-

Yeah, those are rounding errors... And why would you complain about wider rims these days :)
But hey, if you can't keep up with the next group ride, you know what the problem is... ::) It's that 0,001% deviation...
-
I forgot I'm in a cercle jerk. I'm just pointing out a difference in the rims from advertised measurments. I thought more information is always better. In the end you can take any learning from it that you want.
As you read in my post I'm very pleased with the overall quality. Following the 105 rule is obviously rather anal, but the original rim profile is designed to follow it, why wouldn't you want to know that it measures a bit differently.
I ride a lot in crosswinds so a good performance at yaw angles larger than 0 is a feature I want in a wheelset.
Would I be not satisfied with the wheels, I would have send them back, but I didn't.

I don't think it's going to make much of a difference but it's always good to know and feedback. :-) I think it's sort of expected if you buy parts from China although I think Peter held himself to a different standard.
I order a 52mm headset bearing once and the seller send me a 51mm, and claim that it was variance due to manufacturing... that was a WTF moment since all the bearings I had bought previously was precise to 0.1mm.
Anyway, looking forward to the rims from Peter. Still thinking about the Frameset though...

Rule of 105 is horseshit, it's the closest to useful at 0 yaw and even then it's not accurate. As soon as you start adding any yaw, it breaks down completely
-

Saying it breaks down completely is even more facetious than saying if don't abide to the 0.1mil you may as well run box sections.
So you think brr drum tests are meaningless because 'nOt ReEl LiFe'. ;D
-
Just measured my dc50u wheels which should have an internal width of 21.4, pretty much spot on at 21.5 and that could just be a fault in my calipers
-

Im saying this because I've run cfd simulations on various rim shapes with various tyre sizes. 105 just has no meaning
-
I think its a good idea to verify dimensions. There seem to be a pretty wide tolerance on rims and tires that I have seen. This is on the higher side of the small sample size I have measured, but not insane. Lets also remember that your calipers are not perfect either.
Regarding 105--this "rule" was christened in an era of different wheel shapes, narrower tires, and rim brakes. It's also often misused in forums in reverse of what it was intended for. It was to help you select the best tires for a given wheel, not the other way round. Its been abused and misused and isn't relevant anymore.
Rim profiles matter. The fastest U-shaped profiles for a front wheel can be a watt or more faster, particularly at shallow yaws, but the air detaches so much sooner that they aren't used as much anymore. I think the Hunt Sub50 paper documents this pretty well when they cover all the rim shapes they tested. If I remember correctly and did the math right at 48kph the fastest profile suffered detachment a few degrees earlier, but was like 1.5w faster. Is it worth it to optimize at that level? I guess it depends on you, but following the rule of 105 on a rim that's not the right shape for that rule to apply wont get you very far.

That great that you disproved a BS 25yo wind tunnel test with an even more BS CFD analysis.
I actually skip wind tunnel testing and CFD analysis, I acquire a rim profile in a .jpg file format and scanning with my eyes I am able to calculate the aero performance of a particular tire-rim transition with a 100% margin of error

A quick teaser. More details later...
Thank you Peter!!

build my wheels with gp5000 S TR 32mm and they are 34-35mm real
-
Got my first ride in, 2h30 Z2 at 0°C and wet roads, so can't say anything about the finer riding characteristics, but overall I like the wheels very much. Running 28mm front and 30 rear, which measure 29mm and 31mm respectively. Both tyres at 4bar/58psi, setup tubeless. That is the 50mm deep 29 rim outer 22mm inner width btw.
First impression is that the wheels strike a good balance of stiffness and compliance. The ride is firm, but not harsh, road vibrations are kept in check. Obviously that combination of tyre width and inner rim width doesn't provide a plushy ride, but they feel non fatiguing to me with my setup. Road conditions here are pretty bad and I made an effort to not avoid road cracks etc.
Cross wind stability is alright. Large close passing cars do create a small tuck, but I also tend to have a light grip on my handlebars. Steering always corrected itself and I didn't feel the need to preemptively brace myself for any passing car.

Looking forward to the review Pat, they look amazing on the SL8 too, I thought they might look a bit too wide but not the case at all.
Curious if you will notice a difference in feel with the GP5000 STR tubeless, instead of with TPU tubes. I bought a new bike with the STRs + TPU tubes and they felt so...numb I guess, coming from the GP5000 clinchers+TPU's I was running on my other bike. I even noticed when I flick them they would give a dull thud, where as the clincher+TPU would give a nice balloony 'ting'.
I'm currently on Shimano C60 wheels, but would gladly consider selling them for these if they seem good. Save myself 250g or so, wider profiles so I can comfortably run 32mm tires for that smoother ride!
-
@Peter: Any chance you will make a rim with 34mm external width but more like 23mm internal? I think an inner width of 26 is excessive for road tires. Even for 32s it's a bit much. And personally, I also think it hurts comfort. If tires are too stretched out on the rim they don't feel as supple anymore. Tubeless helps. But it would still feel better with a bit less internal width, IMO.

We might consider to make 23-24mm internal width rims this year, but I don't think outer width on these rims would be 34mm that wide, it should be around 31mm.
-
Finally got my hands on the wheelset and so far I'm happy with it. 65mm rim with 26mm internal with in-house hubs and pillar 1420 spokes weight just under 1500g. The paintless finish looks fantastic. 30mm Schwalbe Pro one measures around 33mm and sits flush with the rim
After using this wheelset for hundreds of kilometers, I'm quite happy with the wheels overall. There's one drawback however worth mentioning. I use my tires tubeless and when deflated, the bead tends to unseat probably due to the width of the rim. It might not be a problem for most but since I travel a lot with my bike on the plane and you are always required to deflate the tires that's quite annoying. Once unseated the sealant starts leaking and you have to seat your tire at the destination and I don't carry a floor pump with me. I'll try adding a bit more sealant and hope it will glue the bead in place.
-
It might not be a problem for most but since I travel a lot with my bike on the plane and you are always required to deflate the tires that's quite annoying.
Apart from airline regulation there is no real reason to deflate tires for flights. Airline has never checked mine so have flown with normal pressure.

How much did the wheels cost you if you don’t mind me asking? Looking for a budget set of carbon wheels for my old CAAD 10!
Thx

Meant to reply to this ages ago, and seeing Patrick's YouTube today reminded me...
Peter kindly agreed to make the following for a monster gravel bike, and the results are absolutely brilliant...
D40CU-33 T1100 rims UD paintless 28/28H
Carbon Speed in-house ratchet boost hubs with steel bearings 6 bolts straight pull for 110*15/148*12 with Shimano HG driver
Sapim CX-Ray spokes

We might consider to make 23-24mm internal width rims this year, but I don't think outer width on these rims would be 34mm that wide, it should be around 31mm.
A wide rim in the 55-60mm range would make a perfect rear wheel to match with the 50/33 front, something similar to Roval CLX II or ENVE SES 4.5

It seems like xiamencarbonspeed is gaining some heavy traction. Even on a german forum more people are looking into them and are buying wheelsets. I hope xiamencarbonspeed can keep up their good quality to price ratio. Price hike upcoming with the increased demand?

Thanks for your attention and feedback. We are on Chinese Lunar new year holiday now, don't worry, as I said in my first post, we will keep up our quality products and service as over the years, I believe our top grade quality products are still most cost-effective, the pricing should be very reasonable.

i just got my xmcs d50cu-33 wheelset from peter, well packed. peter notified me item should have arrived, but i was away on vacation.
wheelset arrives at 1167g.
my setup:
- d50cu-33 with 20H straightpull spokes
- rt-cl900 140 rotors
- tpu tubes
- michelin power cup 28mm clinchers
the powercup ballooned to 32mm. powercup clinchers are inown/reported to size bigger than advertised.
already got 160km of ride on my tt912 frame(my x38 build got delayed), the front really absorb more road buzz compared to my 77/86 with fron gp5k 28mm.
speed wise i cant tell if its any faster to my 77/86, as different tires.
but in crosswinds, its so much easier to handle the fronts.
chainstay clearance kinda tight ::)

Just another data point - my DC50U's on 20H 5mm carbon spokes and a Shimano freehub came in at 1180g, so a bit heavier than others.
Box a bit smashed up but the wheels were fine and ok. Seem true, haven't tested spoke tensions or ridden yet.
This was for UD paintless glossy though, so people buying without a coating on may save 10-15g.

Could you share some photos of your wheels? Am interested how UD paintless glossy looks like on these.
-
Are carbon spokes worth it? I'm worried they ride harsh and are more difficult to tension due to less stretching nature of the material. Looks and weight are great - price also justifiable. But are they actually better as for ride quality, serviceability and longevity?
-
What do you think of the MARBLE surface?
Does anyone have rims with this design?
I find them very interesting.

Carbon spokes are only really better for weight and maaaybe a bit of aero, but they will in general ride harsher, harder to service, easier to break (I've seen carbon spokes break when the rider in front kicked up a loose pebble into the wheel of the rider behind). They will feel stiffer but it's up to you to decide if you want or like that. In my opinion, if Pogačar can win every race under the sun with steel spokes, I believe you can too.
-
How loud are the hubs offered by Xiamen Carbon Speed? Is the freehub very "waspy" sounding? I only ask as Im not a fan of loud hubs (maybe one of the few now).
-

I asked for simple small logos with ud paintless glossy.
I've always thought that the matte carbon look just has a cheap open mould feel to it. I get it's the lightest option. The finish is really quite nice though on these.
My main worry is of course that they just won't survive the first rough road surface I hit nor will they survive the gravel racing I have planned. That and I won't be able to get a 30c tyre to meet rule of 105.
However, they were competing for my money with some LB Turbo 50's. To get the turbo 50's competitive in weight meant alpina hyperlight spokes and dt 180 hubs. That was 1980USD shipped (and that was at black friday prices, normally more like 2100). These were 870USD shipped.

I got one of the "new ones" and it was (fortunately) quieter than I expected. I think you can change the sound significantly by packing with grease.

I will buy only carbon spoke wheels from now on. Have now already several carbon spoke wheels and the differance is noticable. Much better acceleration, stiffness,... And I find them just as comfortable as steel spokes. And if one worries about that, just drop a few psi in you tyres. The rolling resistance differance will be practicly zero, but you add comfort.
Service? Still not needed. And 2 sets have +10k km, and one set a bit bellow 10k km. I have about 80kg and do lots of steep climbing with lots of out of the saddle outbursts.
-
Quite frankly I have nothing negative to report or criticize. Easily the lightest and best set of wheels I've used from a value perspective. Mother nature gave me one single day today above freezing, and I was able to get in a 3 hour ride Z2 ride with some intervals mixed in.
GP5000 STR 32c. Running actual tubeless to avoid another audience upheaval on my YouTube. Tires measure 34mm at the rim. 55 PSI
Video drops next week.
Pat yo, love the video dude amazing now I am more drawn into ordering one,
If you could tell us the specs of the custom wheel build you had on your video? so I could replicate that?
Looking to get that 1200 1100gm wheelset heck even 1000gm with 40-45mm depth combo if ever that option exist with Xiamen Carbon Speed
-
¸..... There's one drawback however worth mentioning. I use my tires tubeless and when deflated, the bead tends to unseat probably due to the width of the rim. ......
Did someone elso also notice that?
When deflating, that tyre comes from the rim bed?
This is kind of problematic issue. Not only for traveling, but also for simple periodicly sealant check. And with possible bigger puncture, you probably cannot just insert a plug, as maybe you will not be able to seat the tyre with mini pump or CO2 cartridge.

Thank you sir. These are the rims below. Just let Peter know the specific specs for the lightweight version/hubs/matte finish. Or that you want wheels similar to mine, and he will take care of the rest.

Its a giant safety issue on the road. Good grief, they almost banned hookless in the peloton over this. New rules require strict ETTRO compliance regarding tire size/internal width. So I don't know if was the poster or the rim, but that needs attention.

Definately a big safety risk.
I think I heard from some CRW wheels users also have this issue.

One person here is running a 26mm internal width rim and a 30 mm tire. Any chart I seen recommends a 35mm tire. At the end of the day people will do what they want and blame the product for their choices.

Pretty sure ETRTO or whatever is 5mm greater than rim width.
Obviously, the issue here is finding a 32mm tyre that doesn't blow out beyond 105%.
-

I didn't realize this (5mm or greater) and cannot find anything about it officially. Regardless of what anyone says the charts are there to limit liability if there is an accident.

D65CU-33 T1100 20/20H UD paintless wheelset built with 5.0mm carbon spokes weigh around 1315g/pair, sorry, not able to attach pictures for now
Do you have a max rider weight for these? Also curious about max rider weight for same build with tbe D50CU-33. Thanks.

I asked Peter as I ordered two sets of wheels (65/33, 50/36). It’s 120 kg.

You're confusing tyres blowing off over the rim and tyres falling off the bead lock into the rim well. The latter is no more dangerous than how a normal clincher tyre behaves on a non-tubeless rim when fully deflated. The former is the problem for hookless wheels, and is of course, very dangerous.
In any case, I've mounted GP5k and P Zero Race RS to my XMCS wheels, and they have stayed securely locked when the tyre is flat, even when rolled along the ground in this state. I'd go as far as saying they're the best behaving wheels I have for tubeless considering ease of mounting, inflation with just a track pump, and staying locked when deflated.
Regarding ETRTO recommendations, I have no qualms running 28s or 30s on these wheels because they are hooked, and the risk of blow off is infinitesimally small compared to hookless rims and tyres of any size. I'll note that Josh Poertner runs 32 mm tyres on his 29 mm internal width 3T Discus 45|40 wheels.

Concerned people might also consider road tire inserts nowadays. I believe we have passed the dark middle ages, and in a modern and progressive society, it's not illegal anymore. Fashion police will not arrest you.

I am really interested in the D50CU-33s. I run a Vielo V+1 as a mixed road/gravel bike and it looks like these wheels would fit perfectly.
I was going to go with new farsports Evo's but has some concerns about being able to true the carbon spokes or replace broken spokes. It seems no one here shares similar concerns about these wheels?
-
D50CU33 w/ T800 and 24/24 steel spokes is 1400g at $600 shipped to us
D50CU33 w/ T1100 and 20/20 carbon spokes is sub 1200g at $950 shipped
Spending 50% more on less durable wheels to save ~200grams is probably not worth it for any of us who dont race

It's not about being 'worth it' but about wanting it. Lighter wheels spin up faster and generally feel quicker - I swapped a set of alloy Vento wheels with a 35mm set of Bora's on my Master and it transformed the ride and looks even better (same tires). I tried the same bike with a set of HED Stinger tubulars and it was better again. If someone thinking light (whatever) is going to make them move up a CAT level than they are kidding themselves. Heck, if I wanted to save 200g I would just skip breakfast.
Oddly enough I just ordered these https://www.xmcarbonspeed.com/Productinfo.asp?f=1657. A 1400g set of gravel wheels for a road bike. I don't mind the weight extra weight at all ;)

I can't work out how the maths works out there.
Carbon spokes are c.2.6g and pillar aero are c.4.5g.
With 20h vs 24h there should be at least 90-100g difference?

I don’t know tbh. But I think I have found out it’s not even worth going carbon spokes. Easier to maintain the alu spokes I guess
-
Because the 21 carbon spoke hubs are heavy as shit
-
Apparently light enough to have a sub 1200g wheelset
-
Because the 21 carbon spoke hubs are heavy as shit
Really? Haha, 325g/pair on our 21/21H hubs, but still much lighter than DT Swiss hubs for carbon spokes, we don't use original DT Swiss hubs for carbon spokes, actually DT Swiss decided to make those hubs to supply to STREN who makes VONOA carbon spokes for many big brands, but firstly DT Swiss was too uncompromising on the price, secondly some brands don't want to use DT Swiss hubs for carbon spokes as well, so I believe you won't see current DT Swiss hubs for carbon spokes much longer.
Anyway, stable quality are most important, as I said when we released our 20/20H hubs for carbon spokes, we don't make them extremely light as some other companies do due to much higher spoke tension on carbon spokes. @Toxin, Have you seen anyone complaining about our 21/21H hubs except side entry so far? Maybe you are picky on weight of any part of bikes, but please don't say bad words on anything you haven't tried personally.
-
Anyway hubs are in the center of rotation so they not much affect on rotation mass. 50 grams +/- on the hub doesn't effect anything beside the complete weight of the wheelset.

If the material used for hub body is not so good, it might cause tension deformation on the sopke holes hub side because of high tension on carbon spokes, and even the breadth deformation in center of the hub body, carbon spokes might not be reused when you get quality problem on the hubs, that is why we don't suggest too light hubs used for carbon spokes if they are cheap as ours. Unless you use very good material to make the hub bodies meanwhile make them extremely light and stable quality, but they would be much more expensive though.

I got a couple of spare spokes too. I was told I had to fit the rim tape myself?

Applying rimtape isn't hard, take it as an opportunity to learn. Just take your time with it. There is enough tape on a roll to be able to mess up.

Good shout re the spokes. I assumed they would throw a few in but i will ask.

Does Cabon Speed have the tension specs for the spokes? Unlike steel all carbon spokes are unique to the model and layup and cannot be tensioned according to any table. What readings should we go for when tensioning with Park Tool TM-1?

I ask Pete about integrated bars and he has offered a 38/90 at a great price. I can’t find any user reviews- anyone here used them?

Hello everyone,
First of all many thanks for all your efforts on the forum, it's great and helps me a lot - keep up the good work.
Based on your experiences and reports I have ordered a wheelset (and handlebar) from Peter. And I can and will pass on your opinion - it was a great experience and the products are really very, very high quality products. Peter helped me a lot, even when my questions were annoying, he always answered immediately and helped me - thank you!
For the wheels I ordered the new D50CU-33 T1100 rims with carbon spokes and Peter's in-house hubs. Weight 1,225 gr. The plan is to use 30mm tyres. When I have fitted them I can give an update on the actual width of the tyres if you are interested.
I am also happy with the integrated handlebars, I just have to look for suitable spacers.
(http://)
Hi
How did you get on with the handlebars? What was the spacer issue? Been offered 38/90 at a good price by Peter with my wheel order and not sure whether to bite or look elsewhere. Thanks. Bob
-
Hi,
Which carbon fully integrated handlebar did you order from Peter?
In the website they have just one model, I don't know if they can supply different one.

Hi all,
Just wanted to drop in and give feedback about my recent experience with xmcarbonspeed & Peter.
I ordered this wheel set:
https://www.xmcarbonspeed.cc/products/carbon-speed-700c-clincher-tubeless-ready-26-mm-internal-width-disc-brake-road-gravel-bike-carbon-wheelsets
I chose the following:
--UD finish with paintless (imho, absolutely gorgeous compared to other finishes)
--50mm deep front and rear
--no rim holes (made setting up tubeless so easy)
--Pillar 1420 spokes
--brass nipples
--instead of 20F/24R, I went with 24f and 28R (I am 80-85kg)
I ordered the last few days of 2024 (~Dec 27), exchanged a few emails with Peter (who was responsive and great to deal with).
Since the Chinese New Year was in mid-to-end January 2025, I was thinking it'd be nice if I received the wheels near end of February.
Around mid-Jan Peter emailed the build was finished, and that he'd notify me when he received a tracking number. I thought for sure, weel, ok, the wheels will arrive end of February. This is Europe, after all. Stuff arrives slow. Well, forget that.
The wheels showed up at my doorstep on 1 Feb.
Packed great, box in good shape. I took the wheels out, spun them by hand and began to smile. Checked with tension meter, spokes were all within 5-8% tolerance of what they should have been. Took off the Shimano HG freewheel, and light grease was perfect around the inner hub. Wheels were true, and maybe the roundness could have been a touch better, but then I realized (from the wheels I have built myself over the decades) that these were just as good if not better than what I can do. Which is to say, the overall build is quite good.
I have been riding this wheelset for near one month now, 3-4 times a week (weather here is iffy this time of year, so I use my other winter bikes when it's really bad out).
With this new wheelset, there's been nothing to report. No surprises, nothing unexpected. Just the way wheels should be.
Well, that's a lie, there has been one thing unexpected.
For near 35 years I have been 'ROAD" riding, training, etc on alu wheels no deeper than 25mm and rim interiors from 13mm to 18mm (back in the 2000s I had went with 28mm external tires, but never changed rims).
These xmcarbonspeed 50mm, 26mm internal deep wheels? How to say this without sounding like a Koolaid drinking fool? They've been nothing short of "wow" eye-opening. Running tubeless Conti GP5000 TR 700x30mm on these 33-34.16 ext width rims, where the Conti inflates to 32-32.4mm (at 40 psi front, 50 psi rear), has been a joy.
The wheels snap to attention when I want to go (suddenly I am up & running). After 17-18mph, the speed these rims are more easily able to hold, plus the cornering confidence that comes on a 30mm tire on a 26mm internal rim? Again, joy.
I have come back home from my normal rides thinking "what?" I know and/or I thought that I felt like crap during some of those rides, yet there I am staring at either another new course PR, or better, knowing I had been fighting 25-40kmph winds, yet I am near my old course PR on that route.
Basically, my avg speed for rides has went up 1.5-2mph. I can't imagine what I am going to feel like when I get one of those days (that admittedly come less & less as I get older), where I feel I can rip the cranks off the bike & I am just powering fully over my ride. Will I pull off a 21-23mph ride like I used to be able to do when I was a young pup? Being an old dog now (a few decades now), where I was average only 16-18mph on my 2-3 hr solo rides, I am now easily averaging 18-20mph. At my age, for me, by myself, to be near 20mph rides? Averaging this?
If you've been riding decades, you'll know what a big deal this is.
Anyhow, back to XMcarbnspeed & Peter. It was thanks to Chinertown and this message board (and reading Peter's replies here and in other threads) that gave me confidence to make the jump with xmcarbonspeed.
I now face the problem that my wife (who 'road' rides too), has seen me too often grinning ear to ear when I come home. Guess what she wants? Her bike can only take a 28mm exterior wide rim, so I am not sure if Peter/XMcarbonspeed can do a similar build as above but just with different rims (rim brake rims) that are 28mm max external width but maybe with a 21-23 inner width.
I'm thinking a 25mm tubeless, with gobs lower psi, on a 21-23 inner width carbon rim, along with it being 45-50mm deep, is going to bring similar smiles to her face.

Last question! Any reason to not get 5mm spokes other than a marginal loss of stiffness?

I was torn between the 5mm and the narrower ones, same cost same weight. The conclusion I came to is they look "cool" so ordered them.

I ordered the same set, let's see.
In theory carbon spokes are stiffer

I don't know exactly if the question has been asked here before, I'm interested in the T1100 wheels, but not with carbon spokes but rather with the Pillar Wing 20 for maintenance purposes.
What is the exact difference between 21 and 24 spokes per wheel, are the hubs different or is the difference 36/54 ratchets?

21 and 24 spokes will have different rider weight limits, and more spokes will be more redundant in a event of a spoke break. 24F/R is most common for steel spokes. Could use 24F 28R if your a big boy, or 21F 24R if your smaller since more weight is on the rear tire.

I have emailed Peter regarding the wheels and relevant information, including the rider weight limits for the new T1100 wheel with a 20/20H spoke count on carbon spokes. I currently have the Craft 50/60s, which are 16F/21R, and I hover around 75 kg—80 kg when I’m feeling lazy—and they feel plenty stiff.
I might get a couple of pairs as well—the reviews, weights, and quality look fantastic, it seem like a no brainer!
I’d love to know who they OEM for!

Weight limit is 120 kg for 20/20

Hi all,
Just wanted to give some more good feedback about Peter/XMCarbonSpeed.
I reached out on 2/13/25 looking for help on a set of 65mm deep wheels for my Venge. He made some great suggestions based on my needs and we put together the following:
I chose the following:
D65CU-28 21.4mm internal width 28mm outer width rims 24/24H UD marble gloss finish
Carbon Speed in-house hubs 24/24H 36T rachets enduro steel bearings center lock straight pull for 100*12/142*12 with Sram XDR Driver
Sapim CX-Ray spokes
Sapim self-securing aluminum nipples
He quoted 20 days lead time for the build but I was notified the wheels were ready to ship just 2 weeks later. Attaching some pictures but I am so impressed with the speed and how great these look. They are in transit now so I will update once rec’d and installed but I am very excited to get these on the bike.
-
I ordered a pair of 65mm deep D65CU-33 w/ 5.0mm spokes, plain gloss finish, no decals. 26mm int/33m ext
Except I chose the T800 version over the lighter T1100 this time. Ultra-light wheels at this depth for myself is asking for trouble.
Weight should be around 1460g which is still lighter than comparable Magene, Winspace, Elite Wheels. Yet wider.

What do u do with so many wheels and bikes? XD

Ordered a set of wavy gravel wheels on the 13th and they have been shipped on the 1st. 24mm internal should plump up the 32mm gp5000 AS to near 35mm. Hope they fit the frame !
Screen grab from their website. Fairly light for t800 carbon and 24 spoke wheels IMO

Haha! I have a weird emotional attachment to my wheels than I do frames. Bike frames come and go. But great a set of wheels can transform almost any bike. I only keep the good stuff in rotation.

36T Ratchet Hubs w/ Steel Bearings
Sapim CX-Ray Spokes & Aluminum Nipples

Total Weight: 1334g
Planning to install Continental 32mm GP5000's w/TPU Tubes
During inspection, I noticed some small burrs around several spoke holes (images attached). Since I plan to run tubes, I want to make sure rim tape will provide enough protection to avoid punctures. I’ve reached out to Peter to see what he recommends.
For those who have received their wheels—has anyone else noticed this? Also, are there any other areas I should double-check before building them up?
Thanks!

That wheel was scratched a little bit during assembling and testion adjusting, that area was repainted, they insert those spoke holes with a stick to hold the wheel during painting, there should be some undried paint on the stick then left around the spoke holes, our workers did not check them again due to urgent shipping. I sent you an video showing how to deal with that. So sorry about this inconvenience.

There are some companies selling carbon spokes with regular nipple end, but we don't, since those spokes without stable quality.
But we can build T1100 version rims with regular stainless spokes.

My interest is only with carbon spokes (50mm, 33ext., 3,8mm carbon spokes). And I know that is way better to have the hub, that is specially made for carbon spokes.
Can you share any technical info regarding your carbon spoke hubs? Like which type and sizes bearings are used, weight,...
Do you maybe also have this hub with 24 spokes (rear only) or is it only 20 spoke option?

Landed here in Atlantic Canada yesterday (March 6th) safe and sound. Wheels were packaged well in a wheel specific box and look perfect.
FWIW I have bought wheels off ALI before and they just came in a large box stuffed with foam and these had cardboard separators inside the box and were in foam wheel bags and nothing else included although I did purchase a XDR freehub along with the included Shimano one.
For reference in my frame still has lots of clearance as I plan to use 32 mm tires.

Yes, currently we just have 24IW rims at 50mm and 60mm depths available. 60-24 front and rear 20/20H wheelset would weigh around 1250-1260g/pair. Sorry we don't stock all lengths VONOA spokes for all depths rims we have, mainly 3.2mm ones for 21/21H 50mm wheels. Regarding 20/20H wheels, all lengths on 3.8mm or 5.0mm spokes are available.

Probably slightly under. My 50/65 set in t800 is 1332, and they're the 26 internal.

That's a great weigh!
I Looked at there site, should not have been so lazy ;D so 75 +/-10g so if your lucky and want light weight 95g.
Currently I have CRWs and the were 1280g for 50/60, so 53g at half the price is fantastic VFM!

My second wheelset from peter just shipped, D50CU36 rims, t800, 24/24, pillar 1420 and they are 1350grams My first wheelset is similar to my new except D65CU33 and weight is 1500grams.
Based off my wheels and Pattys wheels here, it seems the T800 rim weights have decreased from peters wheelset from last year. T800 wheelsets are ~70grams less than what I estimated from previous wheels on this thread. I am definitely not complaining 8)

I just received a pair of 28mm carbon wheels from Carbon Speed last week. I have just finished installing the tire and rotors on. Overall I am quite happy with the purchase.
1. lead time: from the time I placed the order to the wheelset arrived at my doorstep took 12 days. I live in California, US. This is super fast considering it took them more than a week to custom build the wheels. I ordered by contacting Peter Xu through WhatsApp. He was very prompt and accommodating.
2. package: the wheels are well packed. no complaints.
2. Weight: the claimed weight was 1330g and the actual measured weight was 1268g --- 62 gram lighter than claimed!
3. The quality: the wheels seem to be well made. their inhouse hub sounds great. Actually I think it sounds louder and better than the DT350 hub.

I ordered:
- D50CU-28 (21mm inner and 28mm outer width) T1100 rims 24/24H UD matt 50mm

shipping today, thanks to Peter !!!

You would think this would happen more frequently with all the wheelsets I've reviewed over the years. But this is actually the very first time I received a super damaged packaged like this. Thankfully no damages or scuffs to the actual wheels themselves 8)
Using these 65mm for an upcoming titanium project. Thanks Peter!

my 50mm T1000 wheels just arrived. Super pleased - communication was great, and they arrived within a couple weeks.
haven't put many miles on yet - winter keeps blowing in, but QC looks good so far.

First road race of the year. The 100km course has a few (wet & gnarly) gravel sectors, so I went with 32c GP5000 STR which stretches to 34mm at the rim. Carbon spokes is manageable on gravel but not ideal. Even with cushy tires.
Currently at my best fitness ever. NP 235w which is 3.2wkg for 3 hours and 15 minutes. Doesn't really matter though because my both bike handling and tactics are awful. Out of place early, and got dropped by the much stronger Cat 1/2 dudes about 45 minutes into the race. Ah well on to the next one...

Are you sure it's the carbon spokes, not the wide inner width that makes the tire walls straighter?

Well done!
What frame is this and how long is the stem on that cockpit? I'm looking for freakishly long stem options for a friend.
Thank you sir!
The cockpit is the Tavelo AROW. 140mm stem and 36cm width. I've used most of the usual suspects when it comes to one-piece handlebars. The Tavelo AROW is my fav in terms of having a good balance of price, weight, stiffness, and ergonomics. EXS is way overpriced.

Two different thoughts bruh. It's the rim width making tires wider - and carbon spokes harsh on gravel even with 'cushy' tires. Peace out

OK. I thought the straighter sidewalls made the ride harsher, even if the tire got wider. Less lightbulb-effect.

So I got a quote for 65 mm T800 wheels with steel spokes and a 54T ratchet, priced at $754 shipped to the EU. The estimated weight is around 1550 g.
That felt a bit heavy to me, since my current 65 mm wheelset with steel spokes weighs about 1430 g — although it’s only 28 mm wide externally.
I then asked for the same specs but with carbon spokes. The weight would drop to 1400 g, but the price goes up to $945 shipped.
It’s a bit more expensive than I expected, so I’m still debating which option to go with.

Sounds about right for steel spokes.
How many spokes 20/20, 24/24 ot 28/28 and what hubs are being used?
Steel spokes are around 4grams a pop
And T800 rims around 495grams each
I have ordered 60/65 wheels from another suppliers T1000
Rim 60 450g +/-15g
Rim 65 465g +/-15g
H-Works hubs 20/20H 276g
5mm carbon spokes @2.8g each 112grams
Wheels 1303grams
Did ask and see if it was possible to hit sub 1300g but they cannot promise that but around that weight for a wheel of this depth is light.

Received my D50CU-33 T1100 wheels and they are sitting at 1.181g.
Michelin Power Cup 30mm ending up at 34mm.
The build is fine and the hubs are also nice.
Wasn't able to ride them yet, cause I'm still waiting for my frame.
Little minus: The surface (UD unpainted) is very sensitive, even finger prints are sticky and not easy to wipe away.
Guess I would change +20g for clear coat next time.
-
Cannot confirm that but I use Dynamic ceramic coating on both wheelsets.

Same UD paintless finish on wheels of both of you two. Actually it is very easy to clean the finger prints, just use some water is OK. And UD paintless finish is not that easy to scratch.

D50CU36 rims with 34c tires. I figured go as wide as I can and the SLC 3 ended up clearing these rims and tires with room to spare. Feels so good that I will probably keep this as my only bike & wheelset. My D65CU33 wheelset is probably going to a friend and my gravel bike is getting sold.

Thoughts on your SLC3? I still have mine but had to strip it down. Needed the groupset for my TanTan GR201 gravel build.
Dynamically out on the road it's a very agreeable bike. Very well planted and nimble. Winspace markets it to compete with the SL8 which doesn't make sense. But I get it. And it's not really far off the mark to be honest. Especially with identical components and wheels.
I've been scaling back my permanent road bike rotation. The SL3 definitely makes the cut.

My frame has perfect QC and seems very well built so I'm happy with it. Im probably not qualified to talk about ride dynamics. I do appreciate how it is able to clear these tires

36.4 on my calipers. A 32c tire may give you a more aero tire-rim transition if you believe in that kind of stuff ;)

D50CU36 rims with 34c tires. I figured go as wide as I can and the SLC 3 ended up clearing these rims and tires with room to spare. Feels so good that I will probably keep this as my only bike & wheelset. My D65CU33 wheelset is probably going to a friend and my gravel bike is getting sold.
Do you also ride on heavy windy days?
Will the wheels be stable in those conditions, that 50mm will be all you need?

Just what I need. Lazy commuting with a little tiny touch of aero homeopathy. Gratitude.

Hey guys,
I came across these wheels thanks to Patliean1's video (huge thanks for that!), and I finally decided to reach out to Peter and order a pair of D50CU-33 T1100 with steel CX-Ray spokes. I'm super happy with the wheels—they look stunning in person and are incredibly light! 1289g with rimtape applied.
Sorry for the low-quality photos; I haven’t had time to take proper ones yet.
-
65mm / 26mm int / 34mm ext
5.0 mm wide spokes. I chose T800 over the T1100.
Still lighter than I anticipated. Need to check again but I think around 1384g
Is it a paintless or glossy finish? I would say glossy, but I'm unsure.
Very nicely balanced build!

Glossy finish.
The paintless option saves only a hint of weight, but is quite the magnet to dust and fingerprints.
-
Vantablack wheelsets should be a thing.
-
D50TU-31 24mm IW T1100 version UD paintless finish weighs around 375+/-5g since the mold is new, it could be lighter after we make hundred of them.
-
My wheelset is almost finished!
The GP 5000 STR wheels were mounted without tire levers, and the complete set looks fantastic!
I also ordered the valves and tubeless tape from CarbonSpeed, but no project is without problems... ;)
Front wheel mounted, and the wheel maintains its air pressure without tubeless lubricant.
Rear wheel loses air after about two hours. :'(
I'm a complete "newbie" should the wheel be leak-proof without tubeless lubricant, or will it stay permanently with it?
The tape is probably not mounted properly?!
2nd question: I removed the valve core to fill it with tubeless lubricant later – reinstalled it for testing – and now the valve is completely leaking.
What am I doing wrong?
-
The setup does not necessarily holds air w/o sealant. It depends on the tyre and the tape. In my case with the Pirelli P Zero RS Both tyres mounted with levers no issues, the much looser thunder burts not without sealant.
So just fill in the sealant and give it a little shake. Then they should be sealed.
For the valve core: maybe it’s damaged. You tried another one?

Not yet, because the valves from CarbonSpeed are new ones.
I will remove the valve from the wheel and check it, maybe I did a mistake?

D60TU-31 24mm IW T1100 version UD paintless finish weighs around 420+/-5g due to new mold, as soon as the wastage rate of epoxy resin gets higher, the rim weight could be a bit lighter.
-
D60TU-31 24mm IW T1100 version UD paintless finish weighs around 420+/-5g due to new mold, as soon as the wastage rate of epoxy resin gets higher, the rim weight could be a bit lighter.
So in theory, when mold is pretty new, there is more wastage left on the rim? And the more time the mold is used, there will be less and less wastage? Does the same aplies also for the frames?
Does more waste influence the structure of carbon? Like in less stiff, more prone to fractures,...? Or is it only on the outside of surface?

Frame mold is totally different with rim mold, and the carbon fiber layups for frame is different with the layups for rim, but similar like that, new production frames on new frame molds would be a bit heavier. Anyway, the wastage rate of epoxy depends on several factors, new molds, different resin formulations, differnt molds materials, different carbon layups formulations, different factories production line operators etc.
We do the impact testing almost per 100 rims production to make sure the rims are still stiff and can pass 80J impact testing. And we need to maintain and polish the rim mold per 3 days, we need to prove the molds are still proper even per 1500-2000 rims production, if not, then we need to fix them. The structure of carbon on our rims wouldn't be influenced since we control the wastage rate under certain percent. But I am not sure about others'

interesting rim, but I don't see it on the website.
can this rim also be had with carbon spokes?
so carbon wheels with 50mm 60mm 65mm rim?
because if the 60mm size was available I would be interested.

Peter posted that the XM Cranks in DUB and Ti spindle could be ordered and the Chainrings.
Said he would post Chainrings weights and prices after the Chinese Labour Day Holiday 1-5th May.

They were very quick to arrive once shipped (less than a week). They look absolutely epic

My second set of wheels from Peter arrived yesterday. About a week and a half to arrive to Vancouver, Canada.
D45CU-28 T1100 rims 20/20H UD paintless
Black color in-house hubs 20/20H 36T rachets enduro steel bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
3.8mm carbon spokes
I weighed them at 1131 grams.
I set them up and raced a crit last night on them, which had a bit of a kicker through the start/finish line. Quick on the climb, generally stiff, and confident through the corners.

I've bought the 50mm with 26mm inner, would have opted for 24mm -> sweet spot!
-
F me that's light! For reference, interestingly, 1200g for the "same" wheelset by Peter, but using deeper / wider (50mm deep, 33mm wide rims) (D50CU-33 T1100 rims 21/21H, steel bearings, carbon spokes, shimano freehub)
I was wondering real life weight differences of that kind of spec between rim widths and what not, now we know. Dont ask me why your hub has 20 holes and mine 21, but that means the 1200g includes 2 more spokes & nipples, so the difference isn't only in the rim. Maybe the wider rim needs more spokes. Anyhow. to go from 28 to 33mm wide rims (and 5mm more depth), it costs under 70g for a set.
You need to have older style hub, The newest one for carbon spokes is 20H.
-
I recieved two sets of wheels on Tuesday, the communication with Peter and the service were superb! I ordered on the 15th of April, payed on the 16th of April, the wheels were shipped on the 22nd of April and I recieved everything in Germany on the 6th of May. One box was damaged during the shipping, but the wheels seem to be fine.
The first set is 50-33 T1100 UD paintless with 20/20H titanium color 54T ratched hubs and 5 mm carbon spokes, weight ~ 1166 g, intended use is my upcomming roadbike
The second set is 50-33 T800 UD paintless with 24/24H black color hubs and Sapim CX ray spokes, weight ~ 1329 g, intended use is gravel
I already did my first 60 km test ride on the T800 wheel set today and I am very happy. I saved about 600 g compared to my Mavic Allroad Disc and the acceleration from ~ 25 km/h to > 30 km/h is awesome (this is my first carbon set). The wheels are very stiff, but yet comfortable with 32 mm Schwalbe G One allroad. Once you get used to it, the handling of cross winds is also no problem.

I find it confusing, so I'll just ask, what's the difference between Steel or ceramic bearings ? I've got that ceramic is lighter, but concerning the durability, I've read that ceramic is better somewhere, and steel is better somewhere else, where is the truth?
-

Ceramic is great if you use Ceramicspeed as they have a lifetime warranty.
Personally if products come with ceramic I will take them.
But generally these are cheap Ceramic bearings as are the steel and they don’t last long I will then upgrade with high quality steel bearings like NTN.
-
Ceramic balls are harder, so they will wear slower, but require the steel races to be treated to be harder or the ceramic balls will wear them out quicker. In the bike industry, Ceramicspeed are probably the best regarding this and they last a very long time
You will hear claims about efficiency from brands selling ceramic bearings, but most of it is bs. The difference in material makes virtually no difference for bike applications. The biggest difference will be in the viscosity of the lubricant inside the bearings, and the seals on the bearings.
-
Nice! ceramic bearings or steel? If steel, it means that your different hub & 20 instead of 21 spokes saved c.30g vs my spec. (ceramic bearings are lighter).
Ceramic bearings. I was not keen to get ceramic bearings, but since they come standard with the 20H hubs…
Ceramic balls are harder, so they will wear slower, but require the steel races to be treated to be harder or the ceramic balls will wear them out quicker. In the bike industry, Ceramicspeed are probably the best regarding this and they last a very long time
I think they use as special high nitrogen steel for the race, Cronidur 30 or something?
-
I was considering buying a set of the new 24IW from Peter, for the spokes it's easier, carbon spokes tend to be stiffer and weight less, but steel spokes are more comfortable and maybe easier to change/to service ?
But for the bearings type I'm a bit hesitant, and don't know which one to opt for, considering I value durability and ease of maintenance (I'm not necessarily chasing those few watts here and there)

Anybody running the D50CU-33 or D65CU-33 with GP5000 S TL 30 or 32mm? If so, what measured width are they on these rims? I'm waiting for my D50CU-33 wheels, and i'm simply wondering about which of these i will go for.

Yes. 32c GP5000 STR. Stretches to 34mm at the rim.

Yes. 32c GP5000 STR. Stretches to 34mm at the rim.
Great, ill probably go for those then. 30mm would probably be better aero, but i think i rather take the comfort.
Bought T1100 50mm with CX Ray spokes, ended up at 1275gr for the pair. Quite nice.
Will be fun to compare D50CU-33 with GP5000 S TR 32c vs Elite edge gravel 45mm deep with Caracal Race. Both great tires, but this wheel setup will be over 200gr lighter per wheel. The elite ones weight 1380gr without tires.
-
Has anyone in the US ordered recently? I suspect purchases would incur tariffs, correct? Was really looking to get a wheelset soon, but perhaps I'll have to wait.

I own the 33 with 26 inner and installed a Michelin Power Cup 30mm which came up 34mm and a Vittoria Corsa Pro 30mm which came up 32mm.
The Michelin is wider with a rounder shape, the Vittoria mire pointy in the middle, bot sure which ones I will ride.
-
My friend measured a conti gp5000 30C at 32mm on that 33 wide rim. Which is why i chose 30C on 33 rim, in fact, for the rule of 105. For a heavy rider, aka, me, at the back i'd put 32C though. The 3 friends i ordered these rims for are all light enough that i did 30C front and back.
I read on bicycle rolling resistance that these michelin tyres aren't meant for wide rims, because the thread pattern that's meant to be rolled on is very narrow. But last time i checked i feel like the widest they made was 28C, so this might have changed. But it's because of that that i never bought them. I'm french, i'm curious how they compare w GP5000, given the rolling resistance tests pretty much the same and they're usually a tad cheaper.
I read the same, but I had a 28mm Michelin Power Cup (non-TLR) on 21 inner and the 30mm (TLR) on 25mm and now 26mm inner.
Narrow indeed, but will work.
The new Pirelli seem to be fine also.

I opted for steel on the 20H hub. 1170g for D50CU-33 T1100 20H w/ 3.8mm carbon spokes. Have not seen anyone post significantly lighter ceramic version of these.

I went for the 32mm GP5000 s tr tires since i'm used to gravel tires, comfort is important for me. I was also thinking about going the 30mm instead for aero reasons, but at the same time i'm probably a to week biker for even noticing the difference
-
FWIW another data point. I am running 32mm gp5000 AS TR tires on a set of Peter’s 24mm internal wheels and they measure 34 mm inflated to 55 PSI.
-
I run:
28 mm Conti GP 5000 on the 33 mm OW/26 mm IW rims, stretching to 31,5 mm @72 PSI
32 mm Schwalbe G One allroad 33 mm OW/26 mm IW, stretching to 37,4 mm @40 PSI
I did my first 95 km test ride on the T1100 20/20H carbon spoke wheel set yesterday. Compared to the T800 Sapim CX Ray set, it is ~ 180 g lighter + what ever the difference between GP 5000 and the G One is. The ride feels similar to the non-carbon spokes wheel, maybe a little bit harsher.
Concerning acceleration and cross wind stability, I think the difference is also only marginal.
Once again, I was amazed how „easy“ it is to accelerate beyond 25 km/h compared to my old alloy Mavic wheelset. I rode > 35 km/h in sectors where I previously only did ~ 32 km/h, but maybe that was only the hype for new equipment.
The biggest difference between T800/Sapim and T1100/Carbon was in my mind, what happens when I hit a big pot hole? After the first hour, I gained trust into the carbon spokes and rode the wheel set more or less like I always do. Of course avoiding bigger pot holes but not minding manhole covers etc.
Overall I am also very satisfied with the T1100 wheel set. Would I go with carbon spokes again for the minimal gains? Only time will tell..
-
because my 28mm Powercup clincher had a sidewall cut before my biketouring trip, i put on 28mm gp5k clinchers as thats what i have around.
on my d50cu-33, powercups balooned to ~32mm, while gp5k got to like a lil under 30mm.
as the gp5k sidewall kinda flush to rim wall, i think if you are taking onto some gravel part, its best to go bigger tire to protect the rim lip as i already had few scratches

I will also definitely go for 30 mm GP 5000 once my road frame arrives. I just put on the 28 mm for testing purpose, since I had those tires flying around. 28 mm GP 5000 are definitely a little bit to narrow for the 33 mm rim.
-
@Peter
Is there a rotor for N3W available for the 20h hubs?
-
just sharing info.
i have a 2021 aluminium tcr that i wanted to sell due to cant upkeep too many bikes n kinda narrow tire clearance.
this is what d50cu-33 looks like with 28mm powercup balooned to 32mm at the chain stays :P
/like 1mm gap on drive side(even rim gap to stays), n 3.5mm on other side

I’m still waiting for an update on the 18-18Hole hub that’s currently under testing—Peter must be swamped lately, as communication has been a bit tricky.
In the meantime, I’m in the market for a new set of wheels—something in the 50–60mm range, ideally using the wider 24IW or 26IW T1100 rims.
I’ve sold my CRW 50/60s, so I’m looking for a quality replacement.
I’m particularly interested in wheels built with the Vonoa SLR520 spokes (5.2mm)—the 4th gen carbon spokes that come in at just 2.3 grams each. It’s surprising how few OEMs are using Vonoa (Stren) spokes, considering they were one of the originals in this space. Maybe it’s a cost issue, or perhaps they’re simply not offering the 4th gen option yet.
Also the carbon chainrings—definitely interested once I can confirm the weights and will get a set as well.

Hi,
I got my wheels some months ago and I would like to give a little review.
The contact with Peter was really amazing. 8) He answerd fast and very detailed to my questions.
The delivery was perfect in time (as promised - got before pictures of the wheelset).
Wheelset (55 mm, Carbonspokes, paintless surface) is superlight 1178 gr., the paintless look is very nice. the spoke tension is super („all the same“).
Mounting tubeless tires was easy, without any issue.
I did some miles on it and I am very satisfied (stiff, good aerodynamics).
I can highly recommened wheels from Xiamen Carbon Sports, Peter is super

I'd also like to hear more about the wheelset. Which width did you get? Could you share what tyre are you using and measurements?
-
Hi,
the wheels have the specification:
Rims: D55CU-28 T1100 UD paintless
Spokes: carbon spokes 5.0 mm 20/20
Hubs: Black Carbon Speed new in-house hubs 20/20H straight thru version 54T rachets TPI ceramic bearings.
I use Vittoria Corsa Pro Speed 28 mm.
Actual I have only a picture of the unfinished bike. I don‘t take a lot of pictures in general,sorry.
-
Any chance we will see some fiber spokes on those rims one day?
I would love the additional comfort but i'm not ready to pay $2000+ for some fancy berd or goosyn wheels.
This could be the perfect package for my future All-Road bike ;D

I’ve decided to replace my CRW 50/60s, which I sold this week. They were fantastic wheels — super light and reliable — but I’m after a more modern, wider rear rim profile he CRWs rear if people dont know was 21mm inner and the front was 25mm.
For reference, my CRWs came in at 1282g with rim tape.
The DFS rim profile on my current 60/65s is similar to that as the XMC rims with 26mm internal, which I still like — but I really I want to give the profile of the new DC50 & DC60 CU31 models a go.
Here’s what I’ve requested for pre-order as I want the new up and coming 18/18Hole hubs:
Front: D50CU31
Rear: D60CU31
Spokes: 5mm carbon
Finish: T1100, UD paintless, no logos
Hubs: Requested with the new 18/18 Hole hubs expected at the end of the month
Oh and a set of the XMC Carbon chainrings as well!
Looking forward to the build — hoping this setup hits that sweet spot of stiffness, aero, and modern width.
I haven’t owned a set of XMC wheels before, but with all the great reviews on here, it honestly feels like a no-brainer.
Just have to be patient with Peter, as with a new baby on the way and work he is crazy busy!

Ok trigger pulled at 4am this morning UK time so I could get hold of the super busy peter!
And I was also able to order the new 18/18 holes hubs
Wheels $880usd
Chainrings 53/39T $165usd
Shipping & taxes $120usd
$1165 around £915gbp /1040uros
Add 5% Paypal 5% but that can be avoided if you are prepared to pay friends and family.
Lead in 15-20 working days for manufacture and a standard 10-18days shipping.
Could be a little longer as XMC are moving to larger premises but Peter will do his best to keep the lead in on track
Front: D50CU31
Rear: D60CU31
Spokes: 5mm carbon
Finish: T1100, UD paintless, no logos
Hubs: 18-18 Hole configuration black 54T Ratchet TPI Ceramic Bearings
Weight circa 1200grams
-
So around 400 g for the hubs and spokes. A little bit heavier than farsports who use bigger external nipples, but pretty okay

Hey Toxin
Thanks
Ok so around 3gram per spoke
So circa 290 grams which is the same as the 20/20Hole XMC hubs

Here is my D60CU-31 T1100 on my Spcycle r-088. They feel absolutely amazing - so quick - and even with the carbon spokes they are so comfortable thanks to the 32c tyres (which measure 32mm on the rims)
Cannot recommend xmcarbonspeed enough! Amazing products that are great value and Peter is so accommodating

That will be night and day difference. Did not use elite edge but some users called them not to stiff laterally, just a mid tier steel spokes wheelset. I had a better wheelses then the elites and changed to carbon spoke one and this was like changing fro alu rims to carbon. That's just next level. You will be satisfied
-
Even the difference is noticeable going from the 1st gen Elite Drive 65D to the D65CU-33 t1100.
Both have carbon spokes and are 65mm deep. But the Carbon Speed are stiffer and magically handle crosswind better.

I have juts sold my CRW 50/60s for a set of T1100 D50Front and D60Rear CU31s
Also have another Chinese OEM brand of wheel 60/65 T1000 carbon spokes so far been great

Anyone heard from Peter in last few days? I have sent emails and what’s app message and still not reply.
-
Yes, we had a chat yesterday on an upcoming gravel wheelset.

The man’s has a second child child on the way, and XM is currently in the process of moving premises so he is super busy.
Just need to be patient, i struggled to get hold of him
Last week but did eventually. Best to contact him during Chinese business hours which is +7 hours here in the UK on WhatsApp I found so had to get my ass out of bed early!

Hi all,
I just confirmation of my wheels being shipped, looking forward to having them in my hands 8)
Specs:
D60TU-31 T800 rims 24/24H UD matt
With access holes
Internal nipple build
In-house hubs 24/24H 36T rachets enduro steel bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
Sapim CX-Ray spokes
Sapim self-securing nipples
I went with these after discussing with Peter my requirements.
Usecase:
I am 83kg, do a bit of road racing and some races include a tiny bit of pavé or gravel sectors. Never a lot of sustained climbing. Hence the T800 rims for peace of mind and 24 steel spokes. I went with internal nipples to offset (theoretical, I know) 24 vs 20 (carbon) spokes.

You think T800 is stronger/more robust than the other options, particularly the T1100? I don't have a strong opinion one way or the other, just curious.
-
T800 is more flexible, which makes it less brittle. Because it's more flexible, they need to use more of it to make the rim sufficiently stiff. Because there is more material, it will be more robust.
-
I followed the same approach (after consulting Peter and some internet research) and chose T800 + steel spokes for my Gravel bike. The weight difference to T1100 + carbon spokes is just ~ 163 g and it gives me some peace of mind. I clocked in the first rougher gravel rides on trials and a long 200 km ride last Sunday, 530 km total so far. I am still happy, the wheel set was a significant upgrade and the wheels survived all beatings on the trials so far (I was kinda nervous the first couple of km)

Guys. We will attend Eurobike 2025, our booth no. is Hall 11.1 A72. Welcome stand by and say hi
We will release new gravel rim D53TU-41 as attached by then, hooked 53mm depth 32.5mm internal 41mm external

As if I already don't have a backlog of gravel wheels to feature, Peter goes and drops these LoL
For my TanTan GR201 gravel frame folks...these will be the meta wheel.

I don't like these super wide gravel rims. All you do is expose the rim to damage from rocks and such. It doesn't even do anything for aero because the edge of the rim is where airflow coming off an off-road tyre is absolutely demolished. If you're gonna make a wide rim, it's better to do it like DT Swiss (Swiss side) and Parcours, where the rim edge is relatively narrow, and then the rim bulges out closer to the middle. Safer and more aero.

Maybe a stupid question, but where do I order? Can i just use the website: http://www.xmcarbonspeed.cc/ ?

Depending on price and weight these will certainly be my next set of gravel wheels. Have been eyeballing the Nextie SGV, but have been not ordered since i emailed Peter about these a while ago, so i did know they were on track for this season. Hopefully they will match Nextie weight wise, and as usually have great price like xmcarbonspeed usually does.
I would say there is no problem at all with damaged sidewalls if you go >45mm width, and these are also hooked compared to 303 XPLR. I think smaller width will also work fine - but tire manufacturers have to design the tires for these kind of rims for that. (Smaller tire casing width lay flat, but wider contact patch - if 40mm should measure 40mm that is) I would even think it may introduce lighter tires for same width because of that.

If you want to protect the rim edge with the tire, then the tire needs to be wider than the rim at the rim edge. Now your tire+rim has an hourglass shape. So air flow can separate at the tire. And the space between the widest point of the tire and widest point of the rim becomes a void air must fill and will increase drag
-
Reason those new Goodyear XPLR tires have been a failure in tandem with Zipp's XPLR gravel wheels is simply because the tires aren't wide enough. Way too many side cuts since the side walls are exposed. This is according to conversations I've had with Sram/Zipp employees, and I'm certain Sram won't admit this publicly.
40/45c tires on a (HOOKLESS) 40mm external, 32mm internal wheel for gravel is asking for trouble. It doesn't even follow the ETRTO standards. Although I don't ever follow this myself LoL
A 32mm internal wheel "should" be using a 58 - 65c tire. But yeah no is gonna do that. For Peter's new gravel wheels I would not run anything smaller than a 2.0 MTB. Better hope ya gravel frame can clear that.
-
I urged Peter to design a new Gravel frameset next with at least 700x57 tyre clearance with at least 46T chainring. ;D
-
Does anyone know if XMC is already offering an integrated handlebar? Last time I heard about it it was on their plans
-
Out of interest, what is the lightest set of wheels xmcs can do?
I watched pandapodium the other day on YouTube at the bike show saying they would be selling a 900g ish wheelset soon.

ETA been using the d40/33 t1100 as gravel bike wheels for the last five months and they've been brilliant, thanks Peter!

It's an off road tyre, airflow is already separated because the off road tyre profile chopped it all up. The negative space creating a negative pressure area behind the tyre is actually a positive because it pulls that turbulent airflow back towards the rim so it can more easily fill the wake behind the rim.

Got my D50CU-33 t1100 setup with 24 CX-ray spokes per wheel last week. My set Weights 1276gr for both wheels. Received tubeless tape, valves and two GP5000S TR 32c tires, which i seated today and pumped up to 5 bars. Both of them measure around 33.7-34.1mm so actually almost 1mm narrower than i expected. Glad i didnt go for 30c which i was thinking about.
Now i just need my new Chaser ultralight discs, and i will take them for a ride.
Looks better balanced and stiffer than my Elitewheels Edge Gravel 45mm deep 31mm wide (24mm internal width), while also being about 100gr lighter. Fun times.
Will probably get a set of the new ultra wide gravel wheels as soon as they are available also!

I agree on this one. there are a lot of topics on weight weenies and trainer road forums on why those super wide rims are not a good idea for gravel and even MTB. Respected users and testers like DC rainmaker or go lama had a lot of problems with those exposed sidewalls. From my knowledge 28 internal is optimal for wide tires.

Those wide rims are a known problem in MTB for years now, resulted in many tire models with stronger and stiffer causing which negatively impacts rolling resistance.

I pulled the trigger also.
For me a combo of the 50 33 and 60 31 paintless 1100, without drill holes in the rim bed, with 3.8 carbon spokes.
Keep you updated, estimated delivery mid July.

Bought 50 mm for the alps
I will tell you how it goes

The 50’s are pretty stable in side winds, especially with an Aerothan on the front. When do you go?

I was waiting to hit the 1000 km with my review, and now I can proudly say that I can fully recommend wheels from XMcarbon speed and Peter. The conversation with him is/was a pure pleasure, he responded immediately and he has a lot of knowledge regarding the wheels and the bike industry, even better than frame manufacturer as he ensured me that the external width will not be a problem in my frame. I have Avenger Shuttle SL in size 58. In general I was looking something for the climbing and riding in the mountains so he recommended the D35CU-33 rims, so 26 mm of internal width and 33.9 mm external with height of 35 mm. I'm fully satisfied, the wheels are stiff, accelerating very fast, handling and cornering is a full pleasure. I have not issues with them, I felt very confident on quick descents. Climbing and ascending is a pure happiness and absolute delight. The wheels are quite wide, so those are much more comfortable than my previous Avians. On wheels I have XDR driver and 30 mm Goodyear Supersport F1 R TL tires, and installed tubeless system. The tape and valves were provided and the installation of tubeless was trouble-free, all done very quickly. The wheels were tested on Mallorca and mountains and flat roads nearby Warsaw in Poland. Last but not least, the whole set so wheels, valves, tires, cassette 10-44 etc. is 2275 g on my unprofessional scale so the excellent result for me. Summing up, I can fully recommend the company, the wheels and for sure, if I buy another set of wheels, it will be the XMcarbon speed! It's my honest review and opinion. IF you want to see some more photos of it, you have it here - https://www.instagram.com/marioooouzd/ ; https://youtu.be/P0qXn2RKBn8?si=qvGUf2R_SqKukAH0

A bit of an off-topic, Mariusz, but how's the Avenger frame?
-
So I will try to have it quick, as it's off-topic ;D My rating is 10/10, love the bike, especially during the climbing and descending. However he's doing very good on the flat roads. Having the XMCS wheels I feel they are just made for each other ;D I will do proper comparison to the newest version of Elves Falath EXP, I wonder what is the difference on flat and windy areas, where I live.

I received my 60/31 wheels last week and have done two short rides so far. Upgraded from the stock Roval CL50 wheels that have done 15000km (its funny that I got almost exactly the same for the Rovals when I sold them, as I paid for these - amazing value!)
I am really happy with the wheels - they feel great and seem fast. I had a lot of crosswind on the rides, and while not a problem, I felt the front wheel being pushed about.
-
Just received my set of D50CU-33 T1100 with 38mm carbon spokes, no decals. Weighted out at 1220g and my 28mm GP5000 with TPU Tubes measured out to 31mm
Excited to test out the wheels later today.

Hey Peter, could you share with us specs of the new hub?
-
Price for this set?
These aren’t my wheels, but they’re priced at $950 USD.
If you opt for the version without rim bed spoke holes, the price drops slightly to $910 USD. The extra $40 covers the reinforced spoke bed, as these wheels are more difficult to assemble without spoke holes.
Wheels with rim bed spoke holes are slightly lighter by comparison.
There’s also a 5% PayPal fee if using Goods and Services. If you'd prefer to avoid this, you can pay via Friends and Family, as I did.
Shipping to the UK is $120 USD, including taxes.
Production times are:
Without rim bed spoke holes: 20–25 working days (excluding shipping)
With rim bed spoke holes: 15–20 working days (excluding shipping)
I’m not entirely sure about shipping times to other regions, but generally:
US delivery takes around 5–10 days
UK delivery takes around 10–15 days
XMC are currently gearing up for Eurobike next week, so they’re extremely busy at the moment — this may slightly affect communication or lead times
-
Hey Peter, could you share with us specs of the new hub?
same as 20-20 hub
54T Ratchet TPI ceramic bearings hub weight is about 290Grams
-
And finally, my wheels are being shipped tomorrow!
Originally, I wanted titanium-colored hubs, but Peter is busy with Eurobike and wouldn’t have been able to send them out until afterward because the hubs needed anodizing. So, I was offered black hubs instead — no big deal since black was the original spec, but I had changed my mind.
New 18- and 18-hole hubs
UD paintless finish
CS-D50CU-31 disc brake carbon road rim: 50mm depth, 33mm wide, 24mm internal width
CS-D65CU-31 disc brake carbon road rim: 65mm depth, 33mm wide, 24mm internal width
Spoke holes on rim bed
5mm carbon spokes made from T1100 carbon
I was told the weight would be 1200 grams, but it came in just a smidge under at 1196g — beating my old CRW Gen 1s at 1280g and even the new ones at 1250g! 😄
Now comes the painful wait as I watch the parcel tracking slowly make its way from China to the UK… hopefully, it arrives quicker than expected! :(

hi sender, you who have experience with wheels, don't you think that 18 spokes per wheel are not enough to make the wheel rigid? I was thinking about wheels with 20 Peter spokes, but I'm held back by the idea that for a weight like mine, I'm well over 80kg, closer to 90kg, they are too delicate. can you give me your opinion? thanks
-
absolute stiffness will be fine with 18 carbon spokes, but I'd be very curious to see the balance of lateral stiffness of this spoke arrangement on the front

Hey! I know a bit about this ;D but not as much as some! – for context, I was riding my CRW 50-60S wheels when I was around 90 kg and had zero issues. Those wheels have a max rider limit of 100 kg and run 16 spokes in the front and 20 in the rear, also XMC use T1100 in there higher end wheels which is more expensive that most of the the other OEMS I know use T1000 in there higher end wheels.
T1000 vs T1100 Carbon Fiber
Both T1000 and T1100 are high-grade carbon fibers made by Toray, a leading Japanese carbon fiber manufacturer. But T1100 is a step above in performance:
Tensile Strength:
T1000: ~6,370 MPa
T1100: ~7,000 MPa
→ That’s around 10% higher tensile strength.
What does that mean in practice?
With T1100, manufacturers can build wheels that are:
Stronger under stress (better for sprinting, cornering, and heavier riders)
Stiffer with less material
Lighter, since fewer layers or thinner layups can achieve the same strength
Stiffness Difference (10%+):
A wheel built with T1100 can be up to 10–15% stiffer compared to an equivalent wheel made with T1000, assuming similar layup and design. This can translate to:
Sharper power transfer (more efficient sprinting and climbing)
Better handling at speed
A more responsive ride feel
Of course, stiffness has to be balanced with comfort – too much can feel harsh – but T1100 gives designers more flexibility to fine-tune that balance without adding weight.
Toxin probably has a bit more experience than me on this topic, but wheel stiffness depends on a bunch of factors: rim depth, spoke count, spoke type, hub quality, lacing pattern, etc. It’s not always as simple as just counting spokes.
That said, going from 18 to 20 spokes likely won’t make a noticeable difference in stiffness. If you’re really concerned, you might as well go up to 24 spokes, at least in the rear. Stiffness tends to matter more in the back wheel, especially for heavier riders. So you could run 18 in the front and 20 or even 24 in the rear.
To put it in perspective, adding 6 carbon spokes only adds about 18.6 grams (carbon spokes are around 3.1 g each), which is basically nothing.
Also, deeper rims are naturally laterally stiffer than shallower ones, which helps even more with wheel rigidity. Rim depth plays a key role in stiffness too, especially lateral stiffness, so it’s another factor to keep in mind when looking at overall wheel feel.
In general, increasing spoke count and switching from steel to carbon spokes both increase wheel stiffness. Carbon spokes can add around 8–15% more stiffness compared to steel. Each step up in spoke count (e.g., from 18 to 20 or 20 to 24) can increase stiffness by roughly 5–8%, though the gains tend to taper off beyond 28 spokes. The goal is finding the right balance between stiffness, weight, and comfort depending on your riding style and terrain.
By the way, what rim depth are you considering? And what wheels are you currently riding – have you had any issues with them?
Personally, I wouldn't want super stiff wheels either – it has to be a balance. But finding that sweet spot can be tricky. Some riders know exactly what they like and stick to that format.
A 50/50 or 50/60 mm front/rear setup is a great all-round rim depth option – enough aero benefit without being too twitchy or overly stiff.

Each step up in spoke count (e.g., from 18 to 20 or 20 to 24) can increase stiffness by roughly 5–8%, though the gains tend to taper off beyond 28 spokes. The goal is finding the right balance between stiffness, weight, and comfort depending on your riding style and terrain.
By the way, what rim depth are you considering? And what wheels are you currently riding – have you had any issues with them?
Personally, I wouldn't want super stiff wheels either – it has to be a balance. But finding that sweet spot can be tricky. Some riders know exactly what they like and stick to that format.
A 50/50 or 50/60 mm front/rear setup is a great all-round rim depth option – enough aero benefit without being too twitchy or overly stiff.
hi sender. thanks, you wrote an encyclopedic treatise. by rigidity I mean the lateral one, when you stand on the pedals and especially for the rear wheel. in theory the more spokes there are the less the wheel flexes. I am not entirely convinced of having 20 or worse 18 spokes at the rear with weights of 80-90kg, then I agree with you that in the vertical sense a good wheel should be not very rigid.
I am very undecided between the XMcarbon 20/20H by peter or the Elitewheels DRIVE II 50mm.
the farsport S5 with 18 spokes seem too flexible to me, even jo of pandapodium with his light weight found them not very rigid.
I don't see any other wheels around 1000 euros, perhaps the magene EXAR 508

Then go 24 in the back with XMC 28 seems a bit overkill with carbon spokes.
Or try another OEM like me
Zen or CBK

You also have options from Farsports on their Wheelsfar site.
https://www.wheelsfar.com/collections/carbon-spoke-467
I have with DTSwiss hub. 20front/24rear, 3,8mm spokes, which are supposed to be stiffer than +5mm ones. The wheels are everything I wanted. All extra weight is in the hub, so no added rotational weight.
There are also other setups upon request. Just scroll pages back on Farsports thread on WeightWeenies forum.

Bit of a follow-up post—I mentioned a while back that I’d ordered some carbon wheels from XM Carbon Speed. They arrived today: 50mm front / 60mm rear, 5mm bladed carbon spokes, 18-hole hubs.
Took them straight out for a spin on the Tuesday night chaingang ride. First impressions: they’re fantastic. A few people commented that they’re not the cheapest out there, but the build quality is seriously impressive.
Honestly, I think they’re superb wheels for the money, great quality. Really, really pleased with them.

Hello everyone,
Was looking trhough the discussion and I hace a few questions:
I weight 90kg. and I mainly ride on road but I sometimes do very light gravel for fun. I don't climb and I'm looking for a 50/55mm depeth wheel set.
The road condition is good where I ride so I'd like to get carbon spokes but considering my weight is it a good option ? Should I go for 20 or 18 is doable ? Same question for the spokes diamter, should I go with 5mm ones ?
Also, wondering if having covered spoke hole is a good choice in my situation (I understand that they less robust?)
I would like to treat myself and go for the highest possible quality carbon speed has to offer but I also want to ride safely.
Would very much appreciate you guys answers !

Light gravel I would go
20 front 24 rear myself
Spoke diameter depends what your after really 4/5mm for aero. Think light weight carbinnspokes are 3.1 or 3.2mm
Carbon spokes fine at 90kgs
Don’t do gravel but I’d assume steel or a rope spike would be more comfortable.
XM Carbon wheels have a 120kg weight limit .
Spoke holes on rim bed or not does not make much difference n
Personally spoke holes for ease of maintenance
-
Just under 1200. That's impressive. I've been running Peter's 50/65 with his hubs, carbon spokes but t800. Still at 1330. But thinking about something in 50/50 to climb.
Who's hubs are those?
-
Thanks for the answer !
Sorry more question:
Why spoke hole are easier to maintain ? (if you need to replace a spoke ?)
When I say light gravel sometimes I ride maybe 10% on that kind of surface:
24 IW ok for a 32mm tyre ? I don't think 26IW would fit on my frame.
PS: your new wheel set look sick!

XM CarbonSpeed hubs the new 18/18hole
However they also have a 16hole front hub in development no timeline current
50/50 would be say 1190 estimated
50/60 were 1200 estimated

Spoke holes in the rim bed are easier for maintenance and spoke replacement that’s all.
10% 🤔 honestly that’s a hard one aa 18/18 is road wheel hub.
Personally Inwould ask peter from XM CarbonSpeed myself.
24mm inner for me would be ideal with maybe a 30mm but it’s persanle preference.
What frame do you have my SL8 is ok for I believe 32c tyres. So my 25mm inner width rims I have the 28mm tyres sizes 31.70 and there is still 5/6mm either side.
-
Will ask Peter, thanks.
I have a Canyon endurace cf sl 8 disc from 2021.
I currently have dt swiss E 1800 SPLINE db 30 with 22 IW and 32c Michelin Power Resistance (tubeless). I have rooms but wondering if 26 would fit.
Does peter offer 25IW ?

What Size tyres does that frame support?
According to what I have found online it’s 35mm
26mm with a 32mm tyre would probably come out to maybe 35mm.
I would contact Canyon to confirm clearance and I would measure the clearance on the frame myself.
XM from what I’m aware of don’t offer 25mm
-
Even with 26 IW, the 32c tyre should fit the frame, even if coming out at around 35,5mm. Even if the bike has 35mm tyre clearance. 32c tyre will be a bit lower as 35c, so would come more to wider parts of the fork & chainstays. And 35mm clearance with Canyon still means at least 4mm space on every side to the frame when having 35mm tyre mounted.
-
I have checked with Canyon, max clearance on my bike is actually 32mm.
The person said and i quote "I am pretty sure 26IW won't fit"
He also said that 24 would likely not fit.
I read lots of different thread saying 35c fit on Endurace on that years (2019 to 2021).
According to chat gpt, the 24IW with my tyre would measure 33 to 34mm mounted.
Is it safe to go for the 24 ?

I wouldn’t rely solely on advice from others when it comes to tire clearance—it’s best to measure directly. Grab a tape measure or, ideally, a set of vernier calipers and check the actual space between your fork blades and seat stays.
For reference, my SL8 has a manufacturer-stated max clearance of 32mm. I’m running 28mm tires on 25mm internal width rims, and they measure 31.7mm with calipers. Even then, I can just fit a 5mm Allen key between the tire and the frame at both the fork and seat stays. Based on that, I wouldn’t go wider than 30mm on this setup.
I’ll measure the clearance on my 24mm internal width rims with 28mm tires (which usually come out to around 30.7mm) sometime this week. But based on the numbers, I expect around 6mm of clearance.
Bottom line: measure your own frame’s clearances before committing. Manufacturer specs are conservative, but they’re there for a reason—especially if you ride in wet or muddy conditions.
Plus a set of Verniers are a good investment and don't cost much to buy, cheaper than buying a set of wheels that don't fit!

hi Sander, is a 26 internal channel with 28/30 tires risky in your opinion on the X68? is it too much at the limit? I have to decide that I am looking to buy a 50mm carbonspeed 24/26. I have the frame in my hand, but not the wheels. only you can give me a concrete answer.
thanks a lot

I was just about to reply!
My 28mm tyres measure 31.7mm on a 25mm internal width (ID) rim, and 30.7mm on a 24mm ID rim. Based on that trend, I’d expect them to come out around 32.7mm on a 26mm ID rim, which should still be fine.
That said, tyre width can vary quite a bit between brands—some labelled 28mm might actually measure closer to 29mm or more. Personally, I wouldn’t risk going any bigger than 30mm measured unless another forum member has successfully run 32s on a 26mm ID rim with similar frame clearance.
For reference, my 28s on 25mm ID rims (measuring 31.7mm) leave about 5–6mm clearance on the fork. I used hex key to measure this gap by the way

I ordered a set but with CX-ray spokes. Will be quite a few weeks before i receive them though.

thanks glepore for your feedback. what is the biggest advantage that the 26 channel has? I would be curious to try them. even if I am sure that I will not go beyond 30mm. I come from a use of campagnolo hyperon with 22mm tubulars wheels for rim brakes. I start pedaling again after 10 years of nothing.
I know, an ice age ago
-
The 26 internal is really just to allow the wider tires to have an optimally rounded profile. Really, 30's and 32's. Anything say 23-26, and 26 is pushing it. Peter didn't have his 24mm internal width rims when I ordered mine, which would have been slightly lighter and fine with 30-32's as well.

Hey guys, just a quick one — this is the 16-spoke front hub from XM Carbon Speed, coming in at 90.5 grams.
Peter mentioned there’s still some testing to be done, but it could be available by the end of the month. I didn’t ask directly, but if anyone’s looking at wheel builds, you might be able to pre-order the hub.
Compared to the 18-spoke version, which weighs around 91–92 grams, the hub itself only saves about 0.5 to 1 gram.
But since you’d be running two fewer spokes, you could save an additional 4 to 6 grams, depending on spoke type.
So overall, you’re looking at around a 5 to 7 gram saving on the wheels — not huge, but every bit helps.
Also, for those still waiting on hidden nipples: as I mentioned earlier in the thread, I spoke to Peter about this. Stren currently holds the patent for the system used in Scope wheels. XM Carbon is working on developing their own hidden nipple system, but at the moment, there’s no set timeline for when it’ll be ready. Just something to be aware of — it is in progress.

Guys. We will attend Eurobike 2025, our booth no. is Hall 11.1 A72. Welcome stand by and say hi
We will release new gravel rim D53TU-41 as attached by then, hooked 53mm depth 32.5mm internal 41mm external
Peter gave me the opportunity during (or shortly after) Eurobike to keep a wheelset with the new rims and titanium spokes in Germany for extended testing. I'll be preparing a review over the next few weeks — if you have any input or specific aspects you'd like me to cover, feel free to reach out.
For reference, I'm currently running a Zipp 303s on my titanium gravel bike (not the XPLR version, so the comparison has its limitations). I’ll also be comparing the wheels to Peter’s road bike wheelset with carbon spokes for additional context.
Disclaimer: I purchased the wheelset at a discounted price, but I’m committed to writing an unbiased and honest review.

Defo better value for money than the THM frontals bars I have fitted to my SL8 ;D ;D

I am currently thinking about ordering a wheelset from xmcs and am currently indecisive about hub choice. Whats the experience with their inhouse hubs regarding reliability and replacement parts? Are parts easily available or would you upgrade the hubs to some brand name?
-
They are sourcing hubs neither from THR nor from H-works. They offer whatever in-house hubs (with ratchet) or dt swiss. Zero details. Any questions about schematics/replacement/compatibility were ignored.
-
I think i read somewhere in this thread, that you can replace the ratchet mechanism with dt swiss. But i am not sure about the freehub?

Thanks for the video. I was about to order this from Peter but I was quoted 60$USD for shipping… it is quite an expensive handlebar without spacers and mount. The Tavelo is nice as well but people complain on how hard it is to pass the cables which is also making me hesitant. Please do a review once you have actually mounted it. I am now hesitant with BigRock skyline II which can be found for 200$USD on TaoBao.

One short ride so far, so can't provide any definitive feedback. Imo they certainly look nice. Got a couple of big rides scheduled this weekend so will get put through their paces then.
Separately so glad I found this forum, learnt loads, found loads of nice parts and having replaced all my rim brake bikes with this one, my recently built up R088 and Longteng 268d (currently building), I'll have 3 bikes all setup for different riding types or weather for a cost I wouldn't have been able to justify on western brands.

Had my first long ride with Peter's wheels and they are amazing! Loved the hub sound. Can't recommend enough! The whole process was really easy and they arrived in the given estimated time.

Does anyone run 28c tires on 26mm internal rims?
Yes. I am running 28mm Continental Grand Prix 5000 on 26mm internal rims. It measures out to 31.1mm
I don't sorry. According to the ETRTO, it can be dangerous.
I personally don't have any deep knowledge on the topic. At least the XM CS Website states, that the rim is compatible for 28C-45C. I personally don't have any issues with my setup.

Communication-wise, I'd say it's pretty terrible.
I ordered wheels with carbon spokes, paid on July 10th. I received a PayPal notification that the payment had been made, but nothing else.
I don't know, an email to confirm they'd received the payment, a thank you for choosing xmspeed, and the build time. Nothing.
They don't respond to Allen's email. I asked Peter for information before buying them, and he responded fairly quickly, with a rather hasty response.
I read about excellent communication, but in my case, it was pretty tragic.
I'm giving them negative feedback.
p.s. On July 29th, I made a payment of $1,000 to a name called XM Carbon Speed. I'm not entirely sure if there's a spoof website behind it, and I just clicked in the wrong place.
-
While I appreciate your frustration I think Peter is really up against it at the moment with orders and his nipper is due to be born this week. I'm sure it will all come good for you

If Peter is the only one who works at xmcarbon speed, and makes the rims, assembles the wheels, puts them in a box, ships them, handles the correspondence, marketing, etc. etc. then I'll keep quiet. But what company are we talking about then? He must have a couple of collaborators who are behind a computer, right? And what do these collaborators do during the day? It's the wrong method, communication is lacking. I'll leave aside the discussion of frames and cranks always branded xmcs, which are present on this forum with photos and prices, but don't exist on their website.

On my last ride, I noticed that my rear wheel was starting to run sideways. (see attachment)
I've been riding this Wheelset for about 600km.
The setup features D50CU-33 T1100 rims with Pillar Wing 20 spokes.
Have the spokes settled again and do they need to be readjusted, or is there a problem?
There's no visible damage and I haven't hit a pothole.

Probably a sloppy build, should just need a truing

Firstly thanks for your emails, inquiries. But if possible please do not send emails to both me and Allen, that may confuse us and make your order more time to take due to misunderstanding or ineffective communication between us. Since we normally take care of personal direct clients of ourselves who contact me only or Allen only, and Allen is in charge of all direct orders on our website xmcarbonspeed.cc, my email is there, my WhatsApp is there, you can get in touch with me any time if you had any questions.
Secondly I just had my newborn yesterday, it has been crazy busy time to me recently. So it would be better contact me via WhatsApp this time period. Allen has been affected by my family business too, He has to take more time on our company business. I don't have many collaborators currently because I just trust my men who do only right things. Please give us a little bit more time and be a little patient, your order has been arranged correctly for sure. Sorry about less communication from Allen.
Thirdly yes we are making many items and our old customers know that we haven't listed everything onto our website because many of them are new items, we are factory and we need to guarantee the quality first before we list them officially onto website.
Thanks for your understanding, and again, sorry about the inconvenience.

Secondly I just had my newborn yesterday, it has been crazy busy time to me recently. So it would be better contact me via WhatsApp this time period. Allen has been affected by my family business too, He has to take more time on our company business. I don't have many collaborators currently because I just trust my men who do only right things. Please give us a little bit more time and be a little patient, your order has been arranged correctly for sure. Sorry about less communication from Allen.
Thirdly yes we are making many items and our old customers know that we haven't listed everything onto our website because many of them are new items, we are factory and we need to guarantee the quality first before we list them officially onto website.
Thanks for your understanding, and again, sorry about the inconvenience.
Hi, I also placed an order on the 10th from the xmcarbonspeed.cc website. I didn't request anything special, I selected the wheels I liked, and today I received an email informing me of the shipment.

Congrats Peter!
Folks need to remember that there is a human side to the business, not all of the companies we deal with are conglomerates with a giant marketing staff. Part of the charm.

Thanks, mate. Don't worry, we spend more money and effort than most of our competitors' companies on development, new molds and attending kinds of bicycle fairs, we won't be that silly to disapprear just due to some retail orders. Actually many clients/ members here know my goal on carbon bicycle career. Anyway, thanks a lot, guys, for your attention and supporting.

Clincher/tubeless ready
T800 carbon
UD Matte
Depth: 40mm left
Internal: 26mm
External: 34mm
No access holes, external nipples
In-house hubs 24H/24H 36T rachets steel bearings center lock straight pull for 100*12/142*12
Shimano HG Driver
Sapim CX-Ray spokes
Sapim self securing brass nipples
So I did a ~800km bikepacking trip on these wheels setup with 44mm Tufo Thundero HD's and they were fantastic. With luggage all loaded up my gravel bike was ~17kg, my weight 90kg so system weight of around 107kg. Mixed gravel and asphalt, maybe 40/60 split. I really like the feel and had no problems. Next week I will hopefully do another trip with the 50mm deep version of this wheel with road tires, will report back.

How much those thunderos measure on this rims
-
On my last ride, I noticed that my rear wheel was starting to run sideways. (see attachment)
I've been riding this Wheelset for about 600km.
The setup features D50CU-33 T1100 rims with Pillar Wing 20 spokes.
Have the spokes settled again and do they need to be readjusted, or is there a problem?
There's no visible damage and I haven't hit a pothole.
given the very distinct buckle in a single spot i might hazard to guess that an aluminum spoke nipple has cracked at its shoulder (happens to the best of wheels). if you lightly feel the spokes at the location of the buckle you should be able to find the one spoke that's untensioned and only held in place because of the remaining part of the nipple holding it in the rim.
if that is the case it's an easy fix in the grand scheme of things but a bit of a faff if you're running tubeless and have to empty sealant, remove rim tape and re-tape the rim after fix.

This is exactly the configuration I want to order. Is there anything that can be improved in this configuration, or are you going to order all the highest specifications available from Peter? Can you let me know the final cost of this configuration?
-
These aren’t my wheels, obviously, but they represent the highest specifications currently available in this configuration—T1100 carbon paired with the new 18/18 hole spoke hubs.
Best to WhatsApp Peter directly for pricing, but last I checked, they were around $950 USD (excluding shipping).
+86 182 5080 8148
The only update from XM CarbonSpeed at the moment is that they’re developing a 16-spoke front hub and exploring hidden nipples for carbon spokes. However, there’s no confirmed release date—you’ll need to ask Peter, though it’s unlikely he’ll give a timeline since testing and development take as long as they take.
-

As sander said these are pretty much the highest spec Peter does right now. My other set are the same but 50mm with 20 hole spokes. With 1180g. Went with the new hub to save a few grams.
Price was $980 plus shipping. Need to get them set up but my 50s are absolutely awesome. I’m hoping the 65mm will be be bit quicker for Flat riding.
-
And finally, my wheels are being shipped tomorrow!
Originally, I wanted titanium-colored hubs, but Peter is busy with Eurobike and wouldn’t have been able to send them out until afterward because the hubs needed anodizing. So, I was offered black hubs instead — no big deal since black was the original spec, but I had changed my mind.
New 18- and 18-hole hubs
UD paintless finish
CS-D50CU-31 disc brake carbon road rim: 50mm depth, 33mm wide, 24mm internal width
CS-D65CU-31 disc brake carbon road rim: 65mm depth, 33mm wide, 24mm internal width
Spoke holes on rim bed
5mm carbon spokes made from T1100 carbon
I was told the weight would be 1200 grams, but it came in just a smidge under at 1196g — beating my old CRW Gen 1s at 1280g and even the new ones at 1250g! 😄
Now comes the painful wait as I watch the parcel tracking slowly make its way from China to the UK… hopefully, it arrives quicker than expected! :(
How are these holding up for you? I'm 75kg and trying to pin down which spoke count to pick. I'm getting these same rims. I was considering 18 in the front and 20 in the rear. Had no idea 18 in the rear was safe. I ride in the road, but there can be gravel in the road occasionally and I'm worried if I hit a pot hole the rear will break with only 18 holes and all my weight on the rear. What do you think?
How is the UD paintless finish holding up? Saving 40 grams of rotating weight is tempting, but I'm worried about chipping the carbon. My old painted carbon rims get chips in the paint. Maybe if I have no paint it will chip out the carbon and epoxy?
-
I have ordered a wheel set from Peter.l at XM Carbon speed and a few hundred miles in I’m very satisfied!
Ordering process was fast. Delivery was even faster to the Netherlands.
-
Forgot to add the wheel description:
It weighs around 1270-1280g/pair:
D50CU-33 T1100 rims 24/24H UD paintless
R280 in-house hubs 24/24H 36T rachets TPI steel bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
Sapim CX-Ray spokes
Sapim self-securing aluminum nipples
From the inquiry to the delivery it took exactly 3 weeks.
-
Have seen orders with the new 16H front hub coming through, anyone pulled the trigger?
-
I reckon you refer to the weightweenies post?
That was me.
Lead time is still 25 days until shipping so seems like production did not start yet.
-
Have seen orders with the new 16H front hub coming through, anyone pulled the trigger?
I put in a pre order in for a 16H front hub 18H rear hub wheelset. Rims are being made and the wheelset will be sent out when and if the front hub passes testing
50mmx33mm front
65mmx33mm rear
5mm T1100 spokes and rims, 54T hubs + steel bearings and UD paintless
-
Can't wait to see what the 16 spoke with 5mm spokes will look like. I think they'll look amazeballs!
-
Got a nice surprise today
-
Mine shipped last week, so the 16 hole hubs passed testing. Should be here soon. Curious how the front wheel will feel with only 4 spokes on the non braking side
Edit: They arrived yesterday. Review impressions coming soon

I‘ve been riding
D50CU-31 T1100 rims 20/20H UD matt
Black colour in-house hubs 20/20H 54T sprockets TPI ceramic bearings centre lock straight pull for 100*12/142*12 with Shimano HG Driver
5.0mm carbon spokes
since mid/end of June.
Now they're starting to make noises. A quiet creaking noise when I pedal. After checking the crank and bottom bracket twice, and two different chains and cassettes, I've ruled out the Shimano drivetrain. Today I fitted a different rear wheel and I couldn't hear it anymore. I've taken the freehub off the rear wheel and, when cleaning the components, I noticed metal shavings. It was on my cleaning Paper and Fingers. You can also see wear on the pinion gears. I haven't disassembled the freehub any further as I don't have any tools at hand.
I'm surprised to notice this after such a short time. I wrote to XmCarbonspeed Right now. I am excited how they react.

Thanks for youfeedback and sorry if I didn't reply your email in time 5 hours ago, time difference anyway. I think I'd better reply here directly, others can see how we deal with this as well.
If the roads there are dusty not very good, even you ride with original DT Swiss hubs, you need to do proper maintenance after decent miles as well.
Please clean the rachets and use new grease, if the noise is still there, we can send you new rachets, even new axle and bearings if you think needed, as soon as you could confirm what the exact problem is, we would handle that for sure.
And we will upgrade the rachets with titanium material to make them with better performance, we are testing them now.
-
Thanks for the quick reply. I got to work on it over the weekend. I thoroughly cleaned the pinions with brake cleaner and regreased them. After a longer test ride, I can say that the freewheel was definitely the cause of the cracking. I'm wondering how long the cracking will stop. If it only lasts 1500km, as before,I'd have to repeat this cleaning procedure every 2-3 months. Since there was already considerable wear on the pinions, I suspect the wear will continue. I hope you can see in the pictures how small metal parts are missing from the surface of the pinions.

Just confirmed a DT Swiss 350 freehub will fit into XMCS Hubs
-
So they offer three different hubs: 20/20, 18/18 and now a 16/16? Is there difference in the ride feel besides the weight? Does the rim flex more with less spokes? Is price the same for all hubs?

21/21, 20/20, 18/18, and single front 16H hub option, no 16H option for rear wheel.
And only 21/21H hubs wheels on promotion with discount, 20/18/16 hubs wheels won't be discounted this year due to the effrot and money on these new development hubs, and they are obviously not same price.

Peter is releasing a set of titanium spoked wheels...
-CarbonSpeed CS56 Pro - More on this "pro" line of wheels at a later time.
-50mm / 31mm ext T1100 rim 24mm internal
-60mm / 31mm ext T1100 rim 24mm internal
-Titanium spokes with Sapim self-securing aluminum nipples
-New version in-house hubs 24/24H
-54T ratchet
-TPI ceramic bearings
-Weight 1250g before tubeless tape.
These are loosely intended to compete against the latest ENVE 4.5 SES Pro wheels. Now, I'm not the titanium police. So we won't go into the ideology, pros, and cons of using this materal for spokes. But just know they are available if ya wanna partake. Future details and pricing coming soon.
Just got my hands on the current Scott Foil RC Pro. Figured these wheels would make a lot sense. The full build with pedals, cages, and computer mount is somewhere around 6.9kg all in.

Someone in the thread wrote that the rear hub/freewheel sound is quite loud - with the "own hub system" that supports carbon spokes.
Peter told me that if I want to go with carbon spokes I will have to got with their own hub system - DT Swiss, Novatec, Extralite won't work.
Can someone record and upload a video that shows the noise and share it here?

Watch some YT videos from Patrick Lino. He has this wheels.

Hi all,
short feedback on my wheels received from Peter a couple of weeks ago and mounted on a Tarmac SL7.
They are 50mm front / 60mm rear (D50CU-31 and D60CU-31), 54t ratchet, 3.8mm carbon spokes, 20/20H, UD paintless, rim 24mm inner/31mm outer so perfect for 28mm tyres. With this rim, my 28mm tyres have 30mm width.
One of my requirements when getting those was not to loose in comfort vs my previous 50mm wheels with metal spokes, as well as good cross-winds stability (Peter recommended 3.8mm spokes for that purpose).
Upon receiving them, I started regretting that I did not get Sapim CX-Ray spokes and 36T ratchet (for long-term usage - I spent too much time documenting myself ;D), but after having rode them on 2 occasions, I am really happy with my choice:
- I did not loose in comfort with the carbon spokes and higher rim profile
- I see many people say that 36T ratchet is very suited for road use, but I actually find the 54t really nice to ride....it makes for a very comfortable ride, i.e. when re-starting to pedal, the transition to the hub "biting" is very smooth, I really like it
Aside from the ratchet and from not losing in comfort, the main difference I can feel is the acceleration vs my previous 1590gr wheels. These feel like they respond right away.
But otherwise, I'll be honest and say that I did not feel huge differences....but when checking my Strava, the data tells me otherwise ! I'm not in great shape currently, yet I'm having the same top speed and average power than during the season....I can't wait to get even more acquainted with those wheels ! 8)
That's my 2cents ;) Happy customer, good job Peter and keep it up !

I got a set of wheels with 54t ratchet, and to be honest, the volume is much lower than I expected....54t makes a higher-pitch noise compared to 36t.
Also, you can influence the volume of the noise by adding or removing grease....so I would not worry about the noise level on XM Carbon Speed wheels...
-
Any thoughts on the 21/21H hubs with the side entry spokes? Anyone seen the spokes turning or potentially popping out under load?
-
OK guys just an update on my 50/60 XMCS wheelset. They came out of true. Rear wheel was only slightly out of true, the front had a huge death wobble, so far out of true that the bike was not rideable. I sent Peter a few videos and he agreed to pay for a local mechanic to true the wheels.
Not his wheels, not his problem, but Ben Caden of CADEN WHEELS gave me 3 hours of his time today to troubleshoot these wheels. He shot video of it all too, so expect that to be up on his channel soon (apologies in advance for being so flat in the videos, I had a big night on the drink last night!).
OK so this is what we found:
1) The wheels were not far off being true without the tyres on them. IE: The wheels are not strong enough, and with 60 psi in the tyres they go out of true.
2) Ben trued both wheels to perfection, then he had the idea to try clincher tyres instead of tubeless tyres as he said tubeless tyres create much more pressure. He stocks and backs Maxxis High Road SL tyres, a tyre I've always been curious about more for the light weight, but despite poor rolling resistance tests Ben says they roll fast so I'm more than willing to take his word and try them out.
3) Ben suggested a 25C front and 28C rear, but I thought I'd go 25C front and rear as I only ride this bike at Centennial Park (very smooth surface). Tyres went on SO much easier than the tubeless ready Aero 111 and GP5000 TT's. Tyres were inflated to 60 psi and both were put back on the trueing stand and guess what? Both wheels were quite true, not perfect, very slightly out of true, but no more huge death wobble on the front wheel.
4) Some more findings: You can quite easily squeeze the XMCS wheels with your fingers and see them deflect, Caden's wheels on the other hand I was not able to squeeze in at all, though he grabbed his wheel off me and squeezed very hard and said there still is some give if you squeeze hard enough. The rear wheel started making noises akin to Ocean Gate. IE: Carbon cracking noises when pumped up to high pressure to set the bead, freaky stuff, but the noise did stop. Make of that what you will.
5) Ben let me know that these wheels were not bad, and that he's seen worse from China. Some of the bladed carbon spokes aren't completely straight, but they use a T junction at the hub and cannot be turned at all, so nothing can be done to adjust them.
6) All this information was passed on to Peter, and he's offered me another wheelset at a heavily discounted price, but I fail to see how another XMCS wheelset would be any different (except for maybe better finishing quality which he's suggested was because I went for a custom polished finish vs. UD matte).
With the new tyres my Cervelo S5 now sits at 6.18kg's which I'm pretty happy about. I'm a little bummed the XMCS wheelset experience was much like the experience I had with the XMCS chainring (which is in my parts bin), but in this case I'm going to at least see how these wheels go before putting the ENVE 5.6 rear and Roval CLX II front wheel back on.

A - 1) You can try to inflate 110-120 PSI on our T1100 rims, All our rims should be tested on this at 120 PSI before moving to finish process. If only 60 PSI, I think the problem should come when they were polished, and some resin on the rims even affects the rims finish and roundness too, so if some resin attached on neccesary area was removed, the rim might get defective.
A- 4) And T1100 rims layups are super light layups, I tell everyone who has asked us before, they can't use their finger to squeeze the rim lateral, as more as you squeeze, the rim layups would get affected then they will be soft. Are Caden's wheels so light too? This is why many big brands don't want to make super light layups rims.
Random probability problem, things even happen on any big brands, as I said, we don't pick any items specially for any clients, even when we send our products to those YouTubers for testing and reviewing. We can take care of these problems very well in any way as you want. At leaset, before your this kind of pertinent review, no one else has mentioned same problem before, so I am still quite confident on our products, but yes we need to some work on the glossy paintless finish details, and the details on building wheels before shipping out. Thank you so much and sorry about your unpleased experience.

I've been updating the process of getting the wheels trued on Weight Weenies forum, but forgot about this thread too.
TLDR: Peter offered a new wheelset in the same specs but in UD Matte finish and I cover postage, to which I thankfully accepted.
Peter has been VERY responsive throughout all of this via WhatsApp and just confirming that I am very happy with the resolution and as I've mentioned to Peter I am now once again confident in his brand (and service).
Peter also has confirmed that he himself will inspect the wheelset and pack them himself too. I will, as usual, report back here and elsewhere on the new replacement wheelset with photos and more when they arrive.

What wheelset would you guys be recommending for the following case:
Frame clearance between 32mm and 35mm, even though I plan on running tyres with a width of ~32mm. So I could basically go with 24iW and 30 or 32mm tyres or with 26iW and 30mm tyres. Depth should be between 60 to 65mm as I will be mostly in flat-land conditions :) Visually, I am aiming for a nice, clean transition between the tire and the rim.
Any recommendations?
-
The 32 mm will blow up to about 34 mm on a 28 mm rim. Thats what I am running (65 mm depth, 34-28)

FWIW, I have CS-D50-CU-33 rims (26mm IW), which I use with 32mm GP5000 tube-type clinchers. Surprisingly, they only measure out to 33.3mm at 65psi.

33.4mm on GP5000 tubeless ready over here. 28c GP5000 clinchers stretch out to 31mm

So…24 or 26? Still a bit unsure. Anyone using 30mm on an 26 internal rim?

The smallest approved tire width for 26IW is 35mm, according to ETRTO standards. With that being said, do what you want. I’m running 32s, but I wouldn’t run 30s, although I know others on this forum are.
-
Josh Poertner (ex Zipp 404 wheel developer) runds a 32mm GP5000S TR on 3T Discus wheels which are 29i.
If the wheels are hooked, he believes minimum tubeless tyre size = inner rim width + 3mm.
-

I run 30mm Pirelli P ZERO™ Race RS TLR SPEEDCore on the IW26, and at 65 PSI they measure pretty much exactly 33mm.

I am about to order a pair of D65CU-33 T1100 with 5mm carbon spokes.
However, I am unsure whether to go 16/18H, 18/18H, or 18/20H.
System weight is 90 +/- 2 kg depending on day, pure road usage.
Any input?
-
aren't those steel spoke hubs?

Similar thoughts, although I am 10kg lighter (80kg) and going for D50CU31 T1100 w. 3.8mm spokes... not sure about the spoke count config :) 16 spokes in the front looks amazing though...

Leaning towards 16/18H…
For comparison, Farsports rates their 18/18H 5mm spoked wheels at 120 kg.

I've sent an email to Peter ,waiting for his feedback.
Looking for a wheels with rim CS-D50CU-31 (marble finishing) laced with hub r248 grey/titanium color 24holes and ceramic bearing.
I'm not sure regarding which spokes will suits me better.
I'm a (quite) powerfull rider at 87kg and i would like to have a wheelset under 1350grams if possibile.
Any suggestion between carbon spoke (max 3mm Wide) or steel or the new one in Titanium
Thanks

I'd go steel or Ti if you regularly ride over 2 hours. I have 16H/18H 5mm carbon spokes and the vertical stiffness gets to you even on 32c tires. If you're racing, you'll probably like the vibration feedback

Anyone that can show me a picture of the ceramic tpi bearings?

Let me give props to these wheels from Peter, on recommendations of our dear Serge ;)
Couple of months ago I was riding my bike on a slight uphill (2-3%) and was going relatively fast, around 37km/h and I noticed a construction line/tear across the whole road (the cut-out in asphalt to put cables and stuff across), but was completely assured it's only around 20-30cm wide, so I decided to jump it, only too late to notice the thing was at least 60-80cm wide, so I SLAAAAMEEED my rear wheel so hard on the mere edge of that gap, thinking it will CERTAINLY be some problem, broke spoke, frame, rim... Pulled up right away, and was amazed it survived without a single scratch, crack or anything else.
tldr... I'm 85kgs, riding at 35+km/h slamed a "cheap chinese wheels" and they survived. One personal experience I will remember when ordering another wheelset for another bike.
wheels are 50mm/26/33 T800 rims, sapim cxray, xmcs hubs. 24spokes. 1400ish grams.

Hi! Do we have product info/specs on the various hubs that are offered? I went through the whole thread, and learned that their in-house options are:
- 21/21H
- 20/20H
- 18/18H
- 16H front hub
For each hub, I was interested in learning about:
- weights
- colors (silver/Ti, black, other?)
- ratchet options for each rear hub
- freehub body options (HG, XD, Microspline, campy, other?)
- straight pull only?
- photos /dwgs
Lastly, what non-carbon spokes are available? what is the baseline spoke? and what are "upgrades" (cx-ray, cx-super, pillar, etc)?
-
Hi, referring to the post above. I have wheels from Peter since april, 35 mm rim, external 33 mm, 26 mm internal, XDR hub, 1095 g, simply the best! I have Conti Archeotype 30 mm on it, and that set is amazing! Rode almost 10k km, no issues, wheels are stiff, comfortable, no problems! I tested them on:
1. climbing during Ultrafondo The Everest so more than 260 km and more than 9200 m up during one event,
2. on Mallorca
3. some local climbs and our Polish mountains, and descents were I felt very confident.
All of that with 30mm tires and I really can notice the difference! Fully and 100% satisfied and happy!

My 2nd set of XMCS wheels came in the mail today and weighed in at 1168g for the set.
No quality control issues at all. Super smooth edges both inside the rim bed and out. So happy to have my prefered Aero 111 front and TT TR rear tyre setup again. There were no issues with fitting tyres without levers and both wheels run true with tyres inflated to 60PSI.
I actually think the standard UD finish looks better on the bike too!

Looks great, weight is interesting. Can you share the specs of the wheelset?

50/60, 24mm IW, 5mm spokes, 16 hole front, 18 hole rear.

50/60, 24mm IW, 5mm spokes, 16 hole front, 18 hole rear.
Beautiful bike, may I ask what the outer width is? 16/18 looks better to me. He quoted me 24/24.

One question on the XMC in-house-hub and Centerlock disc rotors: Is anyone using internal lock rings?
I am currently on external and look for new disc rotors.

I'm using the internal one, no issues. I have one from kogel and one super light from cheaser from ali.

Anyone using the current promotion 21h hubs? Any experience or concerns since it is the side loaded spoke style

are those UD matte or UD paintless wheels? hard to choose when the glossy wheels look amazing as well
-
50/60, 24mm IW, 5mm spokes, 16 hole front, 18 hole rear.
Why did you pick 5mm spokes? I want almost the same config, but can't decide whether to go for less-stiff superlight spokes, or 3.8mm or 5mm haha! (5mm look the best by far)
-

UD Paintless.

Looks like XMCS's shopping cart is broken for me after trying for a couple of days. Anyone else having issues placing an order?

Contact Peter direct over WhatsApp- I did that with all 3 of my purchases.

I rode them for half a season this year without any problems (~ 2.000km) —even though I'm unfortunately not exactly lightweight (80 kg+). Running great!
For a new set, I would invest the additional cost for the new hubs, even if it's just a "feeling". If you're interested in a swap / would like mine, let me know. ;)
-
How many spokes do I need? I see options between 16 and 20. How do I choose and what's the benefits and drawbacks of each (obviously weight is one).

I saw a nero show video a while back, where they talked about a Magene wheel that lost its hub because one of the spokes broke. Is that a possibility with the 21/21H hubs? It’s probably a technical possibility, albeit a rather small one?
The newer 20/20H (and lower number of spokes) hubs do not have that problem, I assume?

the 21/21 hubs yes....possible if a spoke broke or de-tension it could potentially slip out the side because it is open.
20/20 or others (more or less spoke) that has the through hole design would be the "safer" ones if you are talking about that use case.

Weight, aero, aesthetics, and safety. I'm working on a long term review of the 16H/18H setup and so far they're solid. I've bombed them down mountains and hit a crack hard enough to snap the clips off my bike computer. Still straight, no broken bones. No major issues with the wheels so far. I also packed them tight in a bike box to fly them from San Francisco to Toronto and back. Held up to to baggage handling and a TSA inspection
I'm going to ride them until the end of the year until I make the proper review, but so far I'm confident in their safety for riding, not confident in the durability if you want to fly with them, or get in a crash, and don't recommend carbon spokes for long distance riding unless your fit is totally dialed
Get T1100/16H/18H/34mm if you want the best you can buy for crit racing or you just want to go fast on rougher roads. If you care about durability or value, get a lower grade carbon. You can deflect the T1100 rims by pushing the side walls with your finger. T700/T800 is much more durable
If you ride 50 miles plus, stick to steel or titanium spokes. Pick Ti if you want the very best for long distances. Pick steel if you want 99.9% of the benefit of Ti for a lot less money
Peter is great. I don't think I'd buy my next set from a western or Chinese brand for my next set. OEMs like Zara at Zen and Peter with XMCS don't seem beatable if you have better uses for $2,000 than a brand name + excellent warranty, or want better specs with good enough warranty care
- My Elitewheels de laminated, ending my 230 mile weekend ride 20 miles from the finish line. Elite told me to kick rocks, I posted about it, and now they want me to delete my story to get my warranty replacement
- A western wheel brand would have instantly replaced the whole wheel or paid to replace the rim, but that cost is built into the price alongside pricing power for branding cache. Western brands are also 5 years behind the Chinese because the actual manufacturing know how is in China, and western brands are paralyzed by litigation hell
- When @JustinFox had an issue with Peter's wheels with a custom polish finish, he immediately paid to re-true the wheels, and offered a heavily discounted replacement without polish when that didn't fix the issue. An immediate rim replacement would probably have made more sense for both parties, but the discount likely would have cost Peter around the same amount
- - The rims are only around $180 per, I'd guess they cost Peter $100 each to make, labor to lace the rims in Australia would be around $100, guessing shipping is around $75, so $375-$400. I'm guessing his discount for a new wheel set was around that much
- - When Justin posted his story, Peter replaced the whole wheel set, and presumably didn't condition it on deleting his story. A full wheelset replacement is pretty unexpected direct from an OEM considering the price point
I looked for the cheapest semi comparable option to Justin's from Zipp. Here it is:
https://www.competitivecyclist.com/b/zipp-454-nsw-carbon-disc-brake-wheel-tubeless
- Zipp: $3,396.38 shipped to my door
- - Mine from Peter (T1100 50/65x34mm 16/18): $1,060 shipped to my door
- Mine were fine, but if Justin's wheels are anything to go off, Zipp could have better wheel balancing out of the factory, or Peter's could just have had too much resin polished off his rims, throwing off his wheel true-ness when a tire is inflated. I'd imagine the polished finish has been axed anyways
- 53mm - 58mm depth vs 50mm and 60mm these likely have around the same average depth
- 27.8mm max external width vs 32.9mm
- Zipp also has a wavy rim profile that should help in the crosswinds at that depth, but wider rims do a lot to reduce cross wind instability as is
- - If I could go back and buy my set again, I think I would just go 65mm front and rear. 50mm is no problem at least at a 34.25mm width, I'd guess 65mm depth is fine as well. Justin's are only 1.35mm narrower, so I'd imagine they have similar stability
- 1358g claimed weight (1500g actual weight (1509g weight in by Pat with valves)) vs an 1168g actual weight on Justin's.
- - Peter quoted me 1255g-1265g for T1100 50x32mm/65x34mm 20/20. I went with 18/16 spokes (-18g) but a thicker 34mm wide front rim (+10g), so I expected 1247g-1257g, but the actual weight was 1229g. That's 18g lower than the lowest estimated weight, and 23g less than the mid point estimate vs 142g over estimate with the Zipp wheels
- - Also keep in mind that 1500g weight is while cutting out the hook bead which would add 30g, and make the wheels significantly safer
- Only steel J bend spokes in 2025 vs steel, carbon bladed at several depths, or titanium
- Cheaply made
- - Hookless trash
- - 24 spokes front and rear with the same rim and same lacing pattern. Incredibly lazy or ridiculous cost cutting on a premium wheelset
vs
- As cheap or expensive as you please
- - You can go down to T700, spoke holes, steel bearings, steel spokes, 24/24 hubs, for a few hundred dollars(Wait, I think this is just the Zipp wheel, except with a hook so you don't lose your teeth), all the way up T1100, ceramic bearings, new 16/18 hubs, bladed carbon spokes, no spoke holes, custom stickers, for 1/3 the price of the Zipp wheels, and expert advice from Peter along the way
I don't feel too bad for picking on Zipp after listening to their product manager hop on the Nero show and spend a full hour spouting off dishonesty and marketing drivel:

Peter has a solid niche with a very good value proposition. I think tweaking his warranty practices to avoid any sort of purchase by the customer mid warranty would be ideal. It feels better to get a $360 of rims replaced free than to get a whole new $1100 wheelset for half off, even if you're getting a better deal when you do the math. Maybe require destruction proof when warrantying a defective rim to dissuade bogus warranty claims since there's less margin on these wheelsets
I also think proper branding on his products is an easy way to add a lot of value for many of us. I think my XMCS wheels are really cool. I paid like $50 to make some custom XMCS decals. Peter could offer nicer branding on them and it would likely cost him like $10 per set. I'd bet sexy branding could drive a couple hundred dollars of perceived value to consumers, even if it's not backed up with marketing money
I had a hard time picking between XMCS and Magene EXARs even though the specs for XMCS were better. Magene simply has better aesthetics than a plain rim and are the same price as Peter's wheels
This turned into a mini review by accident, but I've got a lot more to say about my wheels, and I still want to get some more time on them to get more of a feel for how they ride, and to see how they hold up over time. It took hundreds of miles until my ENT 2.0 showed an issue. Too many "they hold a line well, they're really smooth, I don't see any voids, use my affiliate code in the description" type of wheel reviews out there. The world doesn't need mine :D

Great ”mini” review.
What is your system weight? I guess that is something to take into consideration when running 16/18H.
I have a 58/65-33 T1100 5mm spokes setup on pre-order, went for 20/20H as I want to be able to run a 95 kg system weight.
Also, regarding going for 50 miles plus and you suggesting steel/titanium spokes instead. A fair load of my outdoor rides are 50 miles, usually 100+. What tire width are you running? I suppose that affects perceived harshness.

- My Elitewheels de laminated, ending my 230 mile weekend ride 20 miles from the finish line. Elite told me to kick rocks, I posted about it, and now they want me to delete my story to get my warranty replacement
- A western wheel brand would have instantly replaced the whole wheel or paid to replace the rim, but that cost is built into the price alongside pricing power for branding cache. Western brands are also 5 years behind the Chinese because the actual manufacturing know how is in China, and western brands are paralyzed by litigation hell
- When @JustinFox had an issue with Peter's wheels with a custom polish finish, he immediately paid to re-true the wheels, and offered a heavily discounted replacement without polish when that didn't fix the issue. An immediate rim replacement would probably have made more sense for both parties, but the discount likely would have cost Peter around the same amount
- - The rims are only around $180 per, I'd guess they cost Peter $100 each to make, labor to lace the rims in Australia would be around $100, guessing shipping is around $75, so $375-$400. I'm guessing his discount for a new wheel set was around that much
- - When Justin posted his story, Peter replaced the whole wheel set, and presumably didn't condition it on deleting his story. A full wheelset replacement is pretty unexpected direct from an OEM considering the price point
I looked for the cheapest semi comparable option to Justin's from Zipp. Here it is:
https://www.competitivecyclist.com/b/zipp-454-nsw-carbon-disc-brake-wheel-tubeless
- Zipp: $3,396.38 shipped to my door
- - Mine from Peter (T1100 50/65x34mm 16/18): $1,060 shipped to my door
- Mine were fine, but if Justin's wheels are anything to go off, Zipp could have better wheel balancing out of the factory, or Peter's could just have had too much resin polished off his rims, throwing off his wheel true-ness when a tire is inflated. I'd imagine the polished finish has been axed anyways
- 53mm - 58mm depth vs 50mm and 60mm these likely have around the same average depth
- 27.8mm max external width vs 32.9mm
- Zipp also has a wavy rim profile that should help in the crosswinds at that depth, but wider rims do a lot to reduce cross wind instability as is
- - If I could go back and buy my set again, I think I would just go 65mm front and rear. 50mm is no problem at least at a 34.25mm width, I'd guess 65mm depth is fine as well. Justin's are only 1.35mm narrower, so I'd imagine they have similar stability
- 1358g claimed weight (1500g actual weight (1509g weight in by Pat with valves)) vs an 1168g actual weight on Justin's.
- - Peter quoted me 1255g-1265g for T1100 50x32mm/65x34mm 20/20. I went with 18/16 spokes (-18g) but a thicker 34mm wide front rim (+10g), so I expected 1247g-1257g, but the actual weight was 1229g. That's 18g lower than the lowest estimated weight, and 23g less than the mid point estimate vs 142g over estimate with the Zipp wheels
- - Also keep in mind that 1500g weight is while cutting out the hook bead which would add 30g, and make the wheels significantly safer
- Only steel J bend spokes in 2025 vs steel, carbon bladed at several depths, or titanium
- Cheaply made
- - Hookless trash
- - 24 spokes front and rear with the same rim and same lacing pattern. Incredibly lazy or ridiculous cost cutting on a premium wheelset
vs
- As cheap or expensive as you please
- - You can go down to T700, steel spokes, spoke holes, steel bearings, steel spokes, 24/24 hubs, for a few hundred dollars(Wait, I think this is just the Zipp wheel, except with a hook so you don't lose your teeth), all the way up T1100, ceramic bearings, new 16/18 hubs, bladed carbon spokes, no spoke holes, custom stickers, for 1/3 the price of the Zipp wheels, and expert advice from Peter along the way
I don't feel too bad for picking on Zipp after listening to their product manager hop on the Nero show and spend a full hour spouting off dishonesty and marketing drivel:
www.youtube dot com /watch?v=jB735qrgc5E (i did this to disable the embed)
Peter has a solid niche with a very good value proposition. I think tweaking his warranty practices to avoid any sort of purchase by the customer mid warranty would be ideal. It feels better to get a $360 of rims replaced free than to get a whole new $1100 wheelset for half off, even if you're getting a better deal when you do the math. Maybe require destruction proof when warrantying a defective rim to dissuade bogus warranty claims since there's less margin on these wheelsets
I also think proper branding on his products is an easy way to add a lot of value for many of us. I think my XMCS wheels are really cool. I paid like $50 to make some custom XMCS decals. Peter could offer nicer branding on them and it would likely cost him like $10 per set. I'd bet sexy branding could drive a couple hundred dollars of perceived value to consumers, even if it's not backed up with marketing money
I had a hard time picking between XMCS and Magene EXARs even though the specs for XMCS were better. Magene simply has better aesthetics than a plain rim and are the same price as Peter's wheels
This turned into a mini review by accident, but I've got a lot more to say about my wheels, and I still want to get some more time on them to get more of a feel for how they ride, and to see how they hold up over time. It took hundreds of miles until my ENT 2.0 showed an issue. Too many "they hold a line well, they're really smooth, I don't see any voids, use my affiliate code in the description" type of wheel reviews out there. The world doesn't need mine :D
Would love to see your XMCS wheels with the decals you had made. Here is the custom decal I had made for my XMCS R01 frame from Peter.

Hi! Do we have product info/specs on the various hubs that are offered? I went through the whole thread, and learned that their in-house options are:
- 21/21H
- 20/20H
- 18/18H
- 16H front hub
For each hub, I was interested in learning about:
- weights
- colors (silver/Ti, black, other?)
- ratchet options for each rear hub
- freehub body options (HG, XD, Microspline, campy, other?)
- straight pull only?
- photos /dwgs
Lastly, what non-carbon spokes are available? what is the baseline spoke? and what are "upgrades" (cx-ray, cx-super, pillar, etc)?
I would be interested to learn the bearing sizes used as well. I'm thinking a bit about these hubs for a wheel set build or two - though I'm not sure if they could be persuaded into selling hubs (and maybe spokes) to build your own wheels with other rims.
-
Weight, aero, aesthetics, and safety. I'm working on a long term review of the 16H/18H setup and so far they're solid. I've bombed them down mountains and hit a crack hard enough to snap the clips off my bike computer. Still straight, no broken bones. No major issues with the wheels so far. I also packed them tight in a bike box to fly them from San Francisco to Toronto and back. Held up to to baggage handling and a TSA inspection
I'm going to ride them until the end of the year until I make the proper review, but so far I'm confident in their safety for riding, not confident in the durability if you want to fly with them, or get in a crash, and don't recommend carbon spokes for long distance riding unless your fit is totally dialed
Get T1100/16H/18H/34mm if you want the best you can buy for crit racing or you just want to go fast on rougher roads. If you care about durability or value, get a lower grade carbon. You can deflect the T1100 rims by pushing the side walls with your finger. T700/T800 is much more durable
If you ride 50 miles plus, stick to steel or titanium spokes. Pick Ti if you want the very best for long distances. Pick steel if you want 99.9% of the benefit of Ti for a lot less money
Peter is great. I don't think I'd buy my next set from a western or Chinese brand for my next set. OEMs like Zara at Zen and Peter with XMCS don't seem beatable if you have better uses for $2,000 than a brand name + excellent warranty, or want better specs with good enough warranty care

Love the detail in your post. I ended up ordering a set of 20/20, max spokes available. Mostly out of an abundance of precaution. Going with the 3.8mm carbon spokes. Orders a 50mm/60mm T1100 set with an extra 60mm front for flat races. I love that the outer width goes to 33mm as I plan on keeping with the 105% wheel/tire rule. From what I've read, my 28mm GP5000's should blow up to about 32mm on these rims which aligns perfectly to the rule. Got them ordered with a gloss marbled finish (I'm typically a matte guy but I originally found the marbled gloss look on the new Elite Drive ii's and really like it [The Drive ii's have a reduced hook which are a no-go for me]). It's a little bit of extra weight but, as they say, ride kit that you love and will make you want to ride more.

Hello, everybody.
If someone is interested in wheels for some "bigger" road tires. I just revived set of wheels from Peter with 28mm internal and 36.6mm external width.
I think they look pretty awesome and tire and rim combination is pretty much perfect.
I did not have chance to properly test them, but I test them just around house with some short sprints and wheels seams pretty solid.
So far pretty happy with wheels and if you want some 32mm+ tires on your road bike and you have tire clearance I would definitely recommend these rims.
Tires that Iam using are Michelin PRO5 35mm rear and 32mm front.
Weight is without rim tape
Complete wheels specs that I sent to Peter
CS-D50CU-36 (T800 version) rims
-UD matte finish (with no decals)
-With access holes in rim bed
-3.8 mm carbon spokes with t-head
-18 spokes front wheel
-20 spokes back wheel
-black color hubs
-steel bearings
-36 tooth ratchet
-
What decals is that? Just abstract enve-lookalike or replica of an actual brand?
-
kjerts: I had them made to order from reflective material. I "copied" logos from "EIE" wheels it is legit brand from Xiamen. Iam sorry to Peter :) for putting logos of other brand on his wheels, but you know I always put some reflective logos on my rims for safety and I like those logos and there is definitely bit of Tadej enve efect for sure :)

I am currently looking for wheels to replace my Elite Edge 1.0 with 65 mm rim height and 21 mm inner width.
I ride crit races.
I would like a rim height of 60-65, no more, as this is prohibited by the new UCI rules. I think 23 mm in mouth width would be ideal, as I want to ride 30-32 mm tires.
Since you can easily crash or other riders can crash into you, I'm afraid of carbon spokes because they're not so easy to replace, right?
Crits are just a bit rough 😅
Of course, they should still be as light as possible.
They shouldn't necessarily be the most expensive ones either, because the risk of them breaking during the season is naturally a bit higher 😉
I've read a lot of good things about Peter. Do you have any tips or recommendations?

T800/T1100 26/34mm Rim with Sapim spokes is excellent value for money right now and . I plan to buy two pairs for me and my friend, and they're lighter than Edges (I have the same Elites but in 50 mm).

For crit racing I'd go 65/65 with carbon spokes. 33/34mm wide in the rear and either the 33/34mm in front if you want to run a 30/32c front tire or 31/32mm if you want 28c
You can order spare carbon spokes, and the stiffness/snappiness when sprinting is mentally satisfying. I don't think I'd go ultra light carbon for a crit racing. Get a more durable grade of carbon

I had thought about this with my wheels. But using AI to make an Enve inspired logo that said XMCS. To get the effect but still show off XMCS. Never bothered going that far, I plan to leave mine blank in the end
-
Peter sent tracking info for my wheels. Excited to get them! 58mm, 16/18 spokes and very pleased with the weight! Going to pair nicely with my LC LCR018.
-

I designed a logo that I might put on my wheels when they are delivered.
-
JensenMacD: That is interesting. Did you ever got some final design that is worth showing?
Budder12: That looks pretty good. I think that X looks a bit out of place maybe if that X would be all connected, but that is just nit picking and I like it. Would you mind post vector graphic file of that logo?

I did make a design but deleted it (shame on me) when I decided to leave the wheels blank. It was similar to Budder12's but a but the X was solid.
Edit - AI saved an early version. I later made the X solid and a few small tweaks. But this was 90% there.

Now we are developing new Ultralight 20/20H hubs for carbon spokes, around 230g/pair, they should be released end of Jan or early Feb. At the same time, we are making titanium freehub for 20/20H ultralight hubs with same rachets design as Tactic hubs as well, so there will be plenty options on our hubs soon.
And we are going to do D78CU-33 same 26mm internal hooked rims 78mm depth , this rim would be released end of Jan or early Feb too.
So we would have 26mm internal hooked rim at 35/40/50/58/65/78mm depths options.

Hey Peter
Thanks for the update and I hope you are well
What is the T1100 weight estimated to be for the 78mm Rim.
And I'm not sure if its technically possible but will there be 16/18H version planned for this hub type?

The tires are still the stock Schwalbe G-One Bites in 45c that came on the bike. I was running 35psi in the stock wheels for pavement rides and 30psi offroad. These wheels are definitely firmer at the same pressure so I need to play around with lower pressures. The tires are ok offroad but I'd like to switch to something like a 42 pathfinder or 45 g-one rs for a little more speed on the road. In my area I end up covering a lot of road between gravel/dirt sections and I'll likely be using this as my road bike this winter.
Can you tell me how wide the Schwalbe tires actually are on the rim? Thanks and Merry Christmas 😊
-
I just ordered a set of 50/36 gravel wheels from Peter, and anyone who wants to take advantage of the cool discount should hurry 😉
- CS-D50CU-36 T800 rim matte finish without access holes
- R280 36T hub with TPI steel bearings
- 24/24 Sapim CX-Ray spokes
- should weigh under 1400g 👍
….and I'm really looking forward to them 😁
The wheels will replace my Zipp XPLRs, which are unfortunately a little too wide for my light carbon LCR018 frame 😬
-
Hey Peter
Thanks for the update and I hope you are well
What is the T1100 weight estimated to be for the 78mm Rim.
And I'm not sure if its technically possible but will there be 16/18H version planned for this hub type?
He told me 1365 g for the ultralight hub with 20h 5 mm carbon spokes. I will order one when its available to replace my current 65 mm XMC wheels.
-
He told me 1365 g for the ultralight hub with 20h 5 mm carbon spokes. I will order one when its available to replace my current 65 mm XMC wheels.
Thanks man
So the rim is about 495/500g which I thought it would be in this ball park.
This is an excellent weight for this depth compared to rim currently on the market.
75mm I have see at 540g and 80mm 560g
-
I would like to present another wheeset from Peter. This is my second, previously I had 35 mm depth.
For that time I decided to go with:
- 16/18H
- D40CU-33 26mm internal
- 3.2mm super light carbon spokes
- XDR driver
- black hub
Maybe this is not the lightest wheelset ever, however, for 40 mm depth with 26 mm internal, the total weight is 1055 g so...ultralight. Those looking great, on real even better! The rims are very wide, I love that! I put TPU tube, tape on each wheel and Continental Tire Archetype so 30 mm TL tire. For now the whole set is 1678 g. Then you can add 401 g (85+72+232+6+6) and we have ~2080 with full wheels with cassette! 8) Easily you can go down using lighter tires ~50 g each.
I didn't ride on it yet, but as always I can fully recommend the purchase. Great communication, great knowledge, good advices and quick shipment! I'm more than happy!
-
A week ago I ordered a gravel wheelset from Peter at https://www.xmcarbonspeed.com and today he sent me photos of the finished wheels, which will be shipped tomorrow 👌
50mm deep / 36mm wide / 28mm internal / 36T in-house hub / Sapim CX Ray spokes / no access holes
Yes, the wheels aren't the lightest, but I don't care because I want something permanently stable, and something in this class costs about twice as much in Germany 🤷🏻♂️
I'm really excited and can't wait to try them out 😊
-
Curious if anyone else has popped the ends of their wheels to check for grease. All 4 are dry as a bone. I put a little grease in there but curious if anyone else had the same thing happen?

Oh man, this sounds amazing. Either a 65/78 or 78/78 wheelset for my new aero bike. Perfect! Can't wait for these to be released.

I'm excited for these new hubs as well. Will the ratchet ring be titanium? The aluminium ratchet on Tactic hubs is scary, and I'd have thought it could wear even faster if the freehub is titanium. If both are titanium, these hubs could be a giant killer.
-
Extralite also use alu ratchet rings, witha pretty decent track record. Personally, I wouldn't want to ride that either, but they won't necessarily fall apart like they're made of cheese.

Hi.
I would.like to know if someone feel any speed wooble with Xiamen carbon speed with depth bigger than 50mm when descending straight with crosswind or sidewind and speed more than 50-60kmh. Lets said how they feel with such conditions.

Hi.

It depends. I can describe my own experience.
I have D65CU-33 T1100 rims, 20/20H, with 5 mm carbon spokes. With no wind, everything is fine and the wheels are super fast, but you still have to be careful when larger cars pass you at high speed.
In windy conditions, you still need to make small corrections. In strong winds, it is not possible to ride with these wheels.
The problem is that the front wheel is simply too light and has too much surface area exposed to the wind. This issue with ultra-light, high-profile wheels has also been discussed on The Nero Show, if you know it.
My solution is to keep enough weight on the front wheel, have strong arms, and stay focused while riding. After a few months, you get used to making constant steering corrections, and eventually you don’t even notice it anymore.
My weight is 80 kg.

The idea that 100g off a set of wheels is significant enough to affect their handling seems implausible. More likely, the shape of these rims or the geometry of your bike is the reason why riding deep wheels in crosswinds is hard for you.
Crosswind instability arises from a sudden pressure difference between the wheel's two sides as the wheel enters a stall. Once in motion, a heavier wheel would have more torque-induced precision, not less. Looking at the wheel in isolation, a wobble induced by a stall would be worse with a heavier wheel and better with a lighter one. Meanwhile, if the effect is one of system inertia, the mass of the wheel is inconsequential in relation to the mass of the system.
I would love to understand where the Nero guys, Joe, or whoever started talking about light wheels being less crosswind-stable just because they were lighter got the idea from. It doesn't make sense to me that it would be significant.
-
The nero show guys love to larp with engineering oriented talking points, but it's always plainly obvious they didn't think too deeply on any of it when they do.
-
Though I deduced the issue with the light front wheel myself, because in show #154 they tested the Factor One with the new lightweight Black Inc carbon-spoke wheelset, and the behavior Jesse described was exactly the same as with my XMCS wheels.
But here’s the funny thing: I have a Winow WR054 bike with that crazy 6.5 cm wide fork, very similar to the Factor One. Maybe the wide fork is also a cause of this unstable behavior.

Hi.
I would.like to know if someone feel any speed wooble with Xiamen carbon speed with depth bigger than 50mm when descending straight with crosswind or sidewind and speed more than 50-60kmh. Lets said how they feel with such conditions.
I have a pair of 50mm 28iw rims on an all road bike. Crosswinds and speedwobbles are constant. It may be the rims or it may be the bike but I have not had the chance to play around with either. my 40mm 26iw rims on my road bike feel much more stable. both wheels are XMCS.

Have you tried to install 40mm and 26iw wheelset in you all road bike to check if the speed wobbles comes from the bike or wheels?
-
For now I have/had a set of 50 mm Elite Edges (on two different frames) and before 60 mm SLRs (on the third frame). While I felt crosswinds with 60 mm wheels which are noticeably heavier, my 50 mm are super stable and I have no wobbles. I ordered a set of 58mm deep 26 IW wheels and live in a windy area, let's see how Peter's wheels will perform at this depths.

Dear All,
Firtst of all, a happy and, above all, healthy new Year.
I got my wheels last week and installed TPU tubes fom Barbieri NXT Road 65.
I have not installed the wheels in my bike (waitung for the frame)
Today I heard a loud bang and the tire was flat.After I removed the inner tube, I saw that there was a hole in one of the rim's recesses (see pictures)
I installed the inner tube without rim tape, as I thought that was only needed for tubeless setups.
Do you know this problem?
-
You always need rim tape if there are spoke holes in the rim bed ;D
-
@PeterXu
Do you laminate your rims in-house?
Do you drill drain holes as standart and what are your thoughts about drain holes?
What's recommended tire size for your 26mm inner width rims?
Lots of questions ;-)
I've built wheels with timetec, carbonal and carbonbeam rims so far.
Might try yours next.
Thanks for answering.
Oh and if possible, implement prices in EUR on your web site ;-)

Yes, our rims are made in our own factory.
Our rims are drilled with drain holes/ pressure relief holes as standard.
Minimum tire size on our 26mm internal hooked rim is 28C, 30/32C are perfect fitting.

100% agree. I also find that running a deeper rear than front helps, whether its from different stall points or simply that the aero center of pressure in a crosswind is moved rearward away from the steering axis.

Thank you for your answer @PeterXu
As there are manufacturers who offer drain holes as standart and others who offer no drain holes as default, I would be very interested in your opinion about drain holes in general, their size and their exact location in regards to the rim bed. Peter, are you willing to share?
-
At this point the need for drain hole (well vent hole really) has been well documented and the only reason not to do it is to save money by cutting a manufacturing step i think
-
@Ludo I disagree. If it was just for venting, you wouldn'd need drain holes in tubular rims and real tubless rims, the ones without nipple access holes. IMHO drain holes have the main function to drain any moisture out of the rim. A fellow cyclist in a local group here just asked around how to drill drain holes in a wheel set without, as he gets water inside his rims when gravel riding in the wet. I told him to take a sharp drill and just do it, as I've done it before.
Now I just got a set of chinese carbon rims where the manufacurer doesn't drill drain holes as standart but did it on my request, and I think they shoud be closer to the rim bed for beeing more drain effective useing the centrifugal force without letting water left in the rim.
If there's a full discussion on this topic somewhere I'm happy to konw where to read.

Funny Story Time
A company sent me out a set of wheels to review. Upon delivery of the wheels not only are they HOOKLESS, a detail they failed to mention anywhere on their website, but the rims have no drain holes. Double whammy.
I immediately and respectfully emailed the company asking about their thought process. Telling them to update their website to include hookless in the description but also the decision not to use drain holes. I offered a couple of valid reasons why almost all wheel brands include drainage IE pressure relief and water ingress drainage.
Here was their response:
"This comes down to a design choice rather than a flaw. Some brands incorporate drainage holes, others intentionally do not. In fact, in the mountain biking space many riders prefer rims without them. While drainage holes can serve a purpose, their absence isn’t considered a defect and ultimately falls into a preference-based design decision."
To be fair, the wheels are ultra budget entry-level. But I took their response as some sort of corporate deflection tactic.
-
I think the role of drain holes in rims for venting is sort of overblown because the visual of exploding rims evokes such strong reactions. I don't think they are truly needed as a requirement, but I like to see them because I prefer that my rims can dry out if water gets in there.
I don't think any of my MTB rims have drain holes.
100% agree. I also find that running a deeper rear than front helps, whether its from different stall points or simply that the aero center of pressure in a crosswind is moved rearward away from the steering axis.
The rear doesn't need to be deeper, just more aero at shallow yaws to get this effect. See the new Rovals for an example of this.
-
I'm not sure I understand the holes for venting at all. It could only really be a problem if you're running tubeless, but then you'd have sealant that would literally seal the hole.
-
The venting through holes on the rim - normally 2 in total, one one each side, is seen to be necessary when you run a tubless set-up in a rim with nipple access holes ans theirfore tubless tape, and the tape let's pressured air from the tire I to the profile (chamber) of the rim.
-
I ordered two wheelsets from Peter. One new 78 mm road wheelset with the ultralight hubs and one gravel wheelset.

My elitewheels 5 spoke wheelset has no rim holes but its got 2 drain holes, air can leak to the rim cavity because any bike rim will always have a valve hole.

Do we have any profile drawing of the new 78mm rim yet? Haven't seen it at least, but maybe I missed it?

You can still leak though the valve seat on tubeless set up
-

Most of the rim explosion/delamination seem to happen when applying quick pressure to seat the tire in, before you put sealant. I delaminated a rim exactly like that, due to leak at valve stem seat.

Looks great! You are gonna be flying bro.
What are your thoughts about the new wheel decal design? Particularly the size of the decals in relation to the rim depth. To my unprofessional eye, the decals should be larger to fill out the space more. Similar to Zipp's 808.
I think for the moment Peter might be using the same size decals regardless of rim depth. I messaged him about this earlier, and waiting to hear back.
-
Yeah they maybe could scale a little bit with the rim depth but as the letters are cut, I think the overall look matches the rim.

I finally have the full suite of XMCS components setup on my Bossi Strada SS. Pretty much have this bike setup now identical in terms of bike fit to my actual race bikes. But I just cannot overstate how smooth of a riding experience you can have with a titanium frame, titanium spoked wheels, and 30/32c tires. Placebo or not...I don't care.

What is the the tire clearance n your frame ? In my Avenger Shuttle SL I have 32 mm tire. I have no issues with installation of those 34 mm external XMCS wheels. I have still some space. Please not that the rear triangle has different dimensions than the tire clearance. There is much more space there! I also was wondering about that, but I contacted with the expert so Peter directly, and he confirmed.

I am getting a pair of XMCS wheels and am wondering about T1100 rim usage on gravel. A few times in this thread it is mentioned that T1100 rims are not very suitable for gravel like T800 are. Why is that?
Is it the fear of rock strikes to the side/wall of the rim. Or is it the fear of hitting a pothole or washboard too hard and cracking the rim? Do T1100 rims handle stress worse or do they handle strikes worse?
-
They replace some material with a smaller amount of a stronger material. Now carbon fibre is an anisotropic material, meaning it has different mechanical properties depending on orientation. So while the wheel still behaves similarly during normal riding, it's less durable against loads it wasn't designed for, like impacts, because now the tensile properties of the fibre make less of a difference and it's more down to the properties of the resin and volume of material.
-
Yes, thank you. But what kind of imapcts/loads are we talking about? I see two kinds of impacts:
-Direct impacts to the rim: rock strikes to the side, snakebites, tire deflates and you strike the rim directly against the surface.
-Extra force/load: you drive over washboard and rattles you and the rim like hell, you hit a pothole generating extra force on the rim, you drive over a curb, bunnyhop. Basicaly generating extra load but not directly touching the rim. I am not talking some extreme full force hitting a giant pothole, but rather normal controled every day impact you know :)
I was at a UCI gravel race in April and people were going 1000 watts over forest paths with big roots on their zipp xplr wheels for example. I imagine that is too much even for xmcs gravel 32mm IW T1100 rims? I ordered 40mm deep 26IW rims.
At least I want to know how fearful should I be about potholes and curbs and washboard. I hope not too much :)
-
The biggest difference will be in impacts on the side of the rim.
Now the rest is speculation and you'd have to ask XMCS for a true answer, but the hooks have a non-negotiable amount of volume that needs to be filled. I doubt the material used there changes between layups. Density of Toray fibre is almost identical for all but two grades, so you don't gain anything from changing the material there. The cheapest structurally sufficient material should be fine for every layup level. For vetical loads, the side walls could be built to the same strength across all layups, but I don't know if they are. It's entirely possible the lighter layups get rid of so much material that they are still weaker while using a stronger material.
-
I also would be interested which road wheels are also suitable for gravel use. I am planing to use a GP5000 35mm, are there any rims which create a flush areo shape optimized for this tire size?

As permanent resident of the bro science corner, i'd say a rim that's 38-40mm wide should be optimal (rule of 105, aka bro aero). I have a Conti GP5000 32C on a 34mm wide rim, it measures 34.4mm from memory. Therefore, a 35C Conti GP5000 on a, say, 39mm rim, should measure anywhere between 35 and, idk, 40mm. As such, on paper, assuming your rim is hooked (do not get a hookless rim for that), you should have a rim that's a bit wider than the tyre, following the rule of 105. At the very least, you wont have a mushroom (tyre much wider than rim).
The Silca dude said on a recent YT video that you lose 6-7W @45kmh using a 30mm wide rim with a 35C tyre, vs a 32C. Mushroom effect is real, rule of 105 is the best rule of thumb we have for a good tyre - rim interface.
Last, i think people say that the wider the rim, the deeper it should be, for the wind to play nice. So i'm eyeing 50-60mm rims myself, i wouldnt go shallower than 45.
#Bro science.

I'm not sure if XMCS has that in offer, I haven't seen any on their site, but there is a rim 30int/36ext available that should be perfect for this tire.

Well, the name is self explanatory. It is stated as gravel/road wheelset. I bought T1100 rims with steel spokes and it survived pretty bad potholes when I bottomed out at high speeds with ~34 measured width tyres. I won't recommend combining ultralight carbon spokes with ultralight rim, though.
-
So for mixed use steel spokes are the way to go right?
@Serge_K: I think you are pretty spot on. So for the 32mm tires do you think the 26 iw rims create a good transition between rim and tire?
For the 30int/36ext it would be nice if Peter could test the real world measurements of a 35mm tires. I think there will be more demand for 35 and 40mm road tires in the future, like the new GP 5000.

I think I wrote it several pages ago... My Pirelli RS 30/32 mm tyres on 26/33 rim expands to 33,6/34 mm. The transition is very smooth in front and at the rear it doesnt matter.
-
If you want the smoothest transition ever mount the new Pirelli SL R tyre. No more gap between rim and tyre just one unit

Hello everybody. I'm interested is buying an XMCS wheelset around 50-60mm (specifically the 50/58) deep and 34mm ext width and was looking for some advice on spoke width and spoke count. What would be the performance differences between the 3.2, 3.8 and 5.0mm spokes and 18 vs 20 spokes? I was looking at the 50/58 depth wheelset. I'm a pretty lightweight rider but my focus is pretty all-round. Which one would perform the best?
-
We have arranged 50/50, 58/58, 65/65mm 26mm IW T1100 version built with R506 hubs 20/20H and carbon spokes combo wheels UCI approved, I believe they will be listed on the UCI official website soon. And the 58/58mm combo wheels are wind tunnel tested with very good result, compared with some other brands wheels.

We have arranged 50/50, 58/58, 65/65mm 26mm IW T1100 version built with R506 hubs 20/20H and carbon spokes combo wheels UCI approved, I believe they will be listed on the UCI official website soon. And the 58/58mm combo wheels are wind tunnel tested with very good result, compared with some other brands wheels.
Great News! Amazing! I keep my finger crossed! The bike looks really amazing!
-
Do you expect the new layup with HS606 hubs to also pass UCI approval? Also is it possible to get the new big XMCS decals in laser-silver colour on the new layup wheels?
Our wheels can easily pass the UCI standard (40J), UCI approved stuff means nothing on quality point, it is only meaningful for selling and UCI race event. We will arrange more combo wheels for UCI approved though, including HS606 ultralite hubs too. And yes all our decals can be applied onto all our rims.

Is a wheel with HS606 hub less (lateral) stiff than the exact same wheel with R506?

I upgraded my front hub on one of peters T800 D50-33 wheelsets to a dynamo hub for ultras.
Complete weight of the wheel set is now 1627 g for 50 mm deep rims including dynamo, can’t complain about that :D
Otherwise, my T1100 D50-33 20H carbon spoke wheelset has now seen 4000 km without any issues, still stiff and true.

65/58mm, 3,2mm spokes ultra hubs, but with steel bearings
Couldn't bother to change the GP5000 orientation..

T110 carbon layout? Are they stiff enough for you (for which body weight)?
-
65/58mm, 3,2mm spokes ultra hubs, but with steel bearings

Custom IW 26mm wheels?
From the catalog, I see that the 58/65mm rims should be fitted with 3.8mm carbon spokes.
That would be a very interesting combination for me too....may I ask how much you paid for them?
Thanks

To those with who have R280 hubs, do you know if there is any 3rd party compatible freehubs? I need to change from HG to XDR.

@PeterXu please adapt the logos to each rim depth. Here, in my opinion of course, it should start from the inner side of the rim (no gap) and be larger
eg. an example of "same logo size for every rim depth is wrong" is the following

Hey everyone,
has anyone ordered nowadays wheelsets delivered to the EU? How long did it take until the delivery? I'm thinking of getting CS-RDW-H-50-30 with XDR freehub (with grey decals if that matters) for an event in the end of july.
Thank you!

Hi,
I bought a set of these wheels(Link #1)and need a replacement freehub body. I read somewhere that DT Swiss 180/240/350 might be compatible as long as its the ratchet version (with exception for EXP version). Can anyone confirm that they work for my wheelset?
Will the freehub body in link #2work? If not, can anyone link a specific XDR freehub body that works?
Thanks in advance

i bought that particular XDR freehub, but it does not seem to be the perfect fit. maybe I'm doing something wrong.
I can't torque the axle to its intended NM, without the wheelset locking up. Pedaling forward works fine, but pedaling backwards does not work.
Only once I loosen the axle, does pedaling backwards work again. But that doesn't feel secure.
maybe someone experienced can help out? much appreciated!
-
Did you mess up the ratchets inside the free hub?

Sounds like something isnt correctly installed. This is common when freehub bodys seizes and/or ratchets are engaged. This happened several times with my previous set of wheels when my ratchets wasnt lived or were too dirty.

XMCS update for my SSE; 58/65 mm, 26 mm inner width, with 20 spokes. Love it!

Took a little more effort to get these speced and ordered. I think the Campy Hub body through an added challenge.
This will be going on a Neo-Retro steal frame.

I did purchase and receive few weeks ago some 50 deep with 26IW with CX ray spokes with R248 hub in UD paintless.
They weight 1250g and feel very light on the bike.
Unfortunately, since I mounted this new wheels I'm experiencing a problem with my front brake (Ultegra 8170Di2 on a Lightcarbon LCR018 frame).
My front brake is sometime making a loud metallic noise while braking (not necessary on strong braking). This never happen before mounting these new wheels.
What is also strange is that it's sporadic : on some ride, I don't have noise for 2 first hours and then it start.
I did few trials to identify the origine of this noise and it seems to be related with the front wheel.
When I put back my old wheel (reinstalling the same disk) I have no problem.
I did try to install a new disk and new pads without solving the issue.
I did also try to use new resin pad (instead of metallic pad) + other disc without resolving the issue.
The disk is tightened with a torquewrench at the right torque (40Nm).
Do any of you experience this issue ?
I don’t really understand what could cause this : do you have an idea ?
I will also continue to try making other test (maybe test them on my other bike).
I'm not feeling vibration while I'm braking but the noise is realy not nice and I'm not confident going downhill with this phenomenon.

Hi, a quick question for those of you who ordered XCMS wheels without spoke holes. Any issues? Do you regret it? i I have ordered my 3rd set of wheels from Peter, a gravel set, and may change to no spoke holes. I have run tubeless for years so not havng to use tape would be a bonus. Cheers, Bob

Did you realign the caliper? When I swap wheelsets I have to do this because of slight differences in the hub tolerances that move the discs slightly.

Hi, I'm interested in ordering some XMCS wheels but wondering what's the best way to order it from? Is it the website or mailing them directly? Website seems like the obvious choice but seeing a lot of you in this thread looks like go the email route. Hence why I'm wondering

Anyone else have this wobble "issue" with their wheel?
In the bike
https://youtube.com/shorts/KCCwd8qeQxw?si=K4LyOnpoAfr2BAP1
same wheel in my truing stand.
https://youtu.be/_0UgBW_d1-s?si=3sitD-ZA-IfULPnU
These are new wheels, has about 60 miles on them. After the first ride I checked the wheels and found this wobble, it's on the front wheel only and the rear appears to be fine. What's odd is the wheel is still true, and the spokes tension is still even and consistent, only the inner part of the wheel has this wobble.
I spoke to Peter and he said it's normal. He mentioned because of the ultralight carbon layup, the spokes can pull and deform the carbon to make this wobble.
Wheel model is
D58CU-33 26mm IW T1100 with HS606 hubs and 3.2mm carbon spokes. Weight is 1165g.
System weight is about 75kg.
You guys have any thoughts on this and does anyone else have this issue on their wheel??
Also, why doesn't the rear wheel have this issue as well?
Peter told me to post in the forum as others have mentioned this? where?

I'm trying to determine if this will rip apart in the long run. How long have you had your wheels?
-
I got them in September of last year. I have a set of the ultra light rims with 16 and 18 carbon spokes. I’ve ridden them on rough trails, bombed then down mountains, and packed them tight in bike boxes to fly. No issues. Still true. The layup is thin. You can squish it on the sides with your hand. However, in the vertical plane, they are incredibly stiff and sturdy. The tension on the spokes is very tight, and pulling the layup at an angle. I’m not surprised it deforms the inside of the rim a bit. I’m not very concerned about anything catastrophic, and I’d guess Peter would take care of me if I had a problem due to an engineering or manufacturing issue
-
Does someone have a spoke tension chart for the wheels?
Yesterday i caught a stick with my front wheel, snapped a spoke and now its a bit defomred with an 8. LBS would like to know the tension charts before he tries to fix them. And its a bit urgent since i need them for Saturday
D50CU-33 T1100 rims 20/20H UD paintless no logos
Carbon Speed in-house hubs black color 54T rachets TPI ceramic bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
5.0mm carbon spokes
Already contacted Peter simultaneously.
Would appreciate your help :)

I had the same but on farsports wheels. The noise is getting worse the more kms you ride.
Together with my LBS we identified the wheel caps and hubs slightly out of spec causing this. Farsports replaced the wheel caps and it solved the matter.

Thanks to your advice, I did check a bit more the clearance between the thrue axle and the end cap.
I took the same thrue axle to compare the clearance between : the XMCS front wheel, the XMCS rear wheel & a winspace front wheel.
There is definitly much more clearance in the XMCS front wheel than on the XMCS rear wheel orwinspace front wheel.
I will contact Peter and I'll let you know how

I did check the wheel cap inner diameter and it seems similar to the rear wheel.
The additionnal clearance is due to the front wheel "tube" being oversized vs the rear wheel one (see pictures).

Good morning. I removed the freehub body from my Carbon Speed wheels to apply some fresh grease, and I noticed that—after 800 km—the 54-tooth ratchets are starting to show signs of wear (nothing too serious, though). I wanted to ask if these ratchets are standard DT Swiss compatible and if I can buy the ZTTO brand ones on AliExpress. Is it better to go with steel or titanium? Thanks.
-
they're std Dtswiss but new model with inner groove and not the old model without.
I swap 3 different ratchet from different wheelset/source without any problem.
The spring are not all equal, some springs are not compatible with grooved spacer (it's a matter f 0,1mmm)
There are 4 different set of springs:
conical springs (old model)
cilindrical springs (with round wire)
cilindrical springs (with flat wire)
cilindrical springs (with flat wire "double loop")
+additional trick: spring on one side, teflon ring on the other one
Is the difference from 54 to 60 noticeable? Yes.
The crisper the sound (in garage) the higher the headace in long alpine descent...
if you match correctly you can manage the balance between drag/sound...

Thanks for the reply. I didn't think it was so complicated; I thought it was standard. Anyway, these ones from Ztto look the same as mine.

They cost a little over 20 euros.

Sign of wear after 800km seems really really early it should be basically new ?
Btw the 54t original from xmcs was too loud for my liking. I cleaned it and used Dumonde freehub x grease and I’d say it’s better. Definitely not silent but not annoying anymore, perfect !

Any photos to see the wear?

Anyone else running the 26int/33ext rims with 30mm Pirelli P Zero SL-R TLRs seeing sidewall wear when cornering hard?
It looks like the tread just isn’t quite wide enough for this rim/tire combo. I also saw on Bicycle Rolling Resistance that they measured the 28mm version as actually having a wider tread than the 30mm, which seems a bit odd and makes me wonder if that’s part of what’s going on here.
I’ve attached a few photos of my tires. I’ve only done two crits on them, both with mostly left-hand corners, and you can already see pretty clear wear extending down the left side. I’m curious whether this is something Pirelli has seen before and whether they’re likely to address it.
Bit of a shame, because apart from that they’ve been great — fastest tires I’ve used, and no punctures so far after 1,600 km.

Yes, me and my sidewalls are totally fine (but my cornering is surely not as hard as your). The SL-R are not made to last very long so I assume after 2.000 km they will be dead.

Thanks for the reply. They aren't exactly worn out; the chrome surface coating on the ratchet mechanism has simply flaked off—that’s all. It’s only on the outer edge and doesn't affect all 54 teeth; it’s a minor issue. You can see the color difference between the grey metal and the chrome plating. I assume it's normal wear; the teeth themselves aren't chewed up. I took them apart because they were making a lot of noise, applied more Teflon-based grease, and the situation improved.

No, I'm afraid not; some of the chrome plating came off the ratchets—specifically on the outer edge, and not on all of them. A few tiny flakes ended up on the paper towel while I was removing the old grease.

I'm seriously looking into ditching my Enve 45 wheelset on my sworks SL7. I'm tired of hookless and tubeless tape. This has led me with two option. Farsport 50/58 24mmIW 30mm external width or the carbon speed 50/58 26iw/33 external witdth. Does anyone have any personal experience with these wheel set on a tarmac sl7? I shouldn't have any fitment issues?
