Sorry, last topic I made seems doesn't work fine. So this is new one.
Attachments are our newest carbon crankset which would be released after Chinese New Year holiday. 165mm size is under testing, 325+/-5g/ set including 29mm DUB 7075 aluminum spindle, 24mm titanium spindle would be availlable as well.

What is the interface to the spider?
If it’s 3 bolt, NICE! I can use my Magene PM. I passed on some frames because of BB86 and lack of carbon cranks with 24mm spindles that had 3 bolt interfaces. Titanium spindle makes that build much more do-able. Still might be interested in the DUB now that I have a T47 frame coming

Easton style. There might be patent problem on 3 bolts design that is why we don't do bolts version.

Do you have any price for the 24mm titanium version?
-

No yet. 24mm titanium version won't be available until March or early April.
-
What's the alu price? Q-factor? any stiffness test comparisons against the competition?
-
Interesting!
Is the spindle swappable for different lengths? Is it compatible with the Easton spindles?
-
the spindle-crank interface looks identical to cybrei, the arms are different, so no and yes.
Like the cranks arms actually, there were complaints about clearance issues with the straight arms like elilee and cybrei

Looks great, would be interested in a 24mm titanium version.

Ah yes, I realized looking at it that the preload collar threads are on the spindle vs. on the crank. I sure hope they are swappable though, would be nice to be able to get different lengths for gravel setups etc.
-
I got some pictures from the preproduction models. Weight should remain the same for production.

Looks good, but too bad they won't do 3-bolt interface though... There are already a lot cranks that look the same as these, but none 24mm and 3 bolt
-
@PeterXu do the factory and designers making this have experience making big brand or Chinese brand thermoplastic cranks?
SRAM had early problems with delaminating inserts and a few cracks. Easton had a lot of issues early on, and still some now. Various cheap Chinese ones have had the same. Quality Chinese ones from Incolor and Elilee both had extensive issues initially.
I.E. If the factory and designers have experience, we might expect the launch product to work fine. If not ... I think it may be a mess.
-
considering the crank-to-arm interfaces are a 1-to-1 Cybrei copy (probably from the same machine shop), I expect there's probably some other Cybrei sauce in there too

Whats the suggested retail price for this Peter?
Im finding multiple brands are basically doing the same style/design of crank
Lexon
CarbonBike Kit
Sprill/pass quest
Cybrei
Elile
Riro
Leese

Same here, I want 24 axle so badly, but I don't want to get rid of my good old p2Max 3-bolt spider PM...

The DUB 29mm aluminum spindle version could be pre-ordered now, the lead time would be 30-45 days.

Watching with interest. Need the 24mm version.

230 USD/ set for DUB 29mm aluminum version crankset only
We offer spider, different versions chainrings as well: https://photos.app.goo.gl/XwGd4ANeadbm8yrX8

Im guessing no 8 bolt version either?
-
any plans to make other crank lengths? Looking for 155 or 160.

Yes, next size would be 170mm, then 160mm or 155mm
-
I'm super excited for the 24 titanium version. Will be curious to see what spider power meters are compatible.
Currently all my Shimano built bikes run either 29mm DUB/Quarq spindles or Magene PES Base power meters. The Magene probably is most ideal since it's 24mm, but is a bit heavy if you're a weight weenie. And spending $850 on the Cybrei setup is a tall request.
-
it's already confirmed to be easton mount standard...
-
I'm waiting for 24mm titanium 172.5mm ;D

Nice, just patiently waiting for 24mm 165mm version then
-
Looks good nice plain and simple :-)
Ok now wait for the new Quick Pro ER:One some XM Wheels Ultegea and this crank and I'm ready to go!
-
So this will work with the Magene P505 power meter, or am I being daft? If so, that'd be great. As Pat said, the P505 is a porker at 800g+. (170mm & 52/36)
I need to drop some weight from the Magene crank or go to pedal based PM.

No, Magene uses its own proprietary interface for the P505 Base cranks, and does not make an Easton version for the P505 spider. Both XCadey and Sigeyi make power meters to suit the Easton crank interface.
-
What makes you think it would be p505 compatible?
-
What makes you think it would be p505 compatible?
I'm not familiar with the "easton mounting standard". The Magene P505 PM spider is round and has four mounting bolts, not unlike those pictured in this thread (which are apparently compatible). raisinberry777 set me straight. I'm just not that into my p505. I thought having a PM would be the final frontier, but the p505 added 100g+ to my bike, and the data isn't *that* useful.
-
This is still more expensive for me than the Lexon/Ryet branded one on Ali.
What advantages does this offer? No 24mm yet?
-
with the lexon redesign to make it cheaper to produce, this is lighter
-
Looking for a crank + PM + chainrings for a new build. Would love it to be reasonably light, 165, 167.5 or 170mm cranklenght.
Love ordering via Peter, since I have nothing but good experience with him.
However, I have a few questions:
A lot of ppl seem to wait for:
What is the difference between 24 en 29mm? Why would you rather have 24mm?
For the titanium I guess its stronger or lighter (or both) than alu?
Furthermore, what powermeter (spider) and chainrings would you go for? I love a closed ring and riding 52/36.
-
The main reason to wait for 24mm is for people with a BB86 frame, since a 29mm DUB crank (made of aluminium) requires the use of smaller bearings. 24mm needs steel or titanium - aluminium has a risk of shearing at those smaller diameters. Weight is roughly the same or slightly in favour of the aluminium cranks normally. If you have any other type of frame you might as well use the 29mm version.
Chinese PM options are XCadey or Sigeyi, they use the Easton interface.
Best Chinese chainring options are Stone or Pass Quest. Lexon is another option.

Thanks!
Since I'm going for a BSA BB frame, I can just as wel go for the 29mm spindle :)
-
For me, the biggest reason to choose 24mm is that with a BSA or BB86 frame, the bearings are very small for DUB and 30mm axles. So You have better durability (of course there is anecdotal evidence suggesting otherwise...) if you stick with a 24mm Shimano standard axle.
-
Bsa bearing are positioned outboard the bb shell. The only thing limiting the bearing size is the bb itself

Probably repeating what everyone has said, but a 24mm spindle—especially in a BSA bottom bracket—means larger bearings, which naturally last longer.
I have a DUB Cybrei on my SL8, and since I have a press, swapping it is no big deal. Longevity isn't a major concern for me, but I do use steel bearings (SKF/NTN). I previously had a THM Clavicula with their ceramic bottom bracket, and it was terrible—bearings didn’t last, and as a heavier rider, it was noisy as hell when climbing out of the saddle. That was super annoying since I need everything to be completely silent. I ended up selling it and went back to my Dura-Ace crank before getting the Cybrei.
I’m currently running 54/38 MetAero Cybrei rings with an 11-34 cassette, paired with an X-Cadey power meter, which works fine. I’ll be testing this setup in Gran Canaria next week ahead of Mallorca 312 in April. We’ll see if my legs blow up—if they do, I might switch to 52/36 rings.
-
In case someone wants to have good solution for BSA:
SRAM Red E1 arms (308g, DUB)
Sigeyi AXO (110g)
Shimano chainrings (147g)
Total 580g
-
Has anybody tried one yet?

The bearings typically used for 30mm/29mm/Dub (6806 or 6806-29) and 25mm/24mm (6805 or MR2537) have the same size balls. BB86 is the only standard where you should want a 24mm axle.
-
There's a mix regarding DUB and BSA bottom brackets. Despite not being limited by size, SRAM still use smaller bearings on BSA bottom brackets. Some other manufacturers like Wheels Mfg use 6806 bearings.
See here:
https://weightweenies.starbike.com/forum/viewtopic.php?t=165166
However, it's also worth considering that loads of major bike brands use either BSA or BB86 frames with SRAM builds and there are seemingly no reports of widespread issues.
-
I just received the LEESE LSE-C01 carbon crank from Aliexpress which took nearly a week to arrive in Asia. The format is in EASTON DUB as I have the TIME Alpe d'Huez in DUB, making the swap a straight forward affair should I replace the current crankset.
The crankarms are detachable from the DUB axle which made installing of spider or powermeter a breeze. Indeed I have a XCADEY Gen 2-S powermeter spider lying around since the previous LEXON Carbon crank could not install this spider properly. All I took was less than 5 minutes to assemble the powermeter together with the crankset and it was all set to be mounted on the bike. Of course, I do not have a torque wrench to go 40nm but a good yank of the allen key till there is no play is probably going to keep things together.
Total weight is 500 grams flat = crankarms + axle + XCADEY Spider; compare that to a Shimano Ultegra R8100 crankset which weighs 700 grams without chainring and we get a decent 200 grams shaved off.
I have done a short introduction video here - youtu.be/SdwSQCgpMFM in youtube.

SRAM uses that smaller bearing in the PF30 as well. I have not looked at a t47, but no reason to believe it would be an exception. I believe they use the same bearing across the range. It's a custom bearing you can't buy, so it's very much a one-off.

Bit less for the weight savings - Ultegra R8100 is 547g in 165mm without rings, see here:
https://handsonbike.blogspot.com/2023/09/12-speed-crankset-comparison-dura-ace.html?m=1
In any case, better off starting a new topic as this is for the XMCarbonSpeed cranks, not the Leese ones.
-
Yes I concur with the above poster my r8100 with 52/36 rings in 165mm is 709grams.
I'm looking forward to the 24mm version to see if it's worth getting over the dub axle.

I've just got a new grouspset and weighed every component

I was just confirming the weight of Ultegra cranksets as surely the point of a Carbon crank is it is lighter?

wow thanks for the information its exactly what we wanted. none of us knew that the aluminum crank with a steel spindle is heavier than the ultralight carbon crank and we couldn't look it up. Thanks for the info!

eneral question on this and other Carbon cranksets. I am around 100kg and wondering how carbon cranks hold up with heavier riders. Any experience or ideas?

I'd hardly consider shimano the gold standard of cranks

Should be fine imo, although if you have cash done waste it on THM tough ;D had one at 90kgs and was a bag on sh1t any climbing out of saddle noisy as f1ck! and fiddley as f1uck as well to set up. For the 60/70kgs rider!

We don't sell any items without QC, we have been doing the in-house testing for couple of months and had some pros tested these cranksets too, otherwise how could we announce releasing them? Thanks for your concern and questions.
-
@PeterXu when do you expect the 170mm dub crank to be available? Thank you.
-
Dude, relax. Yes, it is helpful to know the weight of the gold standard crankset when considering buying a premium avant garde piece of kit.
I wouldn't worry. 100kg isn't THAT heavy, and i suspect you're not a track sprinter. Don't buy ultra lightweight components, like these cockpits that are pool noodles because they weigh nothing. Ditto, dont get feather weight aluminium cassettes. You'll probably wear out chairings fast if you get chinese ones, but they're cheap.
These carbon cranksets have been around for many, many years, i've had a sram red carbon crankset on my rim brake bike for a million years. As long as there's no manufacturing defect or dumb design (raceworks had a dumb design), you should be fine.

LOL I didn't realize they were a sticker. I guess I could just slap on some 3k carbon wrap I have kicking around.
-
It's not. Its a carbon front plate , bonded to an aluminium backplate. The point is that the carbon plate gives you strength and aluminium gives durability and shifting performance

Sry, was referring to the Cybrei ones.

Peter's are for sure. I was in contact with him a month ago after I bought a frame from him and some wheels. I asked him to message me when they are available. I want to use a 1x with the R01 I bought.

165mm both 29mm DUB aluminum spindle and 24mm titanium spindle options would be available in May, orders accepted for now. And the chainrings too.
Chainrings spec.
Double rings:50-34/52-36/53-39/54-40
Single ring: 46/48/50/52/54/56/58
Next sizes would be 170mm and 155mm cranksets. We are making carbon sprider as well.

Congrats! I really like that the spider is actually shaped CF weave instead of what looks like forged CF from Cybrei (Cenit?). Though I'm a big fan of the 4+5 bolt compatibility on those.
-
Gratulation!
Chainrings looks good. But they’re a bit heavy right? Or am I mistaken. Dur ace is around 13x, as is cybrei?
But that’s probably without the bolts
-

The 178.4g weight is for 50-34T double rings together including the bolts
-
Hm, the bolts are around 5-8g, so it’s 14x for cybrei or dura ace.
So considering DA around 30g penalty for aesthetics, more expensive, unknown shifting performance and durability. Or am I missing something?
What’s the weight of the crankarms 24mm if I may ask? And do you have more photos please?

The rings are $165 USD, which seems pretty fair. Cybrei’s go for £262, and I think Peter said some pros have been testing theirs.
I’ve got the Cybrei metal rings, and they work great, but maybe a bit noisier since it’s carbon plate on aluminium, so you get more sound transfer.
The cranks with 24mm spindles all weigh around 320–330 grams.
I'm getting a set have asked if peter can do me 54-39t as Shimano recommend no more the 16T jump between form chain rings for shifting performance. That's why I like the Cybrei 54-38T set up.
If not I will opt for 53-39t

Sure it’s fair compared to cybrei and carbon ti.But so far there is no objective review that we know of regarding their performance etc.
And the weight is higher than ultegra and probably slightly lower than 105.
(May be wrong about the weights tho, seems like it’s purely aesthetics, not performance/value oriented)

165mm 24mm titanium spindle crankset.
I noticed these cranks also have a “shoulder” where the spindle attaches to them. Is there a reason for that? On my lexon cranks that shoulder causes a significant gap between cranks and spider/chainrings and is also the reason why the chainrings sit very close to the frame, making it difficult to set up the di2 front mech properly.

The spider supplied with the XM crank is recessed to allow it to go round the shoulder.
Have you the correct spider type

Peter, do you have 1x chain rings for an XPLR set up?

For anyone considering chainrings from XM Carbon — I’ve had two sets arrive: a 52/36T and a 53/39T.
I didn’t buy both — XM accidentally sent the 52/36T in error. But to be fair, they responded quickly and sorted it out. The correct 53/39T set arrived today, and the 52/36T was delivered on Monday.
Side by side comparison to the Cybrei rings will post pics when I fit to my DFS Carbon crank with complete weight

carbon decal on a milled aluminium chain ring?
-
carbon decal on a milled aluminium chain ring?
it’s not a decal. It’s an aluminium chainring with a carbon fibre insert, very similar to how Cybrei makes their rings. I’m assuming from the “decal??” comment that you thought it might be a sticker or something purely cosmetic, but it’s not. It’s an actual carbon insert bonded into the chainring, like the ones from XM Carbon Speed.
To be honest, I don’t think it offers a huge performance benefit — maybe a small weight saving compared to a full aluminium ring, but it’s marginal. For example, I’ve got the Cybrei carbon chainring on my bike, and the aluminium version is only slightly heavier. Peter sent me the Miché link — the construction shown there is pretty much the same.

It's not really that similar to Cybrei. Cybrei chainrings are hollow, similar to shimano. It's a carbon plate, a gap in the middle and an alu backplate. This lets them make a stronger cross section with less material. Cybrei will have a better weight to lateral stiffness ratio, and with their specific design, shifting is likely to be better

Side by side similarities
Technically maybe not will see what shifting is like.
And they will look good 😂

My new cranks are on the way. Peter has said they are Easton interface and has sent me a picture of the spider. I can see it has 4 bolt holes for attaching to chain rings though its not immediately clear to this dunce what fitting they will be. I am after a single chain ring, probably 42 and either an oval or aero for a 1x xplr set up. Can anyone more knowedgeable guide me on what i should be lookking to buy? TIA.

you just need a 1x chainring that uses the shimano standard 4x 110BCD mounting pattern. the easton interface is how the spider attaches to the drive side crank arm.
something like this in a 42 or a 44 with a 3mm offset.

choose a chainring that's still shimano 4x 110 bcd but compatible with SRAM flat top chains like the one linked below for example. the pass quest one also supports SRAM flat top.

Thanks, Ibreally appreciate the advice and links.

Another silly question :)
Can i not attach an Easton interface 1x chain ring directly to the crank in place of the spider?
-
Bumping this because i forgot to order the spider from Peter :)
Will this fit? It Easton so why wouldnt it?

an Easton Cinch direct mount chainring should fit directly on the cranks. Not sure if they have a shoulder on the crank arms that might complicate it, but doubt that.
-
I doubt it too so will take the risk-cheers!

Why no 160mm cranks! Sad face. :( I suppose I'll give 155 a go! :D
Can anyone confirm whether or not the single chainrings Peter offers are narrow/wide for a 1 by setup? Or are they prices just for the big ring of a 2 x setup?
I've sent Peter an email for a quote in any case and if the chainring isn't a narrow/wide 1 by specific ring I'll put the order in for a crankset + spider.
Thanks again Sander for doing the research and bringing yet again another product to my attention! :)
EDIT: Peter got back to me with a quote and I'll finalise the order once I decide on a chainring size. I asked him to confirm that the single chainring is in fact narrow/wide for 1 by, but he did not confirm, but he did quote me for a single speed chainring for 1 by so I'm assuming it's all good.
-
Here are some photos.
I think it’s great that there is a washer for the spider lockring.
On the non drive side however the supplied spacers are a bit too smal, I.e. their outer diameter is smaller than the inner diameter of the preload adjuster.
Am I missing something? That way they just slot in and don’t do anything?
There’s one set of bolts too much on the scale.

Now I just need to figure out which PM and chainrings I wanna go with. Any suggestions?

Try the Magene pedal-based PM :D
I wanted to buy Magene pedal PM in the future because walking on Wellgo cleats of Favero Assiomas are shit.

XCadey, as you tested the magene, or Arcrayo (pretty cheap on cyclegear), it would be nice to have the comparison

OK so I just got my crankset today, with carbon spider and 52T 1 by narrow/wide chainring.
I'm running on Dura-Ace, so using a waxed Dura-Ace 12-Speed chain, and the Shimano quick link is "sticking" to the chainring causing the chain to stick on some but not all rotations.
I had to bail out of my ride, but on the stand I can see the quick link is too narrow for the narrow/wide chainring teeth (it doesn't engage completely thus causing the chain to lift off the chainring).
I did some googling and found that Stone narrow/wide chainrings state: You have to replace the 12s shimano original quick link to other brand 12s quick link like KMC YBN SUMC any brand. as the shimano 12s quick link is too narrow.
It's after hours now but I thought I'd raid my parts bin and run a few experiments:
- ZTTO 12-Speed chain quick link, same problem.
- ZTTO 12-Speed chain + ZTTO quick link, same problem.
- SRAM Red E1 chain quick link, no go (stiff links).
- 10-Speed KMC quick link, perfectly smooth (but the link is loose/felt too easy to install).
- 11-Speed KMC quick link, perfecty smooth, and again, felt a little too easy to install.
I'll try to track down a KMC 12-Speed and/or YBN 12-Speed quick link tomorrow when the shops are open. I've let Peter know via email and am waiting for him to respond, but thought I'd bring it up on the forums too as a heads up (and perhaps others here have some suggestions which I'd really appreciate!).

I didn't even know Peter offered carbon chainrings too LoL. Thought it was just the cranks.

where are you ordering these? I went through the thread and am not seeing a product page.
-

Yeah they're the default carbon plated ones that you could get on aliexpress too. Doubt they make them themselves, just like the carbon spiders. I could believe they make the crank arms themselves because they look just different enough to everything else. All the metal parts of the spindle and crank arm interface are identical to all the other generic carbon cranks, so they could be buying those from CENIT who produce cranks for all the others.
-

Me neither! For the right price i'd order a 52/36 combo. Looks really nice :)
-
Forgot to test out one more thing: I forgot I had a 48T Alugear narrow wide 1 by chainring in my parts bin so I thought I'd put it on and see if it works with the 12-Speed Shimano quick link and yup! It's perfect. Saves 60g over the XMCS chainring too.
So just confirming that the XMCS narrow wide 1 by chainrings use a generic narrow wide tooth design which will not work with Shimano 12-Speed quick links (will not work with ZTTO 12-Speed chain quick links either, but not tested it with KMC or YBN quick links).
-
Hey Justin, did Peter answered your email ? I also ordered his carbon chainrings (52x36) and I only have a shimano chain.

Looks niiice! What Spacer come with the crank and what have you got installed on the bike spacer wise?
-

Peter must be super busy. He has not responded at all, but 100% the narrow wide chainring he sold me will not work with a Shimano 12-Speed quick link. The Alugear chainring is not only lighter, it's designed to be used with a 12-Speed Shimano HG chain and it's running absolutely perfectly.
Hopefully Peter addresses this with future customers as I now paid for a chainring that I am not using.
Looks niiice! What Spacer come with the crank and what have you got installed on the bike spacer wise?
A bunch of thin spacers came with the cranks but I didn't have to use any of them on either the drive side, or non-drive side.
PS: I've decided to not use the XMCS spider too. It's light, but the weave on it is 3K, which is different to the weave of the chainring. As a visual person this is like having a lounge room with furniture made from 5 different woods. The carbon weave on the ring, and carbon weave on the spider just don't match anything else on the bike, but I'm really happy with the crankarms, both the 155 length as well as how they look so they're staying on the bike!
I have a cSixx Raceface/Easton Direct SPEEDRING coming in the mail. They clearly state that it works with Shimano 12-Speed chains as well as SRAM flat top chains (and KMC chains). It's a heavy bastard, but it's a direct mount so I won't have to use the XMCS spider, or chainring bolts (fuuuuuu so good as I absolutely hate chainring bolts, so 80's!).

What do you think about the straightness of the chainring?
Had some challenges setting setting the front derailleur up.
Big chainring

PS: Here's a short video of the issue I'm having with the XMCS 1 by narrow wide chainring with a Shimano 12-Speed quick link. Whilst riding the bike, on load the quicklink gets VERY stuck in the teeth resulting in pretty hardcore chain slap.
Peter had his engineers look at my issue, and they failed to see any issues after their testing, which was videos of them rolling the chainring around on a chain fitted to another bike. IE: they were holding the chainring in their hands rolling it over the chain rather than actualy fitting it to a bike for testing.
He asked me for more photos, or a video of my issue, and whilst I was initially annoyed with their testing, and also having to take off my Alugear chainring to get their chainring back on my bike, to then shoot a video to send. I figure I'll be helping them further develop the product, or at least help them to give future buyers a warning when purchasing the chainring.
Peter has since sent this video to his engineers. Fingers crossed they actually further develop the chainring to work perfectly with Shimano 12-Speed chains (vs. suggesting to use a quick link from KMC/YBN etc.).

I have had this happen to another ring as well. I resorted to filing the teeth a little but it should not happen at all - and probably wouldn't with a 10 or 11 speed chain. I could understand with something cheap but spending this much I would be pissed. Does it catch on the "narrow" tooth of the ring as well ?
-

I'm not sure as I've taken it all off again now, but I'm assuming the easiest fix for this issue would be to find a 12-Speed quick link that will work. KMC, YBN, etc. Before splashing more cash on a bunch of different quick links I think I'll wait for a reply from Peter and his engineers.

Runs true with DA chainrings.
Need to reevaluate a proper way to measure the deflection.
Running into a slight issue with the crankset as well, let’s see how this turns out. (But need confirmation about crank bolt torque settings and there may be something with the pedal thread…)
-
My bike shop is having an issue fitting the cranks. I have reached out to Peter for an answe but he will be super busy with his new born.
The cranks are replacing Sram Quark that are torqued to 35 nm when fitting. But when the XCMS cranks are fitted and torgued beyond 15nm the BB gets compressed. My bike shop guy shakes his head and says he doesnt understand.Anyone had this issue or can suggest a solution?
Cheers
Bob

XMCS crankset now fitted with a Csixx direct cinch mounted narrow wide chainring (no need for spider or chainring bolts).

Can anyone who installed this crankset tell me if you put spacers either end of the spindle? My LBS installed it and found going beyond 15nm applied too much pressure to the BB. I don’t think they used the spacers
Thanks

No need for any spacers on a 2023 Cervelo S5 with standard BB and no spacers needed at all on a Tarmac SL8 either (also standard BB). Cranks spin very freely on both bikes.
-
Spacers installed and it’s fine.
Issue I’m having is that the crankarm bolt required a lot of torque to be fastened. (*way below 40NM)
Without that I think it becomes a bit loose during a ride.
I’m using motorex anti seize on the ends and in the threads. That’s correct right?
Now it doesn’t move anymore but there’s still the slightest clicking when applying inwards pressure on the crankarm.

I had sometime recently and it was pedals ;D so tightened as required to 20Nm. I would use a little Loctite. The Nm on the XM bolt is low compared to competition which is like 35-40Nm

How do you know the torque settings ? There is a text of 12-15 NM. But is that for the crankarm bolt or the lockring that is above (which has the actual number on it)
This also similar on the lexon crankset that I have.
I verified it’s not the pedal because I pushed on the crankarms themselves. But thanks for the suggestion
Is loctite on that bolt really that great of an idea? I thought you’d have issues loosening that bolt at some point anyways (hence the need for special tools)

40nm. Race Face suggests 50nm, but I didn't want to push it with a brand I'm not so familiar with, so 40nm for now, will keep an eye on it over the next few rides.

What's the final verdict then on the carbon chainrings? Shall I just stick to Shimano rings for now?

PS: Just been speaking to Peter from XMCS and thought it would be only fair for me to give a final report on the issue I was having with the 12-Speed Shimano quick link not meshing well with the XMCS narrow wide chainring.
Problem is solved with a YBN quick link.
IE: I tried 2 Shimano 12-Speed quick links, one used, one brand new and both did not mesh. I tried a ZTTO 12-Speed quiick link, it too was too narrow and did not mesh, but the YBN quick link works fine.
-

Depends if you really need the aesthetics.
Personally I would and will just keep using the DA rings.
Better shifting, less weight , price comparable.

Hey everyone,
last year I was happy with a wheelset from XMCS, so I was excited to try their new carbon crankset. I bought the 165mm crankset with a titanium spindle, a carbon spider, and 52x36 chainrings and installed it on August 15th.
During the install, I immediately ran into a major issue: the chainrings aren't perfectly straight. They have a noticeable wobble, no matter how I mount them (see also Had some challenges setting setting the front derailleur up.
). This made proper alignment extremely difficult and prevented me from following the standard Shimano setup procedure for the front derailleur. I documented the issues in some videos: https://www.youtube.com/playlist?list=PLpOdLtd9--n6iJWOi2Rnggwd_eTDubUag
I was able to get around the problem by setting up the derailleur so the chainrings wouldn't touch it while I was pedaling, but this is a major hassle. There's only a tiny sweet spot for the adjustment, making the setup process a huge pain.
I reached out to Peter at XMCS directly to report the issue. He advised me to discuss it here on the forums. So, here I am.
To figure out what was wrong, I tested the crankset with a set of Rotor chainrings. The wobble disappeared. This confirmed that the crankset itself and the spider are fine; the issue is with the chainrings themselves.
The chainrings feels like a "beta test" product. I expected much higher quality. If you're considering buying this crankset with the chainrings, I'd advise caution. You might end up with the same frustrating experience I've had.
I hope this helps!
-
Yeah was also advised to discuss this in the forum.
I just installed DA chainrings in the meantime to troubleshoot the crankarms.
And until I can objectively measure the deflection of the chainrings.
But I guess you confirmed my unit.
But I wouldn’t really know what to do. If the chainrings are not completely true there’s always a certain chainring orientation where there will be good shifting and otherwise nothing happens or the chain get dropped off.
-

I agree, this is far from an ideal situation. My "fix" of adjusting the front derailleur has made it somewhat rideable, but it's a frustrating compromise and not a long-term solution. I'm already looking into a replacement set of chainrings.
I'm also wondering why the chainrings look identical to those sold under the Leese brand on AliExpress.

They do look very similar but the leese ones don’t have the bolts. Whatever that matters.

Hi guys. How wide the assembly is?
Example attached to make the question clear.

Hi all, I have just got the crank, okay, yesterday ;D Looks amazing, the carbon fiber look really nice for me! The crank in size 165 mm for SRAM DUB weight 330 g, sometimes the weight showed 329 g. A bit heavier than Sram RED E1, but looks better (315g) 8). Weight with the 46t chainring, Xcadey power meter gen 2 and five bolts is 532 g. The whole installation and assembling was very easy, no issues at all! For now the Favero Assioma pedals will be installed, for the testing purpose. Due to GPLama content I promise to take my own tests and I will compare Elite Justo vs Favero Assioma Dup vs Xcade Gen 2. Regarding the crank, I will provide the feedback as well.
-
Asking for any new reviews from any here that purchased this crankset?
Thanks

Excellent. 165mm at 330ish g's. No issues on install on Sram dub. Look fab in the light.
-
Purchased 165mm Ti spindle cranks in October. Super sleek look and they're exactly what you'd expect from a crank. There's nothing flashy besides it being lightweight, if you like the look you really can't go wrong.
Just install the crank correctly and check if you need a spacer to ensure the easton cinch doesn't rub against the BB. I compressed my BB bearings because I just assumed assembly. Got it wrong and caused a few issues.
One BB later and all is good.
You should probably ask and purchase an extra pre-load ring if possible, you never know when that thing will break (if it does). Harder to find aftermarket 24mm spindle ones.
-

Hi, I'm using that with Xcadey spider and some ali chainring since 15th of December. In general, no issues, installation was very easy and quick, looking very good, the crankset is stiff, I'm very satisfied. Maybe that is not the lightest but for sure is solid. Lastly, maybe the preloader ring is plastic, that potentially could be some weakest point of the product. For now, I only rode indoor, so I didn't test it outdoor.

Hi everyone, I wanted to share a quick update on the XMCS 52/36 chainrings since they don't get talked about much these days.
Note: These are just my initial unboxing impressions—I can't install them yet due to an issue with my crankset, so I haven't tested the shifting performance.
For context, I had shifting issues with the first-generation version on my Ultegra 12-speed setup. This newly revised version shows some clear updates:
Visuals & Construction: The new chainrings look distinctly different (the new one is top/left in the photo).
Outer Chainring: The rivets have been repositioned, the back is no longer milled out like the original, and the crank arm opening has been reworked.
Weight: The design changes are reflected in the weight—the new pair comes in at 182.3g, compared to 198.9g for the old set (weighed on my kitchen scale).
Inner Chainring: The small ring now features a carbon finish. Interestingly, it's on the side facing the outer ring, so it won't really be visible once installed—correct me if I'm wrong on that!
While I can't speak to the shifting quality just yet, I’ll post another update once my crankset issue is sorted out. Overall, I’m really happy with how constructive the process was and it’s great to see the brand making tangible revisions.
