Hi everyone,
Wanted to share a bit about a new wheelset I’m having custom built through a lesser-known OEM in Xiamen called Zen Carbon. Thought it might be of interest to anyone exploring beyond the usual big players like XM Carbon Speed or Elite.
Background
I’ve been working with a few OEMs this year. Back in April, I ordered a 60/65mm carbon spoke set from DFS Carbon, which came in at 1230g and has performed really well so far.
I’ve also got a set of 50/60mm carbon spoke wheels on order from XM Carbon Speed — very popular on here and on Weight Weenies. The rims are still in manufacture, but I’ve been told they should be completed this week.
This new set is coming from Zen Carbon, which doesn’t really have any online presence. It’s a small company based in Xiamen, run by Zara and her father.
Why Zen Carbon?
I’ve known Zara for a few years — she was my contact back when I was buying Winspace products (frames, parts, etc.) around the time when Jo Whittingham (of Panda Podium / China Cycling YouTube) was still there. I’ve had access to dealer pricing from Winspace, and Zara was always super helpful. She moved on to Zen Carbon a couple of years ago, and while I hadn’t ordered anything from her since then, I thought I’d give them a try for this build.
Wheelset Specs
• Rim depth: 40mm front / 45mm rear
• Rim width: 31mm external / 25mm internal
• Rim weights:
• Spokes: Carbon, 2.1g per spoke
• Hub: Zen SL 20H front & rear – 226g total
Pricing
• Total: $866 USD / ~£670 GBP to the UK
Would love to hear if anyone else has experience with Zen Carbon or the H-Works hubs — or thoughts on using mixed-weight rims like.
25mm rims sizes pictures obviously they offer more rim types

thanks for that. glad you have this forum to post in to save the snarky responses in WW.

Appreciate the feedback, Serge — but this definitely isn’t a vanity project.
The DFS wheels I previously bought were a bit of a punt — small brand, relatively unknown — but with a 90kg rider limit, they were within spec for me. I took the chance, and they’ve been excellent so far. At 1230g for a deep aero set, they’ve really delivered.
The 50/60mm wheels I ordered from XMC (via XMCarbonSpeed) are still on the way — haven’t received them yet. Their lead time’s a bit longer, but hopefully I’ll get a message next week saying they’re ready to ship. I went for them as a solid all-rounder to replace my older Craft Racing Works wheels. I sold those because the rear had a 21mm internal width, which wasn’t ideal. The XMCs have a 24mm internal front and rear, which better suits modern tyres, and they’ve built up a strong rep for quality and performance. Peter from XMC estimated the weight at around 1200g, which is impressive for a wheelset in that depth range.
The 40–45mm wheels I’m building now are more of a climbing-focused setup. I considered going shallower and even lighter, but for me, performance always comes first — the gear has to work. I didn’t just go for the lightest version of these rims either. I wanted a more balanced setup, particularly with durability in mind. Adding 40g to both front and rear rims raises the system weight limit to 110kg, which is the same approach Light Bicycle takes — slightly heavier at the rear for strength, lighter at the front. In my case, I opted for the reinforced rear only, since that’s where most of the load goes. At 77kg rider weight and with the SL8 at 6kg plus about 2kg of bottles and tools, I’m still well within spec.
I also put up a thread on Weight Weenies about lightweight Chinese hubs to see what’s out there that could genuinely compete with Western brands like Tune, Extralite, Tactic, etc., without spending €1,000+.
All in all, I spent a good couple of weeks researching before committing. Light Bicycle was a solid option — their 45/45mm wheelset is advertised at 1063g with a 110kg weight limit and comes in around $1,500 USD delivered. In comparison, these came in at $866 USD delivered (about £670), including hubs, which I felt was excellent value for the spec. Now it’s just a case of getting them built and seeing how they ride.

You've clearly done your homework. When i say vanity it's not directed at you, it's a general idea. Virtually everyone will be better served with a slightly heavier, more reliable / durable hub than the opposite.
You specifically enjoy geeking out on very exotic gear, so it makes sense you'd go for such kit.
But durability, failure rates, tolerances going out of spec, aren't think that are well understood and tracked, so generally, i'll go for proven hubs and spokes, because i'm playing a probability game, and would rather lower the chances my wheels start acting up. All the more if hitting potholes and the likes. Or if you go do a cycling block somewhere, or a bike packing trip, and start worrying if your wheels are going to cause you issues.
There's untold value in stuff that just works, that's all i'm saying.
Thanks, Serge—I really respect what you have to say, and I totally get the value of proven, reliable gear, especially when durability and failure rates matter so much out on the road or trails.
That said, as I mentioned, I could have gone for the lightest rim option, but I chose to increase the rear rim weight by about 40g to raise the rider weight limit where it actually matters—on the rear. It’s a practical trade-off for strength and durability.
I also really appreciate that Zen is taking the time to carefully consider what I want and is actively engaging with their engineer to get the technical details right. For example, they even asked me where I wanted the drain hole—normally it’s placed on the non-drive side above the valve hole because they’ve determined that’s the best spot, so I went with it. The engineer confirmed this is a 1:1 spoke pattern hub with no dish, and to improve lateral stiffness, the rear rim will be asymmetric. Even though the hub is symmetric, the asymmetric rim helps balance spoke tension and overall wheel performance.
I’m not an expert by any means, and I’m certainly getting an education through this process—listening closely to everyone’s thoughts and opinions.
Remember, every tried-and-tested design had to start somewhere, so in a way, I’m a guinea pig here—but I’m definitely not a risk taker. Obviously, I don’t want anything to go wrong either, so I’ve looked at this thoroughly, and the risk I’ve taken with this setup works for me. That’s why I’ve done my homework thoroughly on this wheelset in particular.
Innovations like this often start with thoughtful engineering and testing—just like the HX hub did. So while I respect the importance of tried-and-true setups, I’m also interested in well-designed advances that push things forward without compromising reliability.

Thanks Stephen for this new discovery.
Is there any website we can check the wheels? Or a way to contact Zara?

Rim Weight vs Rider Limit
Zen Carbon confirmed that rim weight directly affects rider weight limits:
• 320g / 340g rims = 90kg max rider weight
• Add 40g per rim and that increases to 110kg max rider weight
Do they actually mean rider weight or system weight? Usually, I see system weight (as in rider + cloths + bike + gear/tools) mentioned as the weight limit. Just checking to avoid misunderstanding.

Haha yeah, I’ve actually been dealing with Zara through Instagram DMs
Here’s their Instagram: https://www.instagram.com/zencarbonbike?utm_source=ig_web_button_share_sheet&igsh=ZDNlZDc0MzIxNw==
Website: https://zencarbonbike.com/ — but honestly, it’s not great and definitely not up to date. They focus more on OEM, so a lot of the rims and options (like mine) aren’t even listed.
If you want to reach out, best way is to message directly or useinfo@zencarbonbike.com
WhatsApp: +86 15160726618 / +86 13218277787
Although I’ve posted a thread, I wouldn’t call it a recommendation just yet, since I haven’t actually received the wheels. For now, I’m just highlighting the process and how it’s been going.
So far, I’d say the value is great and the responsiveness to messages and questions has been really impressive. I get the feeling Zara’s handling a lot of enquiries, but even with the 7-hour time difference (I’m in the UK), she’s been replying late in the evening on China time, which I really appreciate
I’ve also let her know that I’m posting about the process of ordering these wheels on both Chinertown and the WW forum, just to keep things transparent.

Apologies have updated that to system limit

I also recently ordered a set from Zen. Went with a 50/60 combo, have attached full specs. Looking forward to getting them shipped to me here in the Midwest US soon and putting some GP 5000’s and many miles on them.

Hey Joeynailz,
Good to hear! How was your buying experience — did you deal with Zara?
Nice spec! That’s a really light setup too.
How much did the wheels cost, and when are you expecting to receive them?
-
That's some bling on the freehub! Too bad you will never actually see it once the bike is built ...

How much for that built if you dont mind me asking?
-
Interested. Have a 1300g set of 50/65 xm's that I'm happy with, but wouldn't mind a set of climbing wheels for mountain days.
-
How much for that built if you dont mind me asking?
Yeah no problem. Total was around $750 USD, shipping included.
And did most of my communication with them over the IG page. Went back and forth over specs and finishes for a couple weeks before getting an email invoice and paying with PayPal.
Hoping to receive the wheels in 2 weeks or so.

Great to hear — sounds like a really positive experience! That’s incredible value in my opinion — CBK would be around $800, not including shipping. And a two-week turnaround is excellent! 😄
I’ll admit I’m a little jealous of the weight though 😅 — 1120g is seriously light compared to my 50/60mm XMCs at 1194g. But to be fair, mine have a 120kg rider limit, so that extra 40g per wheel (they’re sold as 1200g) translates into the added strength for the higher weight rating.
I won’t lose any sleep over it… maybe just a little! 😄

Yes the lot mate.
Look at joeynailz posts above on this thread he has got a set of 50/60 wheels all in for $750usd.

@Sander2177
Thanks so much for this finding.
I am going to make an order this next week for two set of wheels. One in 45s and second one in 50/60 combo. Both with the sr270 hubs.
Hopefully these wheels get on well with the Irish roads (not the best).

Well, I have a Brit and Irish passport, I’d say there’s definitely some competition when it comes to the sh*ttiest roads! 😂
Happy to help, mate. I don’t get any kickbacks, but if you end up messaging Zara, let her know you read my thread on the forum.
Would be great to see Zen get some positive feedback—maybe they’ll even start posting on the forum themselves.
From my experience, I’d definitely recommend them. They’ve been really responsive, and right now their 14-day turnaround on wheels is impressive—probably helped by the fact they’re still a relatively small operation.
-
I spoke with Zara from Zen—she may be posting on the forum soon. But for anyone interested in the meantime, here’s some useful information:
• ✅ Rim specifications, including rider weight limits and individual rim weights
• ✅ Carbon spoke weights
• ✅ Example pricing for a 50/60 mm wheelset
These wheels are built with the H-Works SR270 rear hub
https://h-works.cn/products/hw-261-rear
3.95 mm or 5 mm carbon spokes, offering a high-performance, lightweight setup ideal for road disc builds.
Price varies obviously depending on rim carbon type
Shipping is offered with taxes but you will need to contact for prices for your own country!

No worries always happy to help fellow forum members :D

Interested to see what you think back to back with the carbonspeed wheels after these arrive.
-
he has the data points to go back to back to back between DFS / XM / Zen. and possibly memory compare to his former CRW's too.

All very different wheels for different scenarios.
The DFS wheels are my full-on aero set — 60/65mm — and they’ve been great for holding speed and general road feel. In gusty winds (up to 25mph), the front gets a bit twitchy, which is expected at that depth. They handle it reasonably well, but the sidewinds are definitely noticeable.
The XM CarbonSpeed wheels (50/60mm) are more of an all-rounder. They arrived yesterday, and I took them straight out for a 100km ride — around 50km of that was in a chain gang averaging 37.8kph. Not exactly a scientific test, but they definitely felt rapid.
What really stood out was the ride quality — stiff, responsive, and solid under load. They also have a noticeably more premium feel and finish compared to the DFS wheels although both Matte UD Paintless the DFS are shinier and the XMs are more matte.
The build quality just feels that bit more refined and premium on the XMs
CRW rate their wheels to 100kg, while the XM CarbonSpeed set is rated to 120kg — that extra stiffness is noticeable when putting down power. The 24mm internal width on the rear (vs 21mm on the CRWs) adds comfort too.
Overall, really impressed — stable in the wind, fast, and a very nicely put-together wheelset.
Will be interesting like I said to see how the Zens shallower wheel performs
-
my kid picked up a pair of 8lien L6 wide's for his build, i'm eager to try those out (34mm outer / 25mm inner / 60mm deep). i'm running 45's on my SL8 and have actually been super happy with that depth. i run 65's on my Madone. No hills where i live in Florida so wind is the beast that makes up for them. the 65's were always fun in low yaw but in high yaw heavy crosswinds it could feel like i was dragging a sack of potato's behind the bike when the wheels stalled. none of that feeling on the 45's which honestly i see as a net win.
-
Quick update on the 40F/45R wheelset I ordered from Zen Carbon…
Zara has just sent through the finished build photos and I’m happy to say they’ve come in under the magic 1kg mark — final weight: 993g 🔥
Really pleased with that — the original estimate was 1010g, so to see them sub-1kg fully built is a great result. They’re being shipped out today, so fingers crossed for a smooth 8–13 day delivery.
Looking forward to getting them out on the road and seeing how they ride — I’ll follow up with a first impressions post once they arrive.
That is spectacular pair of wheels! Pictures look very pro too! I'm waiting for the first impressions and I would like to order some 45 mm deep wheels too. Maybe H-works will supply this HX hubs to the public soon.
-
do you have an idea of what the maximum outside width of the Zen rims is? it indicates 31 at the brake track, but appears to get a little wider at its midpoint. pondering doing a set in 50/55 and move my 45's to my gravel bike.

Yep, those 24mm internal rims — that’s actually the outside diameter you’re seeing. Picture this: 34.15mm external, and then you’ve got some rims going up to 50mm deep with a 25mm internal width, and even others with a 29mm internal.

Some familiar design cues on those hubs, guessing <260g?

Hey Toxin
I think it’s just the H-Works SR270 in different colours will ask.
But your almost there was told 270grams
-
Those are most certainly not SR-270 and not made by h-works. I'd bet a lot that they come from the same factory as this https://aliexpress.com/item/1005007809725803.html

All the hubs look so generic and the sen but you’re right. Had a look at AE and these are coming in at 270grmas in a photo which is what ones told.
Have a look at the new Enve hubs on today’s 4.5SES release. 280g look generic ans well like they could be from China

Hi Toxin,
The hubs are from a factory in Guangzhou. They’re not exactly the same as the ones in the link you shared as they are 24hole, but when I did a reverse image search, I found a lot of hubs that look very similar. but cannot find anything 20 hole yet. That said, I haven’t come across an exact match yet, but they could be but machined to give a slightly different look
I’ll continue looking into hub manufacturers in Guangzhou — there are likely quite a few, so tracking down this specific one might be a bit like finding a needle in a haystack.

Got an update last week from Zen, my 50/60 set came in at 1121g.
Looks like they arrived at US customs on the 5th. Hoping they show up some time this week...

Crazy weight!!
Not seen any post myself for 50/60s in the 1100g range I have seen a set at 1099g but not seen any release info yet plus they wont be as well priced as the Zens
She send any pictures you can post need to stick them up on WW ;D
My wheels are making there long slow journey the UK :-\

UPDATE
Just a quick update — the 40mm front / 45mm rear wheelset I ordered from Zen Carbon turned up today!
🛠️ Production time: 20 days
📦 Delivery time: 10 days to the UK
I’ve got to say — I’m super, super impressed.
The build quality looks fantastic look and feel premium the finish is spot-on, and the overall service was excellent from start to finish. Communication was clear, fast, and helpful throughout — Zara at Zen has been absolutely brilliant to deal with.
In the box:
✅ Tubeless rim valves
✅ Four spare spokes
✅ Rim tape (which I was about to order separately — nice surprise!)
✅ And the wheels themselves were really well packaged, with a cling-film style wrap that kept everything secure and protected — similar to what I had when I bought my CRWs.
Firts impressions are excellent considering the excellent value for money
Hopefully they ride as good as they look!

After going through this thread I contacted Zara and have been messaging back and forth with her on instagram. She's been super helpful and quick in her response.
55/60 light weight rim with UD Gloss finish
Carbon 3.1mm spokes
SR270 Hub
Expected weight: 1300gr
Price: $785 incl shipping and pre-paid taxes
wheelset should be coming in 2/3 weeks (Netherlands)
A little leap of faith in regards to the quality (given the lack of references on this company), but the first impression is promising.
-
Looking forward to your riding impressions. I personally feel that - at least for an allround wheelset - there comes a point when it is just too light. Because as great as it might feel when riding uphill, superlight wheelsets have so very little momentum when riding fast for a long time on flat roads, that it feels a bit dragging (for the lack of a better word). Like you need to constantly push them to keep rolling. It might not even show up in the numbers and riding stats. It’s more a feeling. If I know in advance that I’m going to ride predominantly flat terrain, I prefer a heavier wheelset.
But don’t get me wrong: light wheels are a ton of fun!

Yeah, I get where you’re coming from — it’s definitely a bit of a leap of faith. Buying wheels right now isn’t easy with so many companies out there. Even on this forum alone, you’ve got brands like Serenade, Carbon Bike Kits, and others all essentially offering the same thing.
For me, it really comes down to finding the right balance between quality, reliability, and service. One of the biggest things when dealing with OEMs is how responsive they are and what their customer service is like. Some are honestly terrible, while others have been great — and that really matters, especially to Western buyers.
So far, my expectations have been met. Sure, I’ve still got to ride the wheels and see how they actually perform — and look, who knows, I might get on them and think they’re noodles! I’m fully aware that could happen, and I’m fine with that risk.
But at the end of the day, most of these sellers are offering very similar setups: H-Works hubs (or similar), carbon spokes, and a U-shaped carbon rim — whether it’s 24, 25, or 26mm wide. It’s all variations of the same formula.
So I’m not expecting these wheels to perform worse than anything else I’ve ridden. Time will tell, but so far, so good

@Sander, have you mounted some tires on them yet?
I'm not sure which width to go for. I want to go as big as possible, while staying within the external width.

Hey NB87,
Not yet — I’m not sure I’ll get a chance this week as I still need to tape the wheels and pick up some brake discs.
I’m running 28mm Maxxis High Road SLs. My current XM Carbon Speed wheels are 50/60mm deep with a 24mm internal width (and similar external), and those tyres measure 30.7mm when mounted.
The internal width on the XM wheels is 24.46mm (F) and 24.25mm (R), while the Zens measure 24.73mm (F) and 25.11mm (R). So I’m expecting the tyres to come out about the same, maybe slightly wider.
Personally, I think a 30mm tyre is about the max I’d go for on these rims — 32mm would I think start to give that “lightbulb” shape.
Also worth noting: not all tyre brands are true to their labelled width. Some run narrower or wider than stated. If you’re unsure, I’d suggest buying 28, 30, and 32mm in your preferred brand, mounting them up, measuring, and keeping the one you’re happy with. Just return the rest.
-
Cheers for the input. I'm aware of the (possible) difference in width between brands.
A 28mm tire measuring up to over 30mm is a good indication though especially with a similar rim profile.
In that case I'm thinking 28mm in the front for optimal aero, and 30mm in the back for that extra bit of comfort. But let's see how it all sizes up when they're mounted :)

"However, for new orders, Zara mentioned that it might be possible to obtain the HX hub — which is more expensive — if enough demand is generated to meet the MOQ of 50 units. "
I'd be up for this. Waiting for your impressions on the build!

Been busy and have not managed to set up the wheels yet and I’m away this weekend as well.
Planning to get out next week!

i'd be interested in doing that. i want to build up a 50/55 set for all round use that can meet or beat the weight of my 45's. shouldn't be too difficult - they're 1190g
-
Peter built me a set of 50 deep, wide rims, steel bearings (they weigh more), off the shelf stuff (no exotic hubs where you have to ask yourself if you're too fat :D), 1200g. So 1200g is now an "easy" target. Which is ironic because the latest release of the german Lightweight, which is supposed to be the pinnacle of german engineering... weighs 1200g (as per a GCN video from yesterday).
These ultra light hubs, are they as reliable as others and suitable for fat arses? 50g for 73$ doesn't sound unreasonable, especially considering the price of a starbucks coffee. If you're going to ride these wheels for years, that extra cost can be reasonably amortized. BUT, and that's a big butt (yes please), are the hubs for regular humans and are they as reliable as their more off the shelf counterparts? I have 15,000km on my set of Peter's wheels, and i expect them to keep rolling, i dont want my wheelsets to require constant baby sitting.
Honestly, Serge, I can’t give a definitive answer — only time will tell!
This ultra-light option is for those who want to save weight, which seems to be everyone’s goal these days. But it’s worth keeping in mind that with these super-light components, durability and longevity can sometimes be compromised.
Everyone’s priorities are different. If longevity and proven reliability are your top concerns, then sticking with a DT Swiss 240 hub is a solid choice.
Personally, I’m always swapping and testing equipment myself, so I get the trade-offs involved.
-
Farsports’s do this hub there wheels is 50/55 are $1567usd 1065g +/-30g 120kg limit
Gold weight and rider limit but double OEM prices
i'm not light but i have no problem being under 120kg as a full system. rider + bike + kit + accessories + minimal tool kit is ~89kg +/- 0.5kg. add max 2kg to that for a pair of full 950ml bottles.

That rider limit is great — a nice big margin, just like the XM Carbon’s 120kg.
The ultra-light gear is awesome, but no one has really managed to push the weight limit beyond 90kg for those crazy light setups. I’m probably around 85kg once you add my bike, bottles, and toolkit.
My 90kg-rated DFS wheels are holding up fine. They say 90kg max, but I was told they can handle closer to 100kg. Most OEMs don’t usually share that kind saftey factor
-
I think you mean safety factor not error.
If you want to be a weight weenie but find youself concerned with the specified rider weight limit of a wheelset, you should instead go on a diet
You’re right — I meant safety factor, not margin of error. Thanks for the correction, even if it came wrapped in unnecessary attitude.
As for the diet comment… I’m 75kg at 12% body fat with an FTP over 300W. I think I’m okay.
Maybe next time skip the condescension — you might find people respond a bit better. Just a thought.

Maybe next time skip the condescension — you might find people respond a bit better. Just a thought.
Pogi approved your post ;).

If you want to be a weight weenie but find youself concerned with the specified rider weight limit of a wheelset, you should instead go on a diet

Zen wheelset came in the mail today for Gina's Tarmac SL8!
Whilst Zara’s communication was often instant, she never gave me updates on the wheels without me prompting her first, nor tracking information (only when I asked did I get the tracking information).
The wheels took a month to get here, they were boxed well (came with spare spokes, rim tape and tubeless valves) and they look amazing. The included rim tape was trash so I used Schwalbe tubeless tape instead (much more elastic and easier to apply). At 1058g a set they’re 513g lighter than the Roval C38’s (which are also a shallower at 38mm front and back). I fitted a Conti 29C Aero 111 to the front, 30C GP5000 ST R to the rear with RideNow 19g TPU tubes and Gina’s bike now comes in at 6.3kg’s.
PS: Forgot to mention. I've never had to use a tyre lever to get tyres on a wheel and I've had all sorts of wheels and all sorts of tyres. These are used tyres too so it should have been even easier, but nope. Had to use a tyre lever to get the last bit on, on both wheels.
PPS: Much thanks to Sander7721 for all the research and help with making this happen!

bike looks awesome! i'll be interested to see how she gets on with that ZTTO cassette. I have an e.dubied & co. monoblock steel cassette on my SL8 in an 11-26 size. lovely piece of kit and very light but it will hang shifting up into the 19t sprocket and no amount of adjustment to the b-screw and micro-trim can remedy it. i have considered swapping it to an 11-30 since the 11-26 is out of spec.

@JustinFox
If you know:
1) Did they have to come with Zen decals?
2) Did you ask them to install the tubeless tape for you?

Yup have to admit that you really do need to spend the time to adjust these Gen 3 ZTTO cassettes to get them shifting right, and even then they're louder than the standard Shimano cassettes (at least the 12-Speed Gen 3 is but the 11-Speed with a 12-Speed chain is dead silent on my SL6). All good when the chainline is good, but definitely louder when you're on the small cogs in the big front chainring.

Pretty sure I'm the only person in this entire thread that has specifically asked for the ZEN decals and no I didn't know I had to apply the rim tape myself (I totally forgot about this and if it was an option I would have gone for no holes in the rim bed).
Forgot to mention in my post; the end caps come off these wheels SO easily! The wheels come packaged with protective plastic caps and when pulling these caps off the end caps came right off! Definitely a lot looser tolerances than Roval or ENVE wheels, both of which had very tight fitting end caps that I struggled to remove (I have no vice). Not sure if this is a thing to be concerned about, but just something I noticed.
-
They're H-Works hubs right? Normally they can be trusted to know how to build a hub. Loose endcaps could present a problem like Peak Torque had with his first CRW set. As the rider who will be riding these is probably half his weight, it's unlikely to be a problem.

I just got the standard hubs they offered. "Zen SL hubs". Ratchet system and lots of thick blue grease. Rider is 50kg's so should be OK. I'll keep an eye on them.
-
I think I recall someone saying that Hworks had their name etched onto the axle of the hubs. Might be worth checking if you're curious. Were the end caps greased where they sit on the bearings? The Hworks hubs my BTLOS wheels came with plenty of grease to help keep dust and dirt out of the bearings.

No need to take them apart, you can tell from looking at the shell. The angles in the pics are quite poor for it though.
-
True, they do have a very unique shape to them. Better pictures would tell us as well.

Yes
Most OEM use consolidated shipping hence why you don't the package in like 3/4days as this is possible
If you don’t known how consolidated shipping works:
Consolidated shipping is a logistics method where multiple parcels — often from different sellers or suppliers — are grouped together and shipped as one large bulk consignment. Rather than each parcel being sent individually (which would make each one subject to its own shipping charges, customs declarations, and potential import taxes), they are “consolidated” into a single shipment and moved through international borders as one.
This method is commonly used by freight forwarders or third-party shipping agents, especially for goods coming out of China. Here’s how it typically works:
1. First Leg – Domestic Transit in China:
Your items from different suppliers are sent to a central warehouse or consolidation point in China (e.g. in Shenzhen or Guangzhou). They are held there temporarily while other packages arrive.
2. Second Leg – Bulk International Shipping:
All the packages are then grouped together and shipped as one container or pallet to an intermediate country (often Belgium, the Netherlands, or Germany). This shipment is often done under a different tracking number — it’s not trackable like standard express shipping (e.g. DHL or FedEx) during this leg.
3. Final Leg – Local Delivery in Europe:
Once the consolidated shipment arrives at its European hub, it’s unpacked and the individual parcels are handed over to local couriers. At this point, each parcel gets a new local tracking number and is delivered to its final destination.

When are your wheels due?
-
At 1058g a set they’re 513g lighter than the Roval C38’s (which are also a shallower at 38mm front and back).
Great looking bike and wheels! Do you mind sharing the wheel specs? Model name, rim, freehub, spokes, etc?

I'm no expert on these. I just went with what Sander suggested keeping in mind I could go a little lighter as Gina is 50kg's.
-
When are your wheels due?
They've entered the EU this week so guessing I should be getting them next week.
Zoe couldn't get them shipped by air due to the size (two pairs of wheels) without having to pay extra for custom and taxes.

Ahh ok that's good to know.
I'm assuming it was obviously cheaper to ship together, would it have been much more expensive to ship them separately and How much longer then to ship together what was the estimate?
-

|There is no model name as is a bespoke build from Zen
I believe this is the spec below for Justin's which follows mine just a different hub
Rim Front: 40mm depth, 320g, Ultralight layup (rated for 90kg system weight). Realistically, this layup suits riders up to ~75kg once you factor in bike, bottles, and gear.
Rim Rear: 45mm depth, 380g, Superlight layup (rated for 100–110kg system weight — for reference, Craft CRW rims are rated to 100kg). My spec includes an asymmetric rear rim to help balance spoke tension and improve lateral stiffness. The superlight layup also helps with responsiveness during out-of-the-saddle climbing and increase stiffness on rear as well
3.1mm carbon spokes, 2.1g each including nipples — total spoke weight is 84g.
HG freehub for Shimano.
I believe Justin’s wheels came with the H-Works SR-270 hubs, which are 276g.
Estimated total wheelset weight: ~1060g
There’s always going to be a trade-off between lightweight wheels and stiffness.
You could go all-out and get these wheels down to around 970g, especially now that Zen offers the lighter 226g hub as part of their builds.
Back when I ordered mine, I had to source that hub myself and send it to Zen.
But let’s be honest — there’s no point chasing 970g if the wheels don’t perform.
If you're aiming for these wheels to be more of an all-rounder rather than climbing-focused (100kg limit) , I’d suggest:
- Front Rim: 40mm Superlight layup, 360g
Rear Rim: 45mm Superlight layup, 380g, asymmetric (you won’t notice the asymmetry once built)
Spokes: 3.95mm carbon spokes at 3.5g each including nipples
Hubs: Zen Superlight hub, 226g, 20/20 spoke count
1106g estimated if you want the 3.1mm spokes then 1050g
This setup gives you a nice balance of weight, stiffness, and durability — without compromising ride quality.
Whats is it your looking for in regards to wheels? all rounder/do it all? climbing? aero?

Ahh ok that's good to know.
I'm assuming it was obviously cheaper to ship together, would it have been much more expensive to ship them separately and How much longer then to ship together what was the estimate?
Good questions there. I think it was cheaper for them and because I was in no rush to get them, I went along with it.
For disclosure, I paid 1.5k USD for the two sets. USD/EUR FX rate was brilliant at the time so got them under 640eur each.
She said it'd take 28 days to get over to Europe and so far it is looking that way.
I'll post some photos once they get on and give my first impressions.

That is good value around £550 a set.
Cant wait to here your thoughts and obviously see the goods ;D
Another David has posted his 55/64mm combo on WW with gloss finish, now I have a bit of wheel envy going on now as the gloss over UD looks lovely

Yup have to admit that you really do need to spend the time to adjust these Gen 3 ZTTO cassettes to get them shifting right, and even then they're louder than the standard Shimano cassettes (at least the 12-Speed Gen 3 is but the 11-Speed with a 12-Speed chain is dead silent on my SL6). All good when the chainline is good, but definitely louder when you're on the small cogs in the big front chainring.
I really like my gen 2 12 spd, but thank goodness wheeltop allows individual gear tuning, as its reluctant to downshift cleanly from 6/7/8 without some tuning. Once done it shifts as well as anything, but yeah, its as loud as a Sram x cassette, understandable as its hollow.
-
Whats is it your looking for in regards to wheels? all rounder/do it all? climbing? aero?
Thanks for the detailed answer! I'd be looking for an all-rounder set, but leaning slightly more towards climbing/lightweight rather than aero - so around 40-45mm deep rims. Don't actually need a new wheelset, but these weights make it very tempting ;D
-
I am very thrilled about these wheels. Please advice which configuration would better suit me.
1. I am lightweight rider 56-57kg with 280w on FTP. My sprint values however are just average and I can do about 1000w in the sprint.
Climbing - 50% in the saddle, and 50% out of the saddle.
2. I am riding 60% indoors, 40% outdoors and my descending skills are mediocre. No criteriums, only may be a few alpine marathons a year.
3. Current wheels choice: Hunt 44 Aerodynamicist, with steel spokes about 1460gramm a set. Even with this set descends can be very "windy" for me.
4. What I am looking for: May be a same stability or better in the crosswind, depth 40 or 44mm ( not ready to go 35mm just yet) and shave some weight.
I do not like when the wheel does feel not solid and occasionally I ride through the potholes ( if it is safer due to the riders, cars etc..)
Which rim / hub / depth configuration will you advise? How does these wheels compare to CRW and does it worth to overpay for them ?
How long are shipping times to Germany and the duties?
Looking at the official website I have not found anything similar discussed in this thread. How do you do the order and your payment method?
Thanks!

The last time I spoke with anyone, who bought a set of Zen wheels, the manufacturing time was about 15 working days. Shipping, including taxes, took around 10–15 days.
As I’ve mentioned, and as discussed in this thread, Zen is an OEM manufacturer, not a retailer. Their website often isn’t fully up to date, so it’s best to contact them directly via email or WhatsApp for the most current information.
I can’t directly compare these wheels to CRW, but I do have a pair of XM CarbonSpeed wheels in a 50/60 configuration. I sold my 50/60 CRWs to buy those, and I’m extremely happy with them.
From what I’ve seen and experienced, if I were spending money on wheels again tomorrow, I’d still choose a set of Zen 40/45s over CRW, mainly because they’re almost half the price. That said, the CRW hub—with the spoke directly threaded into it—is very well designed, but that alone isn’t enough for me to prefer CRW wheels.
Advising others on which wheels or configuration to buy can be tricky. Obviously, if you buy a set of CRW 40/45s, the choice is straightforward, but a like-for-like setup for Zen wheels would be…
CRW wheels have a system limit of 100 kg, which aligns with Zen’s superlight layup.
Although, based on your weight, you would also be well within the limit for the ultralight version at 90 kg.
Superlight
40mm rim front 360g
45mm rim rear 380g now as I’m a heavier rider and to help balabace spoke tension in the rear I opted for an asymmetric rear rim this also helps with lateral stiffness. Now you don’t notice the asymmetry when the wheels built also most wheel brand will not do this as it means an extra wheel mold. For example Extralite do asymmetric front and rear. At your weight though you should be ok with a regular rim profile it’s up to you or speak with Zara at Zen she may ask the engineer who is her father who owns the company.
3.25mm carbon spoke 40 number including nipples 136g
HX Hub 20 spokes from and rear 226g
Zen Wheelset estimated weigh 1102g
CRW Generation Wheelset 1180g (21mm internal width)
CRW 2025 wheelset 1140g (24mm internal width)
That said, if you often ride through potholes, hitting any pothole hard enough on a carbon wheel isn’t ideal—damage can happen regardless.
If you want something sturdier, you could choose the lightweight layup, which adds about 40g to the wheelset, bringing it to around 1142g—comparable to the CRW 2026 wheels.
Or you could opt for the standard layup, which adds about 80g, making the wheelset roughly 1182g. That’s on par with the previous generation CRWs and still considered lightweight!

Attached are examples of steel-spoke road wheels.
Gravel Wheel Options
Gravel wheels can be made lighter by choosing different rim layups. Here's a breakdown of the 35mm and 45mm profiles:
35mm Profile
Lightweight: 380g per rim (see attached photo), system limit 135kg
Superlight: 355g per rim, saves 50g per set, system limit 100–110kg
Ultralight: 315g per rim, saves 130g per set, system limit 90kg
45mm Profile
Lightweight: 420g per rim, system limit 135kg
Superlight: 395g per rim, saves 50g per set, system limit 100–110kg
Ultralight: 355g per rim, saves 130g per set, system limit 90kg
Lighter layups do increase cost slightly. Superlight is around $40 USD extra, Ultralight about $80 USD. Best to check with Zara for exact pricing.
There’s also a lighter hub option for carbon spokes, which could save another 50g if suitable for gravel. I’ve asked for a cost example using Berd spokes. If they can offer it at a sensible price, I might try it on a road set myself.
45mm Lightweight Rim 420g per rim per attached 135kg limit
35mm Superlight 395g per rim saving 50g per set 100-110kg system limit
35mm Ultralight 355g per rim saving 130g per set 90kg system limit
Lighter layups will increase the cost a touch think supwrlight is like $40usd and ultra $80usd but anyone intretsed would be best to get Zara to confirm obvioulsy
Lighter hub available for carbon spokes another 50g saved if suitable for gravel
And I have askde for a cost example with Berd spokes.
If they can do Berd at a sensible price consider giving that a go on a road set myself maybe.

How does these wheels compare to CRW and does it worth to overpay for them ?
I'm very happy with the 40/45 ZEN Carbon Bike wheelset that Sander helped me to order from Zara. They're cheap, very light, and look good, but I have a set of the 2026 CRW 4045's too and side by side there just is no comparison when it comes to appearance.
The CRW's just visually look so much better. Thicker carbon bladed spokes look killer, but more importantly LESS spokes on the front wheel make them look truly unique (and they sound unique too!). And side by side the CRW's just give off a much more classy/expensive/better quality look vs. the very understated ZEN wheelset.
All that said I'm very happy with both wheelsets, and for the money I'm considering another ZEN wheelset (50/60) for my Cervelo S5 over CRW's because my main gripe with the CRW wheels is that their hub is way too quiet to be considered obnoxiously loud!

I also have my 40/45s, and I’m really happy with them.
I haven’t posted much about the wheels yet—this month’s been hectic, and I haven’t had many chances to ride, let alone ride them properly.
I’ll try to post some photos this weekend if I get the chance.
One thing I would say: if I could go back, I’d opt for a gloss finish over the UD Paintless. Another guy on the Weight Weenies thread posted his 55/64s with a gloss coat, and they look fantastic.
The finish on mine is the same as my XM CarbonSpeed 50/60s—more of a satin look—but I think gloss would really elevate the UD Paintless aesthetic.
I’m also considering another wheelset from Zen for winter training here in the UK—something like a 60/60 build with Sapim CX-Ray Super spokes and brass nipples to handle the typical grim weather, also another excuse to get another set oof wheels ;D
Have a look at the Zen thread on Weight Weenies as well if you have not already.

Ditto. As soon as I saw the ZEN wheels in gloss I knew I made the wrong decision lol.
I think ZEN is at the top of my list now for a lightweight and deep wheelset for the Cervelo S5.

I only got them last week and got to fit them in the bike this. The box came damaged so I wouldnt go again with this shipping method. Luckily for me, wheels were undamaged.
I've only done two short rides with the wheels so too early to have any real conclusions on them. So far happy with them. They roll very well but time will tell I guess.

I might reach a biased crowd posting in this thread.
Do you rate Zen over XMCS nowadays? Are there any other players competing in price/performance?
-
FWIW I now have 2 sets of XCMS wheels. The 50’s and the 35’s for mountain climbing. I don’t have Zen wheels but am more than happy with the quality, ride feel and weight of the wheels. The 35’s are 1050g. Also have their cranks which are no logo gorgeous.

Not really—I’ve got wheels from both Zen and XMCS, and they each have something to offer depending on what you're after?
XM CarbonSpeed stands out because they invest heavily in developing their own products. That includes not just rims, but also frames, bars, cranks, and even their own hubs, which gives them more control over quality and performance.
There are loads of OEMs in Xiamen—up to 50 active manufacturers maybe more but not all of them are at the same level. I’ve been speaking to another one recently, and while they do manufacture their own rims, they still buy in spokes and hubs, so it’s not as advanced or cohesive as what XMCS offers.
-
Do they have a website or a contact point? I am looking for 650c wheels.

I would love to try a set of 40/45 wheels.
Unfortunately the closest place to get decent climbing is a 2 hour drive from Chicago. Lots of rolling hills. 1600m of climbing for every 100km of riding. Nothing sustained longer than 3-4 minutes however. Maybe I'll fly out to California this winter.

Hi guys, I'm new to the forums. I want this post to serve as an introduction: I'm Daniel and read the forums mostly to learn about more straightforward cycling products made in China. I grew kind of bored of the marketing especially for road bikes, so here I am, looking for a new frame on which to build an all rounder road bike.
On another note, I respect your relationship with the brand and people behind it, but don't you think a sub-1000 gram wheelset can be worryingly light?

That's why rider weight limit exist

No, I don’t think a 1000g wheelset is worryingly light at all — there are wheelsets out there that come in at 650–750g, so it’s not unheard of. When I made my decision, I did put some thought into it. I’m around 75kg on a good day, and if you’ve read the thread, you’ll know my front wheel has a 90kg rider weight limit. So I went ultralight on the front.
For the rear, I could’ve gone with a 90kg limit too, but I chose a wheel rated for 100–110kg to give myself a bit more margin. That’s in line with other respected brands like CRW (Craft Racing Works), which also have 100kg rider limits — and I’ve used those wheels before without any issues.
Yes, in hand they feel light, but if you’re going to ride a wheel with a 90kg rider limit, you just need to be mindful of how and where you’re using it., I’ve also got another set of 60/65 mm wheels with a 90kg rider limit that weigh around 1230g, and I’ve been riding them for months with no problems and I'm in the UK where we are not exactly know for our smooth roads ;D
So if you're someone considering going down the ultralight route with 90kg rider weight limit wheels, you really need to think about how you're going to use them. Personally, I wouldn’t use a wheel with that limit for anything other than road riding. I know some people use them on gravel, and some are even sold as gravel-capable — but if I were going to run a 90kg limit wheel on gravel, I’d want to be around 65kg myself.
If you're looking for something super lightweight but still robust, brands like XM CarbonSpeed are worth checking out. They use T1100 carbon in their lightweight wheels, which is rare — most brands stick to T1000. And despite being lightweight, many of XM’s wheels have a 120kg rider weight limit, which says a lot about their engineering.
So yeah, it really depends on the brand, the materials used, and how well the wheels are designed. Just make sure the specs match your riding style and weight.

Good Idea give yourself some climbing legs ;D ;D

Thanks to this discussion, I've decided to contact Zara at Zen Carbon for information on an ultralight 40/45-depth wheelset.
In my area in Italy I ride about 1000 meters of elevation gain in 35 km distance so I'm looking for climbing wheels for my new SPCyle R088 and I think this choice is the most suitable for me.
I still have a big question: 21 or 24-depth internal rim?
I've always thought that wider wheels are better for heavier weights, I weigh 60kg, and I'm unsure what advantages I could get.
Currently, for my 60kg weight (plus 9kg of bike) with 25mm tires and a 21mm internal rim, I inflate to 69/74 PSI (4.8/5.1 bar), and I'm happy with it.
With the 24mm internal rim, I'm forced to fit a minimum 28m tire.
Sram's tire pressure calculator suggests that with 28mm tires and a 24mm internal rim, I should inflate to 46/60 PSI (3.9/4.1 bar).
Aside from looking like you have flat tires ;D what are the real benefits?
Sorry for the maybe a bit trivial questions but I'm still learning!

How good are your roads and do you feel like you could use some more comfort? Additionally how important is aero to you?

My limited knowledge tells me you will have a more comfortable ride. That will be the biggest take away.

Patrick, try out a 50/40 or 45/50 instead! I'll see you in NorCal!

How good are your roads and do you feel like you could use some more comfort? Additionally how important is aero to you?
Hi toxin,
I only ride asphalt, I don't race, and I don't ride dirt or gravel, I use a mountain bike for that! I don't use tubeless or latex, only on MTB ;D
The asphalt in my area is pretty good. There are a few potholes, but I'm not lying.
I'm currently riding 2021 Farsport Feder wheels with satisfaction, 21mm internal width and 30mm depth, with DT240 hubs, weighing ~1,250g.
And I'm not very aerodynamic by nature, I just wish I could get some wheels reliable as these are!
And also, I prefer 40/45mm max high because the wind scares me!
I might actually try fitting a 28mm GP5000 to my current rims and see how I get on, I've tried it in the past but without any major differences and if I don't like them I'll fit it to the wife's bike! ;D
One last thing, you confirm that putting 25mm tires on wheels with a 24mm internal channel is pure madness, right?
-
Well roads don't have to be ruined to be bad, a rough road surface and cracks can tilt the balance in favour of wider tyres pretty quickly, even if the surface looks pretty uniform otherwise.
The best thing you could do for aero stability is put an aero 111 tyre on the front wheel. Alternatively a wider rim with a rounded nose and a narrower tyre will help as well.
If you were looking for stability regardless of tyre choice, a rim with very wide hook bead like the attached picture will be the most effective, but because it's so wide, it'll be a bit heavier and aerodynamically slow. I believe Zen should have access to these since they seem to be getting a lot of their rims from the same places as others who offer the same designs.
-
Well I must be crazy with my 28mm tyres on 24 and 25mm internals ;D ;D
Zen don’t do ultralight in 21mm only superlight.
But definitely more comfortable with wider widths not doubt we will go full circle and we will be told it’s all wrong and narrow is better ;D
Still can get a respectable weight 45/50 with DT Swiss hubs and sapim spoke 1235g.
Get that DT have the rep but they are $$$ I’m likely to get a set of winter training wheels with steel spokes but will probably go with the Z180 hub zen have which is as Toxin said a Goldix hub half the cost of DT Swiss.

Dear All,
I have been lurking on the forum for a few months and have really appreciated the insights and reviews provided. I’m currently hesitating between Zen and XMCS for a set of wheels with CX rays. Zara has been very easy to communicate via Instagram. Currently looking at 45mm with 24 internals.
I have two questions that I haven’t found answers here or on WW:
1) How is the build quality of Zen (trueness, spoke tension, etc)?
2) Does anyone have any experience with the H Works SR261 hub? Seems almost too good to be true.
Thank you!
-
Hi all!
After having some glorious conversations with Sander, I took the plunge and ordered a set of Zen.
I went lightweight, 50/50 with a 5mm carbon spoke. Zara advised there is a tiny weight penalty for the hub colour but it’s by the by.
They took around 6 weeks to arrive but I wasn’t counting……lol
Anyway, they came yesterday.
Quality is great, packaging was very very nice. Came with spare spokes, tubeless tape and tubeless valves.
Weight is 1219g which I think is very respectable.
They run fine with the included 36t ratchet.
I did try putting in a 54t but for some reason the cassette won’t spin with them. The facial drag between the ratchets must be too high or the spring rate must be too much. So I put the 36t back in. It’s fine anyway. I was just looking to make them obnoxious.
I’m hoping to get out this week for a spin.
My only gripe is also that now seeing the gloss….i should have done that. But I’m now thinking…..another set?

) How is the build quality of Zen (trueness, spoke tension, etc)? I don't check spoke tension I just order my wheels and ride them never had an issue if your goanna check tension may as well just build your own wheels. Wheels are true not much more to say!
2) Does anyone have any experience with the H Works SR261 hub? Seems almost too good to be true. Yes two of my wheelset have H-Works GOOD quality hubs. SR261 too good to be true what do you mean?

Quick weight-weenie update on the Zenwheels: I picked these up initially as climbing wheels (40mm front, 45mm rear), but after a few rides, they’ve proven brilliant for blustery UK weather. Had gusts up to 25 mph today, and they handled really well.

Thanks so much for the quick explainer. If they work for you, they'll sure work for me as my max has been around 68 kg at 166 cm tall. My wife is the same weight but taller at 175 cm. I'm investigating parts for a two all-around builds for both of us, based on the Spcycle SP-R088.

That’s ok Ultralights wheels are great for certain senarios and uses but if your doing every day riding I would consider Superlight instead 100-110kg limits and the weight penalty is 80grams.
But if you live in a country with lovely smooth roads then great! Unfortunately I don’t 🤣 the UK is rough as f@ck 🤣

Just ordered a set of 45/45 winter wheels for here in the UK yesterday — posted in the Winter Trading Wheels thread because I wanted some feedback and ideas before deciding.
Specs:
• Front/Rear: 45mm
• Rim internal widths: Front 31mm / Rear 24mm
• Rear asymmetric: 32/25mm
• Spokes: Sapim CX-Ray
• Nipples: Brass
• Hubs: H-Works SR 318 Gravel — was going for Ti Grey but now opted for silver with TPI steel bearings (LBLU sealed)
• Finish: UD Paintfree Gloss
I also ordered a set of 40/45 climbing wheels to replace the ones I originally bought but sold yesterday to a guy who was desperate for climbing wheels — which actually works out well!
After seeing someone here with the UD Paintless Gloss finish, I got a bit of wheel envy 🤣, so I’m going with that finish too. And I’m also choosing silver hubs this time, rather than my usual black.U

Wanted to give an update on these wheels thus far.
Had them out for some short and a couple of longer rides (100km+).
Absolutely no complaints.
Stiff, responsive, minimal to no flex.
I've had them over 70kph and they are absolutely rock solid and stable.
I've also sprinted on them with some decent watts and again, fully stable.
I got PR's up the hills without even really putting in an effort which honestly surprised me too.
Gusty day at the weekend and didn't have any noticeable push from the sides.
All in all, really really impressed for the price.
Only thing I wish I had done was glossy.
But they still look great.
All I can do now is wait, ride them more and see how they go long term!

Update here today. Done now maybe 1k km with them and happy with them so far. Very light and stiff but not mad stiff.
However, something which I feel these wheels don't do great is crosswinds. They seem to catch it more than any other wheelset which I have ever ridden.
Hopefully bearings last! I'll put them away now for the winter as I don't think they could do great hete in Ireland :-)

Interesting! I have done maybe 500km on mine now and compared to my set of Hunt wheels (50mm as well) I find the Zen much better in the crosswind. Even with a wide carbon spoke.
Mind are also stiff but not to cause any discomfort. Its only having moved from the Hunts to the Zen that I now realise how much flex the old wheels had.
But mine have been rock solid so far. Really stable decending too.

Maybe it depends what someone compares the Zen against. I am comparing them to my Hypers and Rovale C50s.

Winter wheels update 🚴♂️
This week I was looking into titanium spokes and thought they might be worth potentially swapping onto my winter bike/training wheels. I contacted Zen to see if they offered them, and it turns out they do. Titanium spokes come with aluminium nipples by default, and I asked if they could do brass instead, but they said galvanic corrosion between brass and titanium wouldn’t be ideal.
Since I don’t always clean my bike immediately in winter, it didn’t seem worth the risk, so I’ve decided to stick with Sapim CX-Ray and brass nipples. Interestingly, talking to a few people, titanium spokes seem to be becoming more popular for gravel build

Just made and order from Zara through whatsapp and we finalized the specs yesterday and opted for a UD glossy 45/55mm, SR261,36T Rachet, ceramic bearings, sapim cxray spokes at 1340grams. This morning, I was surprised to receive a video of the finished wheelset (attached) and sent me a photo if i can received factory minor IMPERFECTIONS, as Zara politely offered and said.
So I was wondering from those who received their wheelsets and share its imperfections, tolerable and not, is appreciated.

These kinds of marks are typical of UD carbon layup, especially on paintless finishes where the raw carbon texture is exposed. Variations like this can result from:
Resin pooling or slight fiber overlap during layup (rims are layed up by hand)
Tooling marks from the mold
Natural texture differences in the carbon weave
They’re cosmetic and common on UD paintless rims, especially when no paint or clear coat is used to mask the surface. Unless there's a crack, delamination, or deep gouge (which this is not), these are not defects.
If you want perfect rims you ask for Black gloss.
I have this on my rims as well

Currently have the Elite-Wheels Marvel 50D wheels but eyeing for a new set of wheels. Probably saving for a set for next year, some questions I had:
1. For an all rounder wheelset, is 45F 55R good especially on some windy days?
2. I know that there are 3 carbon versions, I weigh 185lbs which version would be recommended?
3. How many spokes, and what width?
4. I have seen some pictures of some wheels and was tending towards the no paint look but then saw the glossy one. Are there any pictures that compare the look side by side?

1) I can handle 50mm on the front on windy days fine. 45 should be significantly better. the rear doesnt matter much, so 55 is fine. I run 65 on the rear and don't notice much difference.
3) I run 16/18 on a set from XMCS and weigh around the same as you do. Peter said I was plenty light enough for 16/18, and I've been throwing myself down rough roads to put together a proper review, and they're fine. Broke my bike computer mount on a crack in the road, and the wheels held up fine. If you want a super stiff bike, you can get more spokes. Width doesn't really matter. Go narrow to save weight, or go wide for aesthetics

3. I know XMCS do have a different weight limits and they were also on my radar, will keep that in mind regarding the 16/18!

Why do you like the 16/18 spokes versus 20 or 24? Weight, crosswinds?

Aero benefits, slightly more flex on the front inspires more confidence in sprints and descents, haven’t’ noticed any difference in the crosswinds

Just got my wheelset delivered this morning. Packaging was great. I've only had time to unbox the wheels, weigh them, and snap a couple of photos.
Specs:
- Rim depth: 45mm front & rear
- Rim type: Hooked, tubeless ready, with a drain hole on one side
- Rim width internal: 24 mm
- Rim width external - at the top of the rim: 31 mm
- Rim width external - at the widest point: 34 mm
- Rim finish: UD satin
- Rim build: Ultra light weight front & rear (90 kg system limit)
- Hubs: ZSL230, 36T ratchet, 20 holes front & rear, ceramic bearings (claimed weight 228 g)
- Freehub: HG 11/12s Road (I also ordered an XDR freehub)
- Spokes: Carbon, 3.1mm width (claimed weight 2.1 g each)
Inclusions:
- Four spare spokes with nipples (one for each length used)
- Tubeless valves
- Tubeless tape - I asked for it to be preinstalled, which they did
And finally, the weights - which includes the tubeless rim tape:
- Front: 493 g
- Rear: 576 g
- Total: 1069 g
-
That’s One light set of wheels!

This was the spec I asked for:
F Rim
d55,iw24 Lightweight
F Rim (g) 460
F Hub HX240
F Hub (g) 71
F Spokes
CS04 5.1*0.9 3.5g

R Rim

R Rim (g) 400
R Hub HX240
R Hub (g) 155
R Spokes
CS04 5.1*0.9 3.5g
R Spokes (g) 70
Estimated weight 1226
(I think I estimated the independent front and rear hub weights but can't remember how...)
The cs05 spokes don't fit otherwise I'd have gone for those.
Hubs are beautifully finished but I'd have taken the tiny weight gain over what are now almost vestigial splines on the disc and cassette. Going to pull the front rotor fairly regularly I think as they honestly look like they've gone too far.
Actual weight on a Kern balance 1213g. Look great in the sun - poor indoor lighting in the photos.
Pretty standard build quality tension wise. That said I'm an inveterate spoke plucker and I've never been impressed with any pre built wheels yet. Contrary to popular belief carbon spokes are incredibly easy to build with compared to superlight steel and/or shallow rims.
I built a set of Speeder rims on Aerolites that now have 25k of abject abuse on country lanes and are straight as a die. I'm 72kg. Those were the heaviest of the four tiers (i.e. normal) so I've just gone one lighter.
The new ones definitely have a decent amount less carbon in the walls as they're noticeably tinnier to tap and give to gentle pressure.
I'm not sure if anyone has pointed this out but the rims are plainly Speeder/Adapt. Diagrams and weights match exactly.
I also had a pair of the Speeder 45 carbon spokes wheels but the token hubs are pretty heavy and they don't offer any variations of their carbon spoked wheels.
-
If the disc lockrings are torqued properly, the splines aren't what's carrying most of the load

(I think I estimated the independent front and rear hub weights but can't remember how...)
The cs05 spokes don't fit otherwise I'd have gone for those.
Hubs are beautifully finished but I'd have taken the tiny weight gain over what are now almost vestigial splines on the disc and cassette. Going to pull the front rotor fairly regularly I think as they honestly look like they've gone too far.
Actual weight on a Kern balance 1213g. Look great in the sun - poor indoor lighting in the photos.
Pretty standard build quality tension wise. That said I'm an inveterate spoke plucker and I've never been impressed with any pre built wheels yet. Contrary to popular belief carbon spokes are incredibly easy to build with compared to superlight steel and/or shallow rims.
I built a set of Speeder rims on Aerolites that now have 25k of abject abuse on country lanes and are straight as a die. I'm 72kg. Those were the heaviest of the four tiers (i.e. normal) so I've just gone one lighter.
The new ones definitely have a decent amount less carbon in the walls as they're noticeably tinnier to tap and give to gentle pressure.
I'm not sure if anyone has pointed this out but the rims are plainly Speeder/Adapt. Diagrams and weights match exactly.
I also had a pair of the Speeder 45 carbon spokes wheels but the token hubs are pretty heavy and they don't offer any variations of their carbon spoked wheels.
They look good the weave looks good
It’s possible they may not manufacture the rims themselves. I spoke with Zara about sourcing 25mm inner width rims, the same profile used on the 8Lien and CRW. The factory produces them and conducts tests, but Zen will carry out their own testing before offering them for sale.
I also asked whether they make their own rims. Some they do, and some they don’t. As with many OEMs, not all products are made in-house; factories often collaborate, as many of us know.

Can you share a link to Speeder/Adapt for these rims/wheels? I have tried to find and am not having any luck. Thanks.

Per my previous message I'm as satisfied as I can be that these Speeder filament wound rims are top-notch and very durable at their standard weights. I've built a pair with Aerolites and a pair with carbon spokes and by far the easiest and most evenly tensioned result I've achieved.

Peter from XMC Made a comment on a FB post said these rims are coming from his friends factory.
Might be good to find out the actual source factory 🤔

That's right. I received quotation for the exact same rim from Zen and from Xiamen Most Sport.

I wonder if anyone other than Speeder/Adapt are filament winding. None of the factory tour videos I've seen showing rim manufacture have featured filament winding.

Good morning,
Sorry for my question, but I have been following this topic with great enthusiasm and I would like to thank everyone who is contributing with new information almost every day.
This wheel rim with the butterfly effect (it looks a lot like the Lun wheels) — is it also offered by Zen? If so, is it just a type of final finish or do they have a unique list of models, sizes, and weights?
I’m looking to place an order with them for wheels and the crank arm.
Best regards,
-
A second question: do you know if they can apply a brand’s graphics on the rims? I saw the stickers with their own brand, but would it be possible to customize them?
I work at a bicycle factory here in Italy, and after buying and testing for myself, it wouldn’t be a bad idea to see if there would be interest here in purchasing their wheels on a slightly larger scale.
-
Wouldn't be easier to ask directly? Butterfly effect is just a type of finish. As an OEM they can put any logo you want for the additional price for sure.

Yes
They offer Multiple Rim Finishes including the butterfly weave Zara has confirmed that this is the carbon layup she has confirmed the can also do custom logo/decals
They have a list of rim profiles and sizes with weights and different KG load limitations

Yes, certainly! But since I had just finished reading all 11 pages of the topic and was excited about everything I read, I ended up asking the question here first (of course, I will contact them directly). ;D

Thank you for the response! So I’ll use as reference the images that have already been shared here of the model, weights, widths, etc… this way I can start contacting Zara with something more concrete!
Thanks to everyone for the answers.

Which wheels do you believe have a butterfly effect solely as a cosmetic layer? I can't imagine how/why a munfacturer would choose such a hybrid lay-up but happy to be corrected.
If you look at (every) other wheel on this thread you'll see they're also filament wound but with a narrower tow and (obviously) a final constant-angle outer layer. I have one set on of Speeders like this and another with butterfly. And now a second set of Zen with butterfly.

Butterfly pattern is also made from the UD carbon fiber cloth, just layered differently in the form. It's the same with other fancy finnishes as "forged carbon", marble effect and others 'XX' Ks used for ascetics.
-
Marbled/forged are just a random mess of fibres, but i don't see how you create a butterfly effect which is a very accurate radially aligned pattern. No two arced sections would be the same and joint would be super obvious.
I have a trashed butterfly film and the outer surface is clearly following the same layup as the inner layers. I'll take some photos at the w/e.

The problem you're going to have is that there is simply nobody developing things for rim brakes anymore bevause the market is for it is too dead to be worth it.

Well, you may or may not have seen it, but there’s a lot going on over on Weight Weenies about the new 9Velo wheels. They’ve just released what looks to be the first sub-1000 g 50 mm wheelset — technically 52/52 mm at a claimed 999 g.
Everyone jumped on them because the advertised load limit was listed as 110 kg, but that’s now been quietly revised down to 100 kg some pissed people.
Then someone pointed out that BTLOS have what appears to be the same rims, originally claiming a 120 kg limit — but when checked, they also confirmed 100 kg.
https://www.9velo.com/products/9velo-2026-ultralight-road-disc-carbon-spoke-extreme-c52-road-wheels-20h-20h-236-mm-inner-wide,-sub1000-grams?VariantsId=11772
You really have to watch these bold claims around rim load ratings now. The rims clearly have certain criteria for use — looks like they might be better hung on a wall and posted on Instagram rather than actually ridden! 😂
I emailed Zara at Zen the week before last when I first saw them. She confirmed they should be getting those rims — total weight would come to around 990 g (two 340 g rims, 226 g hubs, and 84 g of spokes). She initially said 100 kg, then later told someone else 90 kg. Hopefully, I’ll get more clarity from her tomorrow — I’m still potentially looking at getting a set myself.
Hi Stephen,
High power means:
· Heavier riders: For example, cyclists weighing over 85 kilograms.
· Sprinters: Riders with extremely powerful bursts, capable of generating peak power outputs easily exceeding 1500W or even 2000W during out-of-the-saddle sprints.
· Power riders: Cyclists who can produce massive torque even at low cadences.

Hey h0ldb88r
Zen can now offer carbon rims without holes in the rim bed for carbon spokes. However, these wheels are more difficult and time-consuming to build, so there’s an additional cost of $50 USD.
I’m not sure how much weight this design adds, or whether it’s only possible with certain rim models — I’d need to check with Zara on that.
The first photo shows how the spokes look when laced on a rim without spoke holes — personally, I’m not a big fan of this look.
The second photo shows a rim with holes in the bed, which I prefer, especially since I’d rather use rim tape if I were running tubeless.
-
Agreed. That second photo looks a lot better. The first photo doesn't have the streamlined look of internal nipples, and I'd rather use tape in that case.
-

100%
You considering pulling the trigger then?
-
Yes! Thanks for all your work for the community to explore these options.
-
I think it’s impossible to have a rim without internal holes and internal nipples, because somehow you need to have access to the nipples in order to adjust the spoke tension.
One detail I’ve noticed here while working in a bicycle factory is that a wheel with internal nipples must have small side holes for water drainage, since the internal nipple design allows a lot of water to get inside the rim, and without those holes the water cannot escape.
-
All rims should have that. Not just to evacuate water, but if there's a failure at the valve or rim tape and air escapes into the cavity, it could pressurise it so much it explodes.
-

You should let ENVE know about this. The number of wheels I receive here at work (we sell ENVE wheels) for warranty because they exploded is huge! :o

Yeah it sucks, I've heard that their supply of HX hubs got cut off and they might be forced to raise prices.

Yes potentially
The HX hub is used in a lot of premium and high end wheelsets
They may have to Tier there wheelsets we will see
Disappointing not good for the small buisness pretty much getting strong armed buy the big boys basically.
There are other hubs out there so somethings is likely to crop up that will likely compete with that hub anyway.

Hi!
Very nice set of wheels!! Just one question: with this finish glossy, do you think it's similar to a Campagnolo wheel? Like the bora wto.. I'm asking because I have this wheel here in my job, and if it's a similar finish, I can have a better idea of how is this glossy finish...
Thanks in advance!

I’m not too sure, Maliba . This is obviously the UD paint-free glossy version, so it’s a gloss finish over raw carbon.
I do get messages and comments sometimes about imperfections, but if you go for the matte version, it’s not really noticeable.
Putting gloss over the carbon just highlights its raw nature. Occasionally, you can see the resin under the carbon, especially in certain lighting.
If you want something that looks much more “perfect,” it’s better to go for a black gloss, where they apply a matte black over the rim first and then the gloss on top.
You’d have to send me a picture if you want me to show exactly what it looks like.
-
Anyway

Ngl that silver hub looks sick! Would love a pair of these.

Thanks, I think it's quite similar to Campagnolo!!

I had a proper ride on them today. A couple of Lakeland passes in mixed weather and I'm very happy. They seem to roll well, cope well with the wind, and are very comfortable. With the amount of standing water about I should fine out pretty quickly if the sealing is up to standard.

Hi,
yesterday I purchased a pair of wheels from Zen using the same specs that Sander posted here—basically 40/45 mm depth with 24 mm internal front, 25 mm internal rear asymmetric, with carbon spokes in back, etc. I also ordered the crankset, so now it’s just a matter of waiting for the parts to arrive.
One question: I use Shimano on my bike—do you recommend any spider to allow mounting Ultegra chainrings on the crankset?
Thanks in advance.

That spider looks like the one from DFS, if I’m not mistaken. I was checking out a few on AliExpress, which I believe are made of aluminum since they weigh a bit more. I also saw one from Elilee (or something like that) that has a perfect finish with the Shimano chainrings — but it costs a fortune! lol

They are generic. If you do a search on AliExpress thats a photo search a load will come up.

That’s what I’ve been struggling with Elilee seem to be the only brand/seller who seem to do one that is contoured perfectly to match Shimano chainrings. I’ve been looking everywhere for a generic DuraAce model
-
Might be a dumb question here—but struggled to look for an answer to this question...
Is it at all possible to use lets say the Zen Carbon crank (or similar cranks offered by Elilee, XMC etc) with a Magene PES P515 PM spider only by simply not using the crank that comes with that kit?
I like the idea of running a Magene PM but not so much the aluminium crank that comes with it.
Otherwise, I may have to go down the route of an XCadey PM or similar.

The Magene PES P515 uses its own proprietary spider mounting interface - it's not compatible with any others.

-
Yes, they are compatible. I was meaning that the Elilee ones are the only ones on AliExpress that have the surface contoured to exactly match the Dura ace chainrings. The generic ones seem to have the 4 ‘splines’ not built up as far so that a ridge would show. It’s purely aesthetics though, not performance related.
-
I initially bought this wheelset for my upcoming road bike, but then a gravel bike with heavy 650b wheels arrived in my fleet. So I gave the gravel bike a very nice-looking upgrade. (Zen Carbon 60/55mm 3.1mm carbon spokes, SR270 hub, +-1300gr)
Yesterday I came back from a ride and noticed that many spokes on the non-drive side are twisted. Some even up to 90 degrees. Front wheel is perfectly straight, rear drive side as well.
I can't think of a reason why this would happen during the ride, so I assume they already came like this out of the box.
Either way, they need to be straight again. I got this full-aero wheelset and the spokes are literally catching the wind now.
This is my first carbon-spoke wheelset, so I'm hoping to get some advice on the best way to fix this. I tried loosening a nipple to release tension so I could straighten the spoke, but the spoke itself rotated. Before I grab pliers or something to hold it in place, I thought I'd better ask here first.
Friendly experts from Chiner, please advise! 😄

Carbon spoke nipples are tightened differently than steel ones. You need to take the tire and rim tape off and insert a tool from the access holes to the nipple. Get the correct tools and research how it works. Do not try to stop the twisting by holding the spoke. I would contact Zen about the problem.
-
https://youtu.be/UVzACwu9-YM
If you've twisted the spoke too much, there's a non-zero chance you've already damaged it.

Would also be interested in how ZEN deals with this case as I am about to order a wheelset.

Grab both metal ends of the spoke with something and twist at the same time.

I initially bought this wheelset for my upcoming road bike, but then a gravel bike with heavy 650b wheels arrived in my fleet. So I gave the gravel bike a very nice-looking upgrade. (Zen Carbon 60/55mm 3.1mm carbon spokes, SR270 hub, +-1300gr)
Yesterday I came back from a ride and noticed that many spokes on the non-drive side are twisted. Some even up to 90 degrees. Front wheel is perfectly straight, rear drive side as well.
I can't think of a reason why this would happen during the ride, so I assume they already came like this out of the box.
Either way, they need to be straight again. I got this full-aero wheelset and the spokes are literally catching the wind now.
This is my first carbon-spoke wheelset, so I'm hoping to get some advice on the best way to fix this. I tried loosening a nipple to release tension so I could straighten the spoke, but the spoke itself rotated. Before I grab pliers or something to hold it in place, I thought I'd better ask here first.
Friendly experts from Chiner, please advise! 😄
Wheels do settle — it’s normal for new wheels, especially if they haven’t been ridden yet. I’d personally get a local wheel builder or local bike shop to give a cost to check and sort them out first. Once you know that, then contact Zen and let them know: this is the issue, and this is how much it will cost to get the wheels checked over, and see if they cover it I would not touch the spokes myself.

My ZEN wheels arrived with a damaged spoke, which I had to replace myself. Apparently, ZEN doesn't take quality seriously ::)
Next time I certainly won't buy anything from ZEN and will instead ask Peter from XM Carbonspeed or buy reputable brands with character.

Can anyone share the spoke tensions needed? Here is my order:

Zara told me 110-120kgf when I asked her about it. This was for the rear though. Not sure of recommendation for the front is the same.

Wheel has been checked by the bike shop. Replaced one spoke and straightened and tightened the rest. €30.
I shared the case with Zara and asked her how we could solve it.
ZEN will cover the cost.
Nothing but compliments about the way that they've handled this.

Hi friends :)
I am close to ordering a wheelset from ZEN. However I am still a bit unsure which profile to go for. I am torn between the 24 iW / 31 outer and the new 25 iW / 32 outer.
I already am pretty much set for:
- 60/60mm depth
- 3,1 ultralight carbon spokes (dont like the looks of the 5,1mm)
- steel bearings
- 54t hub
I am at 85kg bodyweight (coming from Crossfit and weightlifting). The bike (about to order an X68 frameset) will be used almost exclusively in the flats.
Any advice on rim width etc. is welcome!
-
I think the wide the better. But also take note of what tires you will use. 25 IW will be better if you'll use 30c or above.

I would not buy Ultralights at 85Kgs the load limit of these wheels is 90kg that includes bike and luggage, that said I would not buy them at my current weight or even whem I am at 74/75kgs.
They are not a suitable rim for everyday riding plus the UK roads are dog sh1t
I'm 77kgs and go with Superlight Rims 100-110kg more suitable for everyday riding you should, have maybe a 10-15kg margin from your total load to the wheels load limit .
I dont think you will see much difference in profile in 1mm
-
Thanks for the replys so far. I was aiming to go for ~110kg load limit. As the 24iW superlight rim has a lower weight limit I would go superlight front and light back. For the 25 iW the superlight limit is 120kg so I should be fine.
I don't plan to go any wider than 30-32 WAM for the wheels. For anything streets/terrain requiring more comfort I have a fast gravel bike.

Yeah, super light—25 mm sounds good, with a 120 kg limit probably better since they’re very light. The 24 mm internal width rims are specified as 100–110 kg, which is pretty similar to what I’m getting from Serenade Wheels. The wheels I’m getting are rated for a 110 kg rider. Their rims measure 34 mm external at the widest point, with an internal width of 23 mm—should be interesting to see how that compares when I get them.
On their website, the listed wheelset weight is 1,280 g, but if you add up all the components, it actually comes to 1,326 g—so the info is a bit contradictory. If you go to the link, the spokes are listed as 3.3 mm or 3.5 mm, and the photo shows something slightly different, so again, there’s some contradictory information. Those are obviously bladed carbon and steel spokes. The upgraded ones I’m getting are 2.9 mm bladed carbon–titanium spokes, which should enable the wheels to actually hit the advertised weight listed on their site.
There were some hiccups with my order initially. I actually got photos of the Serenade wheels last week, but they sent just a glossy finish instead of the UD Paintless Glossy I originally requested. It’s not a big deal since it wasn’t urgent, but to save time, I’ve decided to go for the UD Painfree Matte finish this time. Hopefully, the wheels will be sent out next week. I’ve asked them to send some photos before shipping, just to make sure I’m happy, so we’ll see how it goes.
-
That 23 IW with 34 EW is pretty interesting. I removed serenade from my choices because their 24mm iw is v-shape (I want to try U-shape) but it seems that they have another interesting choice. I would talk to them again for more information. Meanwhile, I really wanted to get DFS wheels because of their R2 hubs!
-
The people with quality issues, have you heard any feedback from Zen? Interested to see how they handled it.
-
Just want you guys to know that Zen is also offering r2 hubs! Very interesting, i am now leaning towards buying Zen because of compelling rim profiles

Do you have this kind of profile but 24mm iw?
This particular profile no. We have numerous rim profiles available.
We have 24mm Inner but this is a U Shaped Profile. We have 25mm Inner width which is a similar profile. These Profiles are however Wider externally and not as light.
Please contact me for mor information on Whatsapp

@ZenCarbonBike, since your website isn't up to date, it'd be helpful to post your rim profiles here for members to see along with weights of rims. Spoke options and also hub options.
I'm interested in either 24 or 25mm internal, 40 or 45mm deep, along with carbon spokes and also the THR industries R2 or R3 hubs.
-
@velothree just send Zara a WhatsApp, I’m sure she’ll send you the details through
-
I thought i give my thoughts on them.
I had order my wheel just a day before their golden week .. Zara team work around the clock to get my order up as i was due to fly overseas to cycle.. and they did.. but i had to postpone my trip due to the typhoon hitting Taiwan.. but i have been putting some serious mileage on them and they are holding up pretty well. Mine is the version before the ultra light weight version.. its about 1017 grams.
fast forward to 2 month later and i had the opportunity to visit their factory and of cos their cold storage where they kept their prize Toray material. We spend some time discussing about Zen Wheel future development and i would say it definitely worth giving them a try. they are much smaller scale compare to some of the others factories so the range of rim SKU might be not exhaustive but whatever they have right now should cater to our needs and the attention to details and quality is decent.. to give you some context, i had been using light bicycle since 2012 and farsport wheel for a long time and working with Zen....i would say they just as good.

Good Day Chinertown Forum Members,
I hope everyone is well.
Following my post from 27th November, I’m pleased to share an update on our new Zen VaporLite Extreme Ultralight Rim.
We now have the first production sample of the 50 mm VaporLite rim.

• Estimated weight: 330 g
• Actual production weight: 326.6 g
(Production photo link attached)
https://ibb.co/2YYy1J3N

Lead Time Update – Effective 8 January
Starting 8 January, our standard production lead time will be 4–5 weeks.
Please note:
If the estimated shipping date overlaps with the Chinese New Year holiday (14–23 February), an additional 10 days may be required due to reduced factory capacity, as many factories shut down or operate at reduced capacity during this period.
We cannot guarantee that any orders placed from 8 January will ship before 14 February.
We’ll provide a fresh timing update once operations resume after the holiday.
Many thanks for your understanding.

Decided to try out the new VaporLite Ultra wheels, 50mm 984g. Zara was very responsive and answered all the technical questions I had. Got the order in yesterday, 14.01, so expecting to receive them in Feb-March.
At the moment I have different Go-Zone carbon spoked wheels on road bikes and Elite Gravel Aero+ on my gravelbike. All been perfect and no issues with them. Just interested to see how much difference there is between 1200g and sub-1kg wheels, if any.

Good Day Sir,
Answer to your question:
28 mm Ideal Best balance of shape, support, rolling resistance, and aero.
30–32 mm Very good More comfort and grip; still perfectly matched to 24 mm internal.

Do you offer coloured/anodised hubs?

Do you offer coloured/anodised hubs?
Good day, Sir,
Unfortunately, we are not able to offer this. Our hubs are generally available only in black or silver. As we do not manufacture our own hubs, producing a specific colour would require a minimum order of around 50 units.
I’m sorry that we cannot assist on this occasion.

25 internal vaporlight should be a good match for 32-35s , I think?
Wider is just more weight.

I can also recommend the ZEN 25mm internal. I want to use it for my winter/commuter bike, so as an all-rounder. Currently winter tires with 32mm – planning something a little faster for summer, up to 35mm. I also find the new Vapor very interesting; you can definitely build a great setup with it.
I was inspired by Sander2177—thank you! And the contact with Zara from ZEN was great. I am satisfied with the result.

i don't really care about weight, I want aero and comfort. I already have a light wheel set. 29 internal with 35 or so external will pair really well with 32s.

Good Day
Is this for road?
We have a 50mm depth with 25mm internal width 32mm external at the bead and 34mm at the rim.
However if you are looking for something wider we have available rim options to suit with multiple rim weight options if weight is not a concern

After selling a couple of wheelsets, I ordered another set of Zen wheels the week before last for my upcoming Quick Pro build:
65/65mm rims, 25mm internal width, paired with the R2 hub in silver and 3.95mm spokes.
Now that Zen can source THR hubs, I initially ordered the THR RX hub. However, I was fortunate to cancel it in time. The carbon spokes I was considering weren’t suitable for the setup, and the RX hub can’t accept anything wider than a 2.3mm spoke. The more appropriate spoke options were heavier, which ultimately defeated the purpose in terms of both weight and cost.
As a result, I reverted to the R2 hub with 3.95mm spokes.
I’m still considering switching to 3.1mm spokes for a slight weight saving, and I’m also exploring whether there’s a lighter, more suitable option available elsewhere — perhaps something in the middle ground around 3.4mm–3.5mm.
Estimated wheelset weight is 1292.5g.
There are lighter 395g rim options available with a 90kg load limit, but I’ve opted for the 425g version rated at 100–110kg for added strength and durability. The lighter rims would bring the total weight down to around 1232.5g. I could also have selected ultra-light 230g traditionally laced hubs, which would reduce the wheelset to 1177.5g, and with 3.1mm spokes potentially as low as 1104g.
That said, while I appreciate weight savings, I prioritise performance and reliability. What I’ve chosen represents a sensible balance between weight, strength, and real-world performance.

This is for road but bumpy road. I will run 32-35mm tires on this. I think the last rim will work. I will reach out

Vaporlite Ultra 50's arrived (ordered 14.01). Actual weight 991g so well within the margin (XDR freehub). Shaving another 10g with titanium ratchets I'll be trying out in coming season.
Visually high quality as expected. Hubs are really looking nice and has a rubber seal between hub and freehub body, ratchet system uses just one spring. TPI bearings rolling smooth.
Can only be picky about the stickers. One letter was loose, many have sharper ends loose and not sticking back, which means I'll probably have to remove them after some use. Unless I find a way to make them stick. Not really an issue as they are just stickers. Overall very happy with the wheels. Have to wait for the snow/ice to melt to try them out. Pirelli PZero 28/30mm will be mounted on them soon.

I use them on my gravel and road bike, they are fine. Installing an xcadey powermeter was a hassle cuz the fit was really tight. Now running it with directmount chainring and that went on perfeclty fine.

Hi all,
We’re considering to develop a new 50mm carbon road rim and would really value some feedback from forum members
Concept Direction:
• 50mm depth
• Modern U-shaped aero profile
• 25mm internal
• ~32mm bead / ~34mm max external
• 20 front / 20 rear
• Lightweight performance-focused rim
Rather than chasing extreme gravel-style numbers, we’re trying to optimise:
• Efficient U-shaped aero profile
• Lower overall rim weight
• Improved system load tolerance
• Better impact resistance than typical ultra-light race rims
• Compatibility with 28–32mm tyres (optimised around 30mm)
Spoke holes would likely be drilled with internal reinforcement for flexibility across hub types.
⸻
Open Questions:
1. Is 25mm internal still the right direction for 2026 road use?
2. Is ~34mm max width ideal for modern 30mm tyre setups?
3. Would you prioritise lower weight or higher load/impact margin?
4. 20/20 rear — acceptable for modern road builds?
5. Any concerns with U-shape profiles at this width and depth?
Looking for constructive technical feedback rather than brand comparisons.
Appreciate any thoughts.

I agree with the internal reinforcement for spoke holes for reliability reasons, but how does that help with flexibility across hub types?
My feedback to your questions:
1. Is 25mm internal still the right direction for 2026 road use?
Yes, I believe so. It relates to your second question. The combination of 25mm internal and 30mm tire width forms a round tyre profile, which improves predictable roll-over when leaning the bike from side to side. If you'd stuck a 25mm tire on 25mm internal width the profile is more flat which doesn't help with steering. Bigger internal width for road use does IMHO not bring any benefit.
2. Is ~34mm max width ideal for modern 30mm tyre setups?
Yes, that's perfect. 25mm internal width and a 30mm tire will sit nicely within 34mm external, making it aerodynamically a good match. I also believe that 30mm is the perfect width for fast road riding on most "typical" road surfaces. Bigger is only useful when the roads gets really rough.
3. Would you prioritise lower weight or higher load/impact margin?
Balance is key. Personally, I don’t see much real-world benefit in sub-1000 g wheelsets. At ~85 kg rider weight, confidence in strength and impact resistance matters more to me. If a wheelset comes in around 1100–1200 g with solid durability margins, that’s an excellent compromise.
4. 20/20 rear — acceptable for modern road builds?
Yes, provided lateral stiffness is sufficient. If the wheel can handle >1500 W sprint loads without feeling flexible, I’m comfortable with 20/20. Some degree of vertical compliance is desirable so the ride doesn’t feel harsh, but I realise that aspect is more subjective.
5. Any concerns with U-shape profiles at this width and depth?
No. U-shaped profiles at these dimensions are well proven aerodynamically and structurally, so I don’t have any concerns.

1. I would say 25-26mm is perfect for road 2026..
2. i would like even wider rims, to be better for 32-35mm tires. The trend is wider, so wider OW is better. XMCS does have 26/33 wider wheels,and i would even liken even wider, maybe 34-35mm..
3. Lighter is always better, but not at cost of lateral stiffness or TO LOW impact resistance.. myself i would not buy wheels with specified load BELOW 110kg.
4.20/20 is perfect.. doesn't give much lower weight going down to 18 or even 16 spokes..
5. I think going more in the vein of DT-swiss profile is better when going for wider rims.. maybe 33mm around the tire bead, then going up to around 36 at it widest.

Thank you, members.
Wider rims are definitely becoming more popular, but once we move beyond 25–26 mm internal we begin to overlap with gravel‑rim territory. There still needs to be a clear distinction between a modern road rim and a gravel rim in terms of width, structure and intended load range.
Lower spoke counts are also quite limiting. They reduce lateral stiffness and increase the load carried by each individual spoke, which raises stress at the nipple bed. This is especially true for lightweight rims where the rim bed and sidewalls are already optimised for weight. For a product to be suitable for a broad range of riders, spoke count and structural margins cannot be pushed too far.
Our goal is to create a rim with wide market appeal—balanced weight, stiffness, load capacity and compatibility—rather than something that only works for a very small group of ultra‑lightweight builds.

Thanks for the opportunity to provide some feedback as a non customer.
1. Is 25mm internal still the right direction for 2026 road use? This is perfect for me. I think any wider and 30mm tires become non-conforming by the standards. This is both a potential liability issue for the future as well as a safety one as tire bead shapes, materials, etc still seem to be changing. If you are looking to sell to racers, you should consider going down to 24mm or even 23mm to conform to standards for 28mm or 29mm tires as a lot of people race with TT tires.
2. Is ~34mm max width ideal for modern 30mm tyre setups? Maybe? At 50mm depth, it might be too wide depending on your design. I would like to see a wider, more U-shaped front and a UV hybrid rear. The profile of the front should be more friendly to wider yaws and the rear more friendly to shallower ones. I know this means two rim molds, but I also think from a marketing perspective, a matched set would be more attractive. There are three reasons to do this. First, you want the rear to be more aero than the front to move the center of pressure away from the steering axis to the extent that it matters, as it can help with crosswind performance. Second, your front wheel needs to perform in wider yaw conditions. Third, your rear wheel is marginal in the greater scheme of the bike but is relevant in cross-tailwind conditions where the draft effect is reduced. It is also the place where most riders are likely to get dropped, so a race-oriented wheelset should account for this kind of scenario.
3. Would you prioritize lower weight or higher load/impact margin? Even at 56-60kg, a design that prioritizes retaining margin comparable to the brands used for racing at the higher levels is preferred. I regularly ride with groups that average 38-40km/h and will go 50km/h+ on flat sections. I don't race much on the road. I am too old and too small to want to deal with folks wanting to shoot non-existent gaps at those speeds, but I still do competitive fondos and the like, and usually get past 90km/h on the descents. I have not had this discussion with you as a customer yet, but many rim companies recommend their heavier T800 layups to me over T1000 or T1100 once I bring up this use. If you could design a lighter rim that fits this use case without reducing the margins, that would be ideal.
4. 20/20 rear — acceptable for modern road builds? I am not qualified to answer this question in a technical sense with the information provided. I think it depends on wheel stiffness and the ability to absorb impact. I think 20/20 seems nice, for a wheel that's for like cafe rides and stuff, sure that sounds modern enough. But I wouldn't trust a wheel that I am not sure would hold up as well as I expect to hitting a pothole or road debris.
5. Any concerns with U-shape profiles at this width and depth? See answer to #2
-
1. Is 25mm internal still the right direction for 2026 road use?
Yes, 25mm internal is perfect. It’s now clearly established that 30mm tires are becoming the standard, and many riders are already using 32mm and even 34mm. So 25mm internal width aligns very well with where modern road setups are heading.
2. Is ~34mm max width ideal for modern 30mm tyre setups?
Yes, exactly. With wider tires becoming the norm, having an external rim width of 34–35mm will be important from an aerodynamic perspective. This supports the tire properly and optimizes airflow around a 30–32mm setup.
3. Would you prioritise lower weight or higher load/impact margin?
Weight — especially rotating mass — is always critical. If I were Zen, I would definitely aim for a wheelset under 1000g. From a marketing perspective alone, this would position you as a benchmark manufacturer at the cutting edge of development and production.
At the same time, as you are already doing, I would offer a reinforced version for heavier riders. That way you cover both performance-focused customers and those who prioritize durability.
4. 20/20 rear — acceptable for modern road builds?
Fewer spokes can also bring aerodynamic benefits. An 18-spoke option could even be interesting, simply because very few brands offer it — that could be a differentiator.
For me personally, it’s only relevant if it delivers measurable aerodynamic gains without significantly compromising stiffness or durability.
5. Any concerns with U-shape profiles at this width and depth?
For 2026, rim shape is probably the most critical factor. It must handle crosswinds very well — this is where the real differences between brands become clear. Stability and predictable handling in wind are absolutely key.
-
You can't eyeball a shape and expect it to perform. If you want to do it right, you need to spend time and money to at least refine it in cfd. You can make great or terrible rims with small or large nose radii, but you need to test and refine them, otherwise you're just gambling on getting luck.

Hi all,
We’re considering to develop a new 50mm carbon road rim and would really value some feedback from forum members
Concept Direction:
• 50mm depth
• Modern U-shaped aero profile
• 25mm internal
• ~32mm bead / ~34mm max external
• 20 front / 20 rear
• Lightweight performance-focused rim
Rather than chasing extreme gravel-style numbers, we’re trying to optimise:
• Efficient U-shaped aero profile
• Lower overall rim weight
• Improved system load tolerance
• Better impact resistance than typical ultra-light race rims
• Compatibility with 28–32mm tyres (optimised around 30mm)
Spoke holes would likely be drilled with internal reinforcement for flexibility across hub types.
⸻
Open Questions:
1. Is 25mm internal still the right direction for 2026 road use?
2. Is ~34mm max width ideal for modern 30mm tyre setups?
3. Would you prioritise lower weight or higher load/impact margin?
4. 20/20 rear — acceptable for modern road builds?
5. Any concerns with U-shape profiles at this width and depth?
Looking for constructive technical feedback rather than brand comparisons.
Appreciate any thoughts.
need 18 spokes front for aero, specialized does it on the newest rapide and its significantly faster than higher spoke counts.

I mean it's pretty obvious that less of the same spoke will be more aero, but spoke count shouldn't be just blindly reduced for the sake of it. The newer, thinner carbon spokes are often less or similarly stiff as a cx-ray and should probably be built with the same spoke counts as most steel spoke wheels. If the aim is to reduce spoke count, regular thickness carbon spokes that we've had for years now should be used.

If the aim is to reduce spoke count, regular thickness carbon spokes that we've had for years now should be used.
I would think the aero benefit of going 18/18 over 20/20 spokes is probably negligible and realistically insignificant.
I did look at regular carbon spokes for my latest wheelset (2.3 × 2 mm), but the lateral rigidity figures weren’t great even with a 21/24 hub. I also looked at 3.95 and 5.1 mm for my use case, and considering I’m not putting out crit-level power, that felt unnecessary.
The 3.1 mm spokes I’ve chosen still perform better than Sapim CX-Ray in terms of stiffness, and for my weight and power output they should be more than adequate with a 21/24 hub.
If I were going with a 20/20 traditional hub, I might have to rethink it — unless there are spokes with better performance values available.
I think lower spoke counts will be a thing this year and the soon to be released No6 wheels are following suit with 16/20.
Serious engineering considerations for lower spoke counts but I’m assuming generally the rim hub and spokes are all designed seperatly and not as part of a total system.
-
The relevant part of a carbon spoke for stiffness is the round part at the end of the spoke (2.2 and 1.85 respectively on the pictures I attached) which tells you how much material is in the spoke. The flattening of the middle section should reduce tensile stiffness by some small amount, but not enough to worry about. This could be thrown out of whack by using different types of carbon, but so far, most seem to be sticking to similar material.
Most regular carbon spokes are 2.2mm in diametre and about 30% stiffer than a cx-ray, the lighter ones tend to be around 1.8mm and somewhere in the region of a cx-ray.
A 2:1 radially laced on the NDS, 18 spoke front wheel with the same spokes and similar hub dimensions should be laterally stiffer than a 20 spoke wheel. You gain a tiny bit of aero and weight from reducing spoke count, so it's an all-round win on paper, but you concentrate the same total stresses on the rim over fewer spokes and it's a case-by-case basis of how much reinforcement is needed to account for that. So you end up ahead in some respects but behind in others.

Speaking of spokes. I need some help from you guys and girls to select spokes. I am planning on buying a pair of wheels for climbing, and want them as light as possible, but also durable. The roads here are not so good, and I travel frequently with the bike. I got a quote form Zen with 3.1mm carbon spokes. I have never had carbon spokes before, so got a bit worried. Should I be worried, or am I just overthinking? When I asked for a quote with steel spokes, I got a quote with "sapim cx ray spokes". Is this the "normal"? A bit cheaper, but also a bit heavier. Please help a man who knows nothing about wheels. 8)

I know that, but calling it "significantly faster" is just silly. It's marginal if any.

I’ve been using carbon spokes since 2019 without any issues. I’m in the UK and, like many places, the roads are far from perfect — but whether I’m on steel or carbon spokes, I ride with the same level of care. I personally don’t see a problem unless you’re the type who’s constantly smashing into potholes without noticing.
Zen probably offered you the steel spoke option as a value alternative. Modern steel‑spoke wheels are still very light, and Sapim CX‑Ray is the standard “go‑to” spoke for high‑quality builds.
If you want something lighter than CX‑Ray but still steel, Zen also build with Alpina Hyperlite, which a lot of riders are choosing now — they’re lighter than CX‑Rays and still very reliable.
Carbon spokes are absolutely fine if you want maximum stiffness and weight savings, but steel is still a great option if you prefer something more traditional and a little cheaper.

Info is proprietary but its significant for front wheels, rear wheels could use more spokes for pedaling stiffness. Don't have any data to give so I wont die on this hill.

For lightweight climbing wheels the 3.1mm carbon spokes are absolutely best option in my opinion. They are lighter but actually more durable (on paper at least). Been using different carbon-spoked wheels for 3-4 years now with no issues and don't see any reason to go back to steel.
If you still want to go with steel then CX-Ray is the popular choice. I have had to replace a few of those back in the days but nothing major.

Aerodynamics is everything but obvious. It seems obvious that less of the same spoke will be more aero, but spokes create some kind of turbulance/disturbance of the windflow. It wouldn't surprise me if less spokes create less than ideal windflow.
Not saying he's wrong. But I agree that it's a bold statement that needs some backing up.

Thanks for the feedback regarding spokes, Sander and RLA. Appreciate it. Gives me something (more) to think about. ;D

Good Day Forum Members :)
Thanks again for the feedback on the original post last week.
Some of the comments suggested looking at lower spoke counts, so we’ve been discussing whether 18 spoke front and rear might be feasible. However, this is still under consideration rather than a fixed decision.
With very lightweight rims (around ~340 g), spoke count becomes more important because the rim itself carries less material. The system needs to be considered as a whole — rim structure, spoke count, spoke tension and overall load limits — rather than just reducing spokes to save weight.
At the moment the rim design would still be based around 20/20 spoke drilling, with 18/18 being explored to see if it remains viable without compromising stiffness or load limits (target system weight around 120 kg).
Another trade-off we’ve been discussing with the manufacturer is rim profile vs weight.
Most of the current sub-1000 g wheelsets use rims around ~330 g, and they tend to be UV / hybrid profiles, largely because that shape uses less material and makes those weights achievable.
A fuller U-shape profile generally improves stability and tyre integration but tends to push rim weight higher as the wall thickness need to be thicker for this shape
So the current concept being looked at is roughly:
• ~50 mm depth
• ~25 mm internal width
• ~31 mm bead
• ~34 mm max width
• ~340 g rim target
• ~120 kg system limit
• ~ Softer U/V Profile
-
Good day everyone,
We have been looking at two possible rim profile options for a lightweight aero wheelset concept.
Depth would likely be around 50 mm (possibly 51–52 mm), with 25 mm internal width, optimised for 30–32 mm tyres, and a 120 kg system weight limit.
Two rim profile directions are currently being considered:
Option 1 – Mild U/V hybrid profile
• ~50–52 mm depth
• Rim weight ~340 g
Option 2 – Full U-shaped profile
• ~50depth (additional 1mm or depth adds around 2.5g so a 52mm would be 355g)
• Rim weight ~350 g
Using the current hub and spoke setup:
Hub set: ~235 g
Spokes (40 total): ~84 g
Approximate wheelset weights:
• U/V hybrid profile: ~999 g
• Full U profile: ~1019 g
So roughly a 20 g difference for the complete wheelset.
The trade-off seems to be slightly lower weight with the hybrid U/V profile versus a fuller U-shape which may offer better tyre integration and crosswind stability, particularly with 30–32 mm tyres.
Interested to hear which direction people here would lean towards.
-
For mi U shape is the choice. 1000 - 1150 is very aceptable weight.
-
I prefer wide u shape. For me this type is great in sidewinder, stability, speed.
-
Definitely U.
-
ideally, both. a 52mm U shaped front wheel with a 50mm U/V rear wheel would be the ticket.
-
I would want U-shaped, but in 58/64mm depth. Maybe make 52/58/64mm depth of these?
-
If its one rim I would do option 2. If you are thinking about as a product family, I would do one of each.
Product A: I would still do option 2, but increase the depth to at least 54mm.
Product B: Profile from option 1 and make a 64mm rim (or go as deep as you can without worrying about UCI legality due to mold inaccuracies).
This would give customers the opportunity to run a more stable and lighter wheel with the A/A, A all-round but still very aero set with A/B and for the people who want all-out speed, a UCI max depth wheelset with B/B
-
Dusted off the rim cfd setup for this. Caveats, this isn't professional grade stuff and it's only one orientation at a time, in a 2d plane, so not a representation of what drag on a whole wheel looks like, but still useful as an isolated comparison. Also debatable how accurately I eyeballed the shape of a tyre. The rim profiles were traced from pictures, but I think I hit those pretty well. 32 mm WAM tyre at 40 km/h, from 0 to 20° of yaw.
"Forward" orientation means the tyre is the leading edge, "reverse" means the rim is the leading edge. "Large r" is what most are describing as "U shape", "small r" what is being described as "UV".
Drag plot attached. Can see that the small r profile exhibits slightly lower drag at lower yaws, but it also stalls earlier, which could possibly indicate worse stability (THIS IS NOT A RELIABLE ASSUMPTION). The point of stall can by identified by the abrupt and sharp rise in drag, anything after that is unreliable data (or rather, even less reliable than it was in the first place).

large r reverse (https://postimg.cc/gallery/rmX23SS)
small r forward (https://postimg.cc/gallery/S24zHjZ)
for some reason, 4 links gets you filtered out so another in next post
Not sure if this is a case of bad data being worse than no data, but I have it so might as well show it, instead of just sitting on it.

Thanks everyone for all the feedback — really appreciate the time and input from so many members.
At this stage it looks like we’re still moving forward with the 50 mm full U‑shape direction. Current working spec is around 350 g per rim, 25 mm internal width, and 34 mm max external at the rim. Impact target is 100 J with a 120 kg system weight limit, optimised around 30–32 mm tyres.
I mainly wanted to get a consensus on whether people preferred the slightly lighter hybrid profile or the more stable full U, and the feedback has been very clear in favour of the U‑shape. Stability, tyre support and real‑world handling seem to matter far more than chasing the last 20 g.
As with all our rims, we will work to provide three weight options:
• ~350 g
• ~370–380 g
• ~400–410 g
Thanks again to everyone who commented — the input genuinely helps guide the development.

I'd like to do a mini review of the VaporLite Pro 50mm iw23 wheels with 3.1mm carbon spokes, which recently arrived.
Ordered on January 11, they arrived in Italy on March 9... At least the shipping was fast, less than two weeks.
Unfortunately, the box arrived damaged, and I feared the worst.
Luckily, only the protective side cover was broken; I advised Zara to use sturdier cardboard.
I found all the spare spokes, tape, and tubeless valves.
The wheels weigh 450g + 555g = 1,005g less than the estimated weight.
They were fitted with RideNow and GP5000 28mm latex tubes with no effort.
I checked the tension and both are within 5% (report attached), while the truing and roundness are within +/- 0.10mm.
I'd say they're well-aligned and tensioned, and most importantly, they look fantastic—much better than in the photos!
The only thing I noticed is the slightly off-center camber on the front wheel 0,6mm on the DS side and the rear 0,15mm on the NDS side.
For now, I'll try them that way.
Last but not least, I appreciated Zara's support and expertise!

Hi @GPC,
Thank you very much for taking the time to share such a detailed mini‑review of your VaporLite Pro 50mm iw23 wheelset — we really appreciate it! :D
I’m very happy to hear that the wheels arrived safely, performed well in your initial checks, and that the real‑life appearance exceeded expectations. The tension report and trueness measurements you shared look great, and it means a lot to us that you recognise the effort we put into quality control.
Thank you also for highlighting the shipping box damage. Even though the wheels were not affected, this is something we take seriously. We have already started reviewing stronger carton options with our packaging supplier to prevent similar issues in the future.
And thank you again for your kind words about our service. We’re always here to help before and after purchase.
Wishing you many great rides with your new wheels! :) ;)

Hi Zara,
Thanks for the discount code and all the options.
I'd like to build up a lightweight set of wheels, but want to use brass nipples, as our weather is generally terrible and want to be able to actually use them without worry of galvanic corrosion.
Is it possible to build any of the carbon spoked wheels with brass nipples or would we have to look at something like the alpina or titanium spokes for such a build?
My target is a 55mm set of wheels coming in around 1200g if at all possible.
Thank you.

Hi,
Thanks for the question—and just to add a bit more clarity on options and pricing:
We don’t monitor this forum very frequently, so for any enquiries or orders, the best way to reach us is via WhatsApp (details let the bottom). You can also DM us on our Facebook or Instagram pages and we’ll get back to you as soon as possible.
In terms of your build:
- Carbon spoke wheels use proprietary nipple systems, so they can’t be paired with brass nipples
- For brass nipples, we’d recommend Alpina Hyperlite or similar steel spokes such as Sapim CX Ray
For long-term durability—especially in wet or winter conditions—we generally recommend stainless steel spokes with brass nipples rather than titanium. While titanium is corrosion-resistant on its own, when paired with brass nipples it creates a higher risk of galvanic corrosion over time, particularly in salty or consistently wet environments. Titanium is also more sensitive to installation prep and can be more prone to thread seizure if not perfectly treated. In contrast, stainless steel spokes with brass nipples are a well-proven, industry-standard combination that offers excellent corrosion resistance, more consistent long-term reliability, and easier servicing.
Spoke weights (Alpina Hyperlite):
- ~3.8–3.9 g per spoke with nipples
- ~4.0 g we round up to
- ~4.8–4.9g with brass nipples so round up to 5g
---
### Wheelset options
Option 1 – Lightest 55mm build
- VaporLite 55 mm rims (370 g each)
- ZC240RS hubs
- 24/24 spokes (Hyperlite)
- Approx weight: 1220 g ±30 g
- Price: $849 USD (Promo: $799 USD)
Option 2 –
- ZC261RS hubs
- Hyperlite spokes
- Approx weight: 1249 g ±30 g
- Price: $839 USD (Promo: $789 USD)
---
### Weight optimisation option
If you want to push closer to ~1200 g:
- Use a 50 mm front rim (330 g) + 55 mm rear (370 g)
- This saves ~40 g
---
All stated weights are ±30 g as standard for handbuilt wheels.
Feel free to reach out via WhatsApp or social DMs and we’ll help you fine-tune the perfect build.
Thanks!X

Superb level of detail Zara, thank you.
I’ll get in touch with you to sort the details privately.

Given the quality and pricing of our wheels, it’s not something we’re able to include. For context, comparable 50mm sub-1000g wheelsets from competitors typically range from $1799 to $2250 USD.
That said, we do offer tax-free shipping depending on the region:
• Most of Europe & the UK: $110 USD
• USA: $135 USD
Let me know your location and I can confirm the exact rate for you.

You’re right. I was lazy.
Next time there’s a promotion I’ll contact you directly.
But just as a suggestion it could be easier if there was an up to date webshop with current listings so customers do not have to browse through instagram posts and forum pages.

I would suggest contacting Zara via WhatsApp or Instagram. I also did so last year. Ordered a wheelset for my gravelbike via Instagram DMs which first felt kind of weird but the communiation with Zara was super easy. She replied within hours and so we could find a custom solution that fitted to my demands quite easily. I am super happy with this wheelset and will definitiely place another order within the upcoming weeks.

Can’t wait to receive my pair of 65mm VAPORLITE ULTRA!! Silver hubs
Advertised at 1109g (!!!) I will report back and detail the whole process, weighing & measuring everything.
I’m 64kg so no worries about weight limit here
-
Hey all Just received a set of Zen wheels for a mate from my cycling club who’s new to this side of things, so thought I’d share some details for anyone interested.
These are a 60mm front & rear setup, U-shaped profile:
25mm internal width (hooked)
32mm external width (bead)
~34mm max width at the widest point
He races a mix of TTs, road races, and crits, so wanted something that balances aero, stiffness, and reliability rather than chasing absolute weight.
Spec:
100kg rider weight limit
ZC270RC hub (similar to H-works SR270 style)
Shimano 11-speed HT freehub
Steel bearings
20 spokes front & rear
3.95mm carbon spokes
UD matte (paint-free) finish
Claimed weight: 1276g ±30g
Actual weights:
Front: 585.8g
Rear: 710g
Total: ~1296g
So around 20g over claimed, which is pretty reasonable.
The RIM spec, hub and weight is pretty much Identical to the 8Lien Wide Version Disc Carbon Wheelset (25MM Inner) L6W. https://8lienbike.com/products/best-aero-wheels?variant=49347976626462
What’s included:
Tubeless valves
Tubeless tape installed
3 spare carbon spokes
Timeline:
Ordered: mid-March
Build time: ~6 weeks
Shipped: 15th April
Processed via Chinese agent: 17th April
Delivered (DPD UK): 26th April
Overall, pretty smooth process considering it’s a custom build.
He’s picking them up this evening, so will be interesting to get some real-world feedback once they’re fitted and ridden.
He’s planning to run 30mm tyres on a 2020 Scott Foil, so should be a quick setup once built up and he is confident they will fit his bike!

I'll get back later then to check if you have decided to make them available in deeper variations also. These U-shaped VaporLite II are the only design you have that i'm interested in, otherwise not worth upgrading from current wheels i have.
58/65 is what im primary looking for, but 55/65 or 60/65 would also work.👍

New 65mm front and rear wheelset is finally on its way to Rhinos Workshop for the Quick Pro ER One build shippied yesterday!
Ordered February long wait was due to request for hidden spoke nipples and waiting for the manufacturer to develop there hidden nipple system and test it.
Specs:
* 25mm internal width
* 32.4mm external width
* THR Industries R2 hub (2:1 ratio)
* UD paintfree Gloss Finish
* Superlight 100-110kg load limit
Front wheel:
* Estimated weight 1234g actual 1252g
* 21 spokes
* 14 cross-laced on the disc side
* 7 radial laced
Rear wheel:
* 24 spokes
* 16 cross-laced on the cassette side
* 8 cross-laced on the disc side
Built with 3.2mm bladed carbon spokes and hidden nipples.
This wheelset took considerably longer to lace due to the hidden nipple system. The tight internal rim tolerances leave very little room for variation, so additional spokes had to be ordered in +/- mm increments to prevent the nipples from protruding beyond the rim.
On top of that, lacing the R2 hub—with its 2:1 pattern—is more time-consuming compared to a traditional 1:1 hub build.
-
dang, that's a really good looking pair of wheels - i much prefer the look of the more narrow blade depth on carbon spokes. great weight too considering not eking out every saving for a weight weenie build.

Cheers — I was aiming for a proper performance / weight-weenie build.
I could’ve gone all-in with one of the ~230g 20/20 spoke hubs and dropped from a 425g rim to something like 395g, which would’ve put the wheelset around the 1100g mark.
But I already had the DFS 55/55 and R2 built up with 3.2mm spokes, and honestly, the wheels have been excellent so far — stiffness is really solid.
I did consider going up to 3.8/4mm spokes on that setup, but after riding them, there’s just no need. Because of that, I stuck with a similar approach on the 65s, and with 24 spokes in the rear you obviously get the stiffeness with the slimmer spokes
I’m currently out in Mallorca riding the 55/55 DFS setup, and they’ve been great on the climbs — really responsive.
I went with the R2 hub mainly for its ability to balance spoke tension and improve lateral stiffness, but I won’t lie — the aesthetics played a part too. They’re a seriously good-looking set of hubs.
Will be interesting to see what my mate Ryan thinks once they arrive and get built up.
I know it’s a fairly standard open-mould profile, and realistically most places could source something similar if you spec the same hub. You do pay a bit extra for that, but even so, at around £800 delivered, it’s hard to argue with the value.
The only thing is I’m riding 28mm tyres on the 55s but I’m definitely going to move to a 30/30mm and 30/32mm set up once the tyres need replacing same with the 65s as I already have a set for the build

Man it’s hard to keep track of your wheel adventures!
-
@Sander2177 i like your 55/55 build. I have been pondering building up something very similar but most likely a 55/60 for my SL8. I have been running mid-depth 45's that i'm mulling moving to my gravel bike. still undecided if i want to do a 3.1mm carbon spoke build or a light weight steel spoke build - i do like the serviceability of steel spokes plus the slight comfort improvement. trade offs are weight and stiffness of course.
i'd do a 60/65 but the crosswinds can get silly in the coastal areas near me.

20/20 carbon spokes? 3,1mm?
Correct me if I am wrong, but these narrower spokes are supossed to be about as strong as steel spokes.
So, that is as you would only put 20/20 steal spokes on a GRAVEL wheels!
I would understand if 3,8mm spokes were used.

@Sander2177 i like your 55/55 build. I have been pondering building up something very similar but most likely a 55/60 for my SL8. I have been running mid-depth 45's that i'm mulling moving to my gravel bike. still undecided if i want to do a 3.1mm carbon spoke build or a light weight steel spoke build - i do like the serviceability of steel spokes plus the slight comfort improvement. trade offs are weight and stiffness of course.
i'd do a 60/65 but the crosswinds can get silly in the coastal areas near me.
Sweet! I orderd a 55/60 setup a week ago with Zara. See attachment for details.
-
The only thing is I’m riding 28mm tyres on the 55s but I’m definitely going to move to a 30/30mm and 30/32mm set up once the tyres need replacing same with the 65s as I already have a set for the build
Will 32mm tires fit on your SL8 or X68? Max tire clearance is 32mm, right?

I wanted to share my experience with a set of ZEN 60/55 lightweight rims and hopefully get some input from riders with similar specs.
First off, credit where it’s due: ZEN has handled everything so far in a very professional and supportive way. Every time an issue came up, they responded accordingly and covered the costs to resolve it. That level of service deserves recognition.
Background / setup:
- ZEN 60/55 lightweight rims
- 24mm internal width
- SR270 hub
- 20x 3.1mm (2.1gr) carbon spokes (front & rear)
- System weight limit: 135kg
- Rider: 85kg, FTP ~340W, sprint ~1300W
- Tires: 30mm road + occasionally 38mm gravel (on a frame rated max 38mm)
Initial issue:
After the first rides, I noticed the rear drive-side spokes rotating (bladed spokes losing alignment). ZEN offered to cover a local rebuild/straightening -> great service. Unfortunately, the issue came back twice.
At that point, I suspected the spoke–hub interface might be the root cause (spokes rotating under load). ZEN agreed and sent a new hub + T-head spokes to eliminate that variable. Again, fully covered.
Current situation:
With the new setup, the spoke rotation issue seems resolved. However, under high load (especially sprinting), I’m now noticing:
- Audible movement/“working” from the rear wheel
- Tire rubbing the chainstay (this was already the case with the original spokes)
- Overall feeling of flex under power (this was already the case with the original spokes)
Given my weight and power numbers, I’m starting to question whether this wheel configuration is simply too light / not stiff enough for more aggressive riding.
What I’m trying to figure out:
- Are other riders (~80–90kg, similar power) experiencing comparable flex with lightweight carbon-spoke setups?
- Is this a known limitation of this kind of build (low spoke count + carbon spokes)?
- Or does this still point to something being off in my specific rear wheel?
To be clear: this is not a complaint about ZEN’s service, they’ve been excellent throughout. I’m mainly trying to understand whether I’m running into a design limitation versus a product-specific issue.
If others with similar rider profiles have experience with this type of wheel (especially carbon spokes / low spoke count), I’d really appreciate your input.
-

Of course it’s a 32c frame but 34 will fit
I’m planning at 30/32mm combo at some point should measure 32/43

Wheel rub can often be a combination of both the wheel and the frame, not just one factor.
From a technical standpoint, going to thicker spokes (for example 3.95 mm or 5.1 mm) would improve stiffness without a huge impact on performance. You could also consider a slightly heavier rim layup, which will add stiffness and stability under load.
Another option would be changing the hub and spoke configuration. For example, the H-Works SR288 hub with a 20/24 spoke setup, or even increasing rear spoke count further.
In your case, I’d say the main improvements will come from either:
* thicker spokes
* or increasing rear spoke count (24h or more)
Both should help reduce flex and eliminate the rubbing you’re experiencing.
It might also be worth asking if you can purchase just a rear wheel with a stiffer build to test the difference.

Thanks for your input, Sander. I appreciate it, especially given your experience with different wheel builds.
Out of curiosity: what’s your take on the stiffness of a 20/20 setup with 3.1mm spokes for a rider in my range?
I agree tire rub isn’t just a wheel issue. For context, this is on a Lightcarbon LCR018D. I’ve also used the wheels on another frame with more clearance. No rubbing there, but the rear still felt relatively flexible under load (subjective, but noticeable).
On the Lightcarbon, I can deflect the rear wheel into the chainstay by hand without excessive force. Combined with the audible “working” under sprint load, that suggests to me the rear wheel isn’t meeting my requirements.
I understand the ways to increase stiffness (thicker spokes, more spokes, different hub), but I’m trying to determine something more fundamental:
is this behavior expected for this configuration, or is my rear wheel an outlier?
I specifically chose this rim (135kg system limit) to have a reasonable margin for strength and stiffness at my weight/power. If this setup is inherently at its limit for riders like me, that’s useful to know, but then it’s more about application clarity than a one-off issue.
So my main goal here is to understand: is this a design limitation, or a product-specific problem?

Perfect — your hub actually explains why your wheels feel solid even on 3.1 mm spokes. You’ve got a much stiffer system, not just a different spoke count.
Here’s your final reply with your hub comparison added properly and factually:
⸻
Yeah, I think there are a couple of things getting mixed together here: what you can do to a wheel by hand, and how it behaves under real riding load.
You can deflect pretty much any wheel far enough by hand to touch a chainstay if you try. I can do it with my own wheels too, and those ride completely fine under power. That kind of static test just isn’t a reliable indicator of real-world stiffness.
When you’re riding, the wheel is rotating and loads are distributed dynamically through the spokes. That’s very different from applying a static sideways force with your hands. All wheels flex — that’s normal. What matters is how they behave under load.
⸻
Where things become clearer is the actual build and hub configuration.
Your setup:
* 20 front / 20 rear
* 1:1 lacing (10 per side)
* 3.1 mm spokes
* fairly standard flange geometry (around 53 mm / 42 mm rear)
For example my setup on a set of wheels with R2 hub (also 3.1 mm spokes):
* 21 front / 24 rear
* 2:1 lacing
* rear: 16 spokes drive side / 8 disc side (3-cross on drive side)
And importantly, my hub geometry is very different:
* Rear drive-side flange: 74 mm (very large)
* Rear disc-side flange: 45 mm
* Asymmetric flange design
* 56 mm flange spacing
That makes a big difference.
⸻
Why this matters
1. Spoke count (rear)
Going from 20 → 24 spokes = +20% spokes
That alone improves how load is shared and increases lateral support. It’s not a perfect 20% stiffness gain, but it’s significant
2. Flange diameter (huge factor)
Your hub: ~53 mm drive side
My hub: 74 mm drive side
That’s not a small change — that’s a massive increase in bracing leverage.
A larger flange increases the bracing angle, which directly improves lateral stiffness. This is one of the biggest contributors to how “stiff” a wheel feels under load.
3. Lacing pattern
* Your wheel: 1:1, evenly split
* Mine: 2:1 with more spokes on the drive side + 3-cross
That puts more structural support where the torque actually is (cassette side), which improves resistance to flex under sprinting.
Spoke thickness trade-off
* 3.1 mm spokes ≈ 2.1 g
* 3.95 / 5.1 mm ≈ 3.5 g
Total saving: ~50–60 g
But:
* 3.1 mm ≈ 80 kgf lateral rigidity
* 3.95 / 5.1 mm ≈ 115 kgf
→ ~40% increase in stiffness capacity for basically a gel’s worth of weight
Putting it all together
Your setup:
* low spoke count (20/20)
* thinner spokes (3.1 mm)
* standard flange geometry
* even spoke distribution
My setup:
* higher spoke count (24 rear)
* much larger drive-side flange (74 mm)
* asymmetric 2:1 lacing
* better bracing angles
Even though we’re both using 3.1 mm spokes, the overall system stiffness is not comparable.
⸻
Bottom line
I don’t think your wheel is defective.
I think you’re hitting the limits of a very lightweight configuration (3.1 mm + 20/20 + standard hub geometry) at your power level (85 kg /1300 W).
- Hand-flex test not meaningful on its
Real load behaviour that’s what matters
Your symptoms (flex, noise, rub) consistent with a stiffness limit
If you want to fix it, the biggest gains will come from:
* more spokes (24h rear or more)
* or thicker spokes
* or both

Were all your wheels set up like this? This seems to refer to your latest purchase.
Otherwise your AI analysis does not really cover his question wrt to your extensive wheel experience.

With all the expertise I’ve seen in this thread so far, could someone give me a wheelset configuration for my climbing bike build. I currently own an XMCS set, 1100+ g, 45mm rim. However, everytime I go downhill at 40+ mph speed, the front wheel wobble. i want to build a new set: ultra lightweight and lower rim height to avoid crosswind effect. However, with other factors like hubs, hub flange, spoke count, spoke width, etc. I’m lost. Please give me a configuration like you would give it to Zara. I’m 145lbs (~65kg).

My AI analysis thanks for pointing out Tines Still requires me to put the information into and dictate into it.
All it gives me back when I request the information is it in a refined manner.
So am I not allowed to use AI? or to keep people like you happy should I highlight in my reply?
Instead of pointing and criticising my use off AI and obviously trying to be a smart arse why don’t you try and help answer the question? Otherwise keep your thoughts to yourself.
I don’t claim to be any expert all I try and do is help people who know less than myself and there are others here who know more that’s it.
Absolutely nothing wrong with using AI to refine my answers and improve grammar and spelling
Simple answer to his question
He needs thicker carbon spokes
Or go
20/24 or 24/24 spokes with 3.1mm
Or
20/24 or 24/24 spokes at 3.95mm or 5.1mm as they are about 40% stuffer
And will then give him a stuffer Wheelset

Front Wheel on your bike may need balancing to stop the wobble.
I cannot guarantee and spec given will stop wobble.
You can get a 36mm depth Wheelset 20/20 spokes is like 879g
With a 20/20 spoke hub they are all very generic those days flange sizing is pretty similar

Absolutely nothing wrong with using ai. Ai is useless without the input. Your reply was very clear and informative but didn't really give an answer to what your experience is with the wheel configuration that I chose.
I'm aware what needs to be done to get a stiffer wheelset, but I didn't think I was pushing the limits with the configuration that was recommended to me by Zara. Therefore I would be quite disappointed tbh if I now have to buy another wheelset. When inquiring about the possiblitities I even stated "I'm an 85kg rider and prefer strength over super light weight".
I don't think my values are that abnormal?! If this is a limitation for this configuration people should be made aware of this. I would have happily chosen a different configuration if I knew.

Appologies if my answer was not what you wanted and overly complicated
Thing is a lot of the lightweight wheel on market are using 3.1mm spoke simply for weight reduction. If you’re a lighter rider great and have similar stiffness to a 24/24 steel spoke wheel albeit they are marginally stiffer laterally as they have no stretch like steel.
I have a mate who has just got some wheel for racing and with his numbers he went with 3.95mm on 20/20 spokes. 80kg 1500watt territory.
Your values are not abnormal it’s just a bit of a mine field when buying wheels these days with the amount of information available unfortunately and alot of branded wheels don’t give you all the information.
Don’t get more wheels it’s a pain in the arse but if it’s only the back wheel get some 3.95 spokes and re-lace the back wheel only

Sorry if this made a wrong impression, the analysis by AI was thorough and interesting but I just wanted to point out that it missed his question.

I have about the same wheels as you although mine are 50/55mm. 3.1 carbon spokes, 20/20.
I am about 78kg.
I just tried the deflection test and can't get it anywhere near the stay. Maybe 2mm of movement, max.
My wheels are quite stiff in a sprint. My sprint power is just shy of 1400 watts and I don't feel anything I would describe as flex in the rear.

This will be first set of carbon wheels. Ive spoken to Zara, and she's been amazing, replying to all my questions and been accommodating my budget. Shes sent me this wheelset plan. And I wanted to post it here to ask for your recommendations.
I live in Urban Australia, our landscape isn't flat, and I do have to climb small hills and do alot of twists and turns on my daily commute to work and the weekly group rides. Im upgrading from my stock Giant PR2 wheels (1.9kg) to these Zen wheels for about $700.
My question is that. As im not a crit racer or planning to climb the highest hills locally. Do I need such light wheels? Scrolling on weightweenies and chinertown and everyone always wants to go as light as possible. But does it mean im trading weight for the stability and toughness of let's say a paid of 1300g wheels?
Please give me tips. Do I need these super light weight wheels or should I save the budget and go for normal weight at about 1300g?

It depends on many things, but in most cases you do not need to go the lightest possible option. 1200-1300g is absolutely great for a wheelset. If you don't mind, how much do you weight?
Weight distribution is also a thing when looking at a wheelset. The closer to the axle the less the weight matters. That means you could go for a hub that has proven to be reliable, like H-Works SR270 or THR R2 possibly, with no real performance loss (maybe even a perf gain?). Pillar 1420 spokes are probably okay. Rim weight option depends on rider weight and power output but it wouldn't hurt to go with just slightly heavier option that might make a stiffer wheelset overall. With those changes you'll still end up with <1300g wheelset most likely.

That means you could go for a hub that has proven to be reliable, like H-Works SR270 or THR R2 possibly, with no real performance loss (maybe even a perf gain?). Pillar 1420 spokes are probably okay. Rim weight option depends on rider weight and power output but it wouldn't hurt to go with just slightly heavier option that might make a stiffer wheelset overall. With those changes you'll still end up with <1300g wheelset most likely.
Could not have said it better myself!
And everyone does chases numbers I'm guilty of that also but performance comes first and 1200g - 1300g is still light.
Like RLA said what your total system limit, you the bike bottles, clothing the lot considering these are a 90kg Load Limit Rims

I am 67kgs. My bike is about 9kgs with the stock wheels. So even if im fully kitted out, im below the 90kgs limit. Should I still stick to the rims Zara recommended tho, I believe they are the vaporise, or should I switch for a slightly heavier (but cheaper) rims?
My requirements are 40mm depth, steel bearings, steel spokes (cx ray), 36t ratchet (cuz i heard theyre more durable than the 54t), with 23-25mm internal (im running gp5000 32s).
If not the vaporlite. What you recommend the setup be?

If you want a robust wheelset then getting a bit heavier pieces usually give you that. Not always, but usually.
My personal recommendation would be: SR270 or ZC270RC hub, CX-Ray spokes, rim would be U-profile, 40mm depth, 25 IW, 34 OW, 385g (110kg), image attached.
Should be plenty stiff and reliable for years.
-
If your using 32mm tires, and maybe 35 in the future? I would directly go for a wider rim - Zen has a 28/37 don't they? That will be perfect for 35 and 32mm tires, while the above is perfect for 30 and 32mm tires. I would chose the midweight option in the front, and the standard weight in the back (well I would always go deeper in the back if it's possible. 40mm in the front for less problems in wind, and 50 or 60 in the back)

Good day Forum Members
For those of you who many be considering the VaporLite II Wheelset please find attached photos including sectional cut through showing the spoke hole reinforcement inside the rim.
Spoke hole tensil strength exceeds well over 300kgf in testing.
Rims Estimated Weight 350g as Pictured 337.6g

Bought a set of wheels from Zen and I couldn't be happier.
The rims are the U shape, 60mm depth, normal weight version, 51mm carbon spokes.
The wheels came out beautiful and without any defects, weight is around 1400g as advertised, and I had the option to customize the paint style and decals.
Had no trouble with shipping, they sent them out on time, and most of all customer service was impeccable.
Texted with them on WhatsApp and they always replied as soon as possible, even at late hours for them in China.
Overall couldn't be more satisfied, I'll report back after 100km as well but I can't wait to try them out.
Absolutely recommend them, especially for their professionalism and excellent customer service!

Received the 65mm Vaypor Lite pair weighing 1140g with 3,2mm carbon spokes.
Will make a more detailed « review » soon, so far very pleased.

New 18Hole Carbon Spoke Road Hub
Hi all,
We have been developing a new 18-hole road hub platform using a 2:1 spoke layout (front and rear).
The hub is in the testing phase, and we would like to share the current technical specifications and design considerations.
Technical Overview
Spoke holes: 18H front / 18H rear
Lacing pattern: 2:1 (front and rear)
Estimated weight: approx. 250g (set)
Material
Hub shell: AL7075
Freehub body: AL7075
Axle: AL7075
Axle standard:
Front: 100mm
Rear: 142mm
12mm thru axle
Bearings:
Front: 2 × 6802
Rear: 1 × 15267 + 3 × 6802
Freehub system:
Ratchet (36T / 60T)
Flange Geometry
Front: 42mm / 42mm
Rear:
Drive side: 53mm
Non-drive side: 42mm
The larger drive-side flange is designed to support higher spoke load and improve stiffness in a low spoke count configuration.
Spoke Layout
18H with 2:1 lacing:
Rear: 12 spokes drive side / 6 spokes non-drive side
Front: 12 / 6 split
This layout improves tension balance compared to a traditional 1:1 low spoke count design.
Up to 4.2mm Gauge Carbon Spokes
Build Characteristics with reduced spoke count:
Each spoke carries higher load
Rim spoke holes are subject to greater stress
It is more difficult to achieve very low lateral runout compared to 20H builds
Rim Compatibility and Testing
This hub is not limited to a specific rim model and will be available for different wheel builds.
During testing, we are focusing on more reinforced rim structures, as these are better suited to the higher spoke loads in an 18H design.
For example:
The reinforced version provides improved spoke bed strength, structural stability, and long-term durability. For this reason, reinforced layups are recommended for most riders.
Original VaporLite Compatibility
Use with extreme ultralight rims such as the original VaporLite 23/25mm inner (50mm Depth Rim ~330g) is still under evaluation due to the lightweigh nature of this rim. A Lateral runout of 18 holes will be at 0.3mm, but if race ready version VaporLite Rim is used (50mm Depth Rim ~380g) its will be 0.2mm, so suggest heavier layup version in long term using.
For Orginal VaporLite Model in the lightest rim layup the following conditions would apply:
System weight not above 90kg
Smooth road use only
Frequent checking of spoke tension and wheel runout required
User maintenance or professional servicing required
This type of build prioritises minimum weight over durability and long-term stability.
VaporLite II
This hub is suitable for new VaporLite II rims.
Availability
Estimated availability: 4–5 weeks

No sir 😉
We’re now seeing a shift toward ultra-wide gravel rims, with modern gravel bikes offering increased frame clearance — in some cases accommodating up to 60c tyres.
At the same time, we’re also seeing a resurgence of 32” (32er) wheels, with several Western manufacturers preparing to release new gravel and MTB frames designed around this format.

Ultra Wide Gravel Wheel ordered.
Went for the following specs:
Rims: 60mm Hookless 38mm IW, paintless w. Laser logos
Spokes: 24/24 Alpina Hyperlites w. hidden nipples
Hubs: Z235Rc hub w. Ceramic bearings
Estimated weight: 1417g
Essentially aiming to make a slightly more extreme version of the ENVE G SES 6.7 Pros.

HUB Update
Hi everyone, we’ve got an update on our hubs.
Our previous lightest hub platform, the ZC235Rc (20h front and rear), has been used across a wide range of our builds, including the VaporLite range of wheelsets.
We now have an updated version of this platform — the ZC215Rc — a newly optimised 20h front and rear hub with 20g shaved off, bringing the weight down to just 215g per set! :D
Alongside this, we’re also introducing a new addition to the range: the ZC235Rc 2024, now available in a 20h front and 24h rear configuration, weighing 235g per set.
As an example, the new VaporLite II will now achieve a claimed weight of 999g utilisimg the ZC215Rc , down from 1019g.
These hubs are now available across our full rim range. :D

Hi @ZenCarbonBike and everyone 👋
I'm building a new 700C aero gravel bike (frame max tire 50C, flat-mount 160mm, 12×100/142). I'll most likely run a SRAM XPLR AXS 1×13 groupset (not 100% decided yet — but if so I'd need an XDR freehub). I've seen the 45mm hooked / 32mm internal / 40mm external superlight gravel rim posted here and I have a few questions before ordering:
Tire range: what's the recommended min/max tire width (ETRTO) for that 32mm-internal gravel rim? My frame tops out at 50C and I'll likely run 40–45C — is the 32mm internal actually meant for wider/"60c" frames? Would one of your 25–28mm internal gravel rims be a better match for me?
Freehub: is XDR available on the ZSL / ZC270 / SR270 hubs (in case I go SRAM 13-speed)?
Spokes: for gravel use at ~70 kg, would you recommend the 24/24 Sapim CX-Ray build over the 20/20 carbon-spoke one? I saw a report here of carbon spokes rotating on the rear under load on gravel.
Hub/spoke combinations you offer for gravel (hole counts, ratchet, bearings) and the weight of each.
Rim bed: is a no-holes (tubeless, no rim tape needed) option available?
Other options / recommendations: is there anything else in your gravel range you'd suggest for my setup that I might have missed? I'm open to advice on the best depth / internal width / hub / spoke combo for an aero gravel build on a 50C frame.
Thanks a lot — really impressed by the feedback in this thread! 🙏

Hi @Grailstore,
Thanks for your questions.
Tyre size
The 32 mm internal rim is best suited to 45–60C tyres. If you’re mainly planning to run 40–45C tyres on a frame with a maximum clearance of 50C, I’d probably recommend one of our 25 mm or 29 mm internal width gravel rims instead. They provide a slightly more rounded tyre profile and are a better match for the tyre sizes you’re planning to use.
Freehub compatibility
Yes. All of our current hubs are available with Shimano HG, SRAM XDR or Campagnolo freehub bodies, so SRAM XPLR 13-speed isn’t a problem.
Spokes
At around 70 kg rider weight, I’d be happy recommending either a 20/20 carbon spoke build or a 24/24 Sapim CX-Ray build. Both are excellent options.
The carbon spoke wheelset is lighter and slightly stiffer, while the Sapim CX-Ray build offers a little more compliance and is easier to service if required.
Regarding spoke rotation, this generally only occurs on older straight-pull carbon spoke systems. All of our latest carbon spoke hubs use T-head carbon spokes, which locate positively in the hub flange and prevent the spokes from twisting under load.
Hub options
We have a wide range of hub options depending on your riding style and preferred spoke type.
Carbon spoke hubs
* ZC215RS – 215 g – 20/20
* ZC235RC2024 – 235 g – 20/24
* ZC245RC – 245 g – 24/24
* ZC276RC – 276 g – 20/20
* ZC288RC – 291 g – 20/24
Steel spoke / all-road & gravel hubs
* ZC240RS – 240 g – 24/24
* SR261 – 268 g – 24/24 (all-road)
* SR308 – 301 g – 28/28 (gravel)
* SR330 – 326 g – 24/24 (heavy-duty gravel)
All hubs use a 36-tooth ratchet system as standard, with an optional 54-tooth upgrade. Steel and ceramic bearing options are available across the range.
Spoke options
We currently offer:
* Sapim CX-Ray
* Pillar steel spokes
* Titanium spokes
* Carbon spokes in 3.1 mm, 3.25 mm, 3.95 mm, 4.5 mm, 5.1 mm and 5.9 mm versions.
We also offer hidden nipples for both steel and carbon spoke builds where compatible.
Rim bed options
Yes. We can manufacture both traditional spoke-hole rim beds and no-spoke-hole tubeless rim beds.
For carbon spoke wheels, we can also produce no-spoke-hole rims. However, hidden internal nipples aren’t available with every carbon spoke configuration.
My recommendation
For your build, I’d probably recommend a 45–50 mm deep rim with either a 25 mm or 29 mm internal width, depending on your preferred tyre size. For 40–45C tyres, I’d generally lean towards the 25 mm internal option.
For the hub, I’d recommend either the ZC240RS with Sapim CX-Ray spokes or the ZC235RC2024 with carbon spokes. Both make excellent aero gravel wheelsets, with the carbon spoke version being lighter and slightly stiffer, while the Sapim CX-Ray build offers excellent durability and easy servicing.
If you’d like more detailed recommendations or pricing, feel free to contact us via WhatsApp or email and we’ll be happy to help you choose the best combination for your riding.

Can you give more information about the impact test.
The VaporLite II has been designed to offer different performance levels depending on rider priorities, while maintaining high impact resistance across the range.
We currently offer three layup options:
Extreme Ultralight
* Rim weight: 350 g
* Rider weight limit: 120 kg
* Impact test rating: 110 J
Race Layup
* Rim weight: 380 g
* Rider weight limit: 120 kg
* Impact test rating: 110 J
Heavy-Duty Layup
* Rim weight: 410 g
* Rider weight limit: 130 kg
* Impact test rating: 120 J
The impact rating is determined using a controlled vertical drop impact test on a fully built and tensioned wheel, with no tyre, inner tube or tubeless tyre fitted. A weighted impactor is dropped directly onto the bare rim, making this a particularly demanding test because there is no tyre to absorb or dissipate any of the impact energy. The impact energy is measured in joules (J).
To put these figures into context, many premium ultralight carbon road rims on the market are typically tested to around 90–100 J, while the UCI minimum impact requirement for wheel certification is 40 J. Even the lightest VaporLite II layup exceeds those figures, while the heavy-duty version achieves an even higher impact resistance.
Rather than producing a single rim, we’ve developed three different layups so riders can choose the balance that best suits their needs—whether that’s the lowest possible weight, race performance, or maximum rider weight capacity and impact resistance.
-
At 110 J, what are the pass criteria? Does the wheel show no visible cracking or delamination and remain within specified radial and lateral runout limits? Also, what impactor shape and padding are used? I am trying to understand whether the 110 J figure is directly comparable with the ISO/UCI wheel-impact test and what condition the wheel remains in after the impact. sorry for all the questions. I'm really interested in purchasing a vapour lite II wheelset.

The VaporLite II wheel uses the same vertical impact test standard as the UCI. The test is carried out on a fully built and tensioned wheel with the tyre removed.
Test parameters:
● Impact energy: 110 J (±5%)
● Impact striker: Flat steel anvil fitted with a 20 mm silicone pad
● Striker mass: 6–10 kg, with the drop height adjusted to achieve 110 J of impact energy
● Impact location: 90° from the valve hole, between two spokes
● Number of impacts: One
Pass criteria:
● No visible cracking or delamination of the rim.
● Radial and lateral runout must not change by more than 1.0 mm after the impact.
I hope that helps, but if you have any other questions, please don’t hesitate to ask.

Can anyone comment on the crosswind stability of the new Vaporlite II wheels? I'm looking to build a lighter set of wheels for my new Cervelo S5. The Reserve 57/64 are very good in cross winds and fast but are pretty hefty. I'd like to build something with similar depths, widths, and carbon spokes but 300+g lighter. The Vaporlite II seems like a great option, but if they aren't good in crosswinds (I live in a windy area) I'll just stick with what I have.
I understand the physics of more rotational weight should inherently make a wheel more stable. But what are people finding with Vaporlite's? and what depths are you running?
One last question, standard DT ratchets and freehubs compatible with the hubs being used on the ultra and pro series?

Thank you for your interest in the VaporLite II wheelset.
As the VaporLite II rim was only officially released on 28 May, customer wheelsets are only just starting to be built and shipped. For that reason, there is currently very little independent real-world rider feedback available regarding crosswind performance.
From a design perspective, the VaporLite II uses a modern U-shaped rim profile with a 34mm external width and 25mm internal width. This profile has been developed to provide predictable handling and improved stability in crosswinds.
It’s also worth noting that crosswind stability is highly subjective and varies from rider to rider. Factors such as wind strength, local terrain, rider weight, bike geometry, tyre size, riding position and riding style all influence how a wheel feels in crosswinds.
Like any aerodynamic wheel, a 50mm depth rim will always be affected by crosswinds—you cannot overcome the laws of physics. Modern U-shaped rim profiles are designed to make these aerodynamic forces more predictable and manageable, but if maximum crosswind stability is your priority, a shallower 30–35mm wheel will naturally offer the most stable handling.
Regarding hub compatibility, our Ultra and Pro series use a DT Swiss-style ratchet system. While standard DT-style ratchets and freehub bodies may be compatible, manufacturing tolerances can vary slightly between different brands. Mixing components from different manufacturers may affect fit or performance.
For the best fit, reliability and long-term performance, we always recommend using replacement ratchets and freehub bodies supplied by the original hub manufacturer.

Thank you for the information, everything you said makes perfect sense. I was hoping that hub spare parts would be interchangeable and available locally but also understand that it can't be guaranteed that 3rd party party will work properly. I have all four of my current wheel sets built up with DT 240/180 hubs so it would be nice to have that flexibility. I'm going to look over the options a bit more. I'll reach out via WhatsApp with more specific questions if I plan to order. Thanks again!

I was hoping that hub spare parts would be interchangeable and available locally but also understand that it can't be guaranteed that 3rd party party will work properly. I have all four of my current wheel sets built up with DT 240/180 hubs so it would be nice to have that flexibility. I'm going to look over the options a bit more. I'll reach out via WhatsApp with more specific questions if I plan to order. Thanks again!
Hello,
If required, we can also build the VaporLite wheelset with DT Swiss 180, 240 or 350 hubs, paired with Pillar, Sapim CX-Ray or Alpina Hyperlight spokes.
Please bear in mind, however, that due to the high cost of DT Swiss hubs, these builds are considerably more expensive and therefore not as competitively priced as our standard builds.
The hubs we currently use have been selected because we consider them to offer comparable performance, reliability and durability, while providing significantly better overall value.

On the 50mm VaporLite II there was three different layups (the ones below)... will there be the same on these 60mm? What do you expect Race layup to weight?
Also these will be possible to order as 20F/24R(Carbon spokes) and 24F/24R(Steel/titanium) spoke configuration?
Extreme Ultralight: 350 g, Rider weight limit 120 kg, Impact test rating 110 J
Race Layup: 380 g, Rider weight limit 120 kg, Impact test rating 110 J
Heavy-Duty Layup: 410 g, Rider weight limit 130 kg, Impact test rating 120 J

Race Layup: 380 g, Rider weight limit 120 kg, Impact test rating 110 J
Heavy-Duty Layup: 410 g, Rider weight limit 130 kg, Impact test rating 120 J
Yes, we expect the 60mm to follow the same three layup options as the 50mm. Based on current projections, the weight difference should remain consistent at approximately +30g per rim between each layup, although this is still to be confirmed.
For reference, both the Extreme Ultralight and Race layups share the same rider weight limit and impact rating. The additional weight in the Race layup is primarily there to improve stability, particularly at higher speeds where extremely lightweight rims can become less composed.
There will be full compatibility across our hub range. Based on current information, this should include:
Carbon spoke hubs (1:1 lacing):
ZC-215Rc – 20F / 20R
ZC-235Rc – 20F / 20R
ZC-235Rc (2024) – 20F / 24R
ZC-245Rc – 24F / 24R
ZC-270Rc – 20F / 20R
ZC-288Rc – 20F / 20R
2:1 lacing options:
ZC-250Rc – 18F / 18R
THR Industries R2 – 21F / 24R
Steel / titanium spoke hubs (1:1 lacing):
ZC-240Rs – 24F / 24R
ZC-261Rs – 24F / 24R
So yes, a 20F / 24R configuration will be possible via the ZC-235Rc (2024) platform.

Good Day Members
Introducing the New Zen TiX Titanium Spoke Range
We’re pleased to introduce the new Zen TiX titanium alloy spoke range, available across selected Zen Carbon wheelsets.
Designed to bridge the gap between traditional stainless steel and carbon spokes, the Zen TiX range combines low weight, excellent fatigue resistance and improved vibration damping, making it an ideal choice for riders looking for a balance of performance, comfort and durability.
Unlike carbon spokes, titanium spokes can also be replaced individually if damaged, making them a practical option for riders covering high mileage or regularly riding on poor road surfaces.
The following technical specifications and performance figures are based on the manufacturer’s laboratory testing and engineering data.
Why Titanium?
Titanium alloy offers several advantages over conventional stainless steel:
• Approximately 60% the density of steel, reducing rotational weight.
• Naturally corrosion resistant.
• Excellent fatigue resistance for long service life.
• Lower elastic modulus than steel, helping absorb high-frequency road vibrations for improved comfort.
• Maintains stable spoke tension over extended use.
• Individual spokes can be replaced if required.
Engineering Features
Every Zen TiX spoke features:
• Precision titanium alloy construction.
• Arc-shaped spoke head to reduce stress concentrations.
• Bell-mouth head profile for improved load distribution within the hub flange.

The Zen TiX range has undergone manufacturer laboratory fatigue testing under repeated cyclic loading designed to simulate real-world riding conditions, including acceleration, braking and road impacts.
Recorded laboratory fatigue life:
• Zen TiX Pro — 19,166 cycles
• Zen TiX Titan — 25,295 cycles
• Zen TiX Aero — 49,525 cycles
• Zen TiX Aero SL — 48,646 cycles
According to the manufacturer’s laboratory testing, the Zen TiX Aero models achieved fatigue lives approximately 1.5–3 times greater than many conventional stainless steel spokes tested under the same conditions.
Tensile Strength
Ultimate tensile strength:
• Zen TiX Pro R & Pro E — 1120 MPa
• Zen TiX Titan — 1142 MPa
• Zen TiX Aero — 1120 MPa
• Zen TiX Aero SL — 1244 MPa
Wheel Building
The Zen TiX range has been developed specifically for modern high-performance wheelsets and is compatible with road, gravel and MTB applications.
Features include:
• Straight-pull design
• High spoke tension compatibility
• Thread-rolled spoke threads
• Arc-head design for improved fatigue resistance
• Premium wheel builds with steel, titanium or carbon spoke options
Available Wheel Builds
Zen TiX spokes will be available across all Zen Carbon wheelsets alongside:
• Pillar stainless steel
• Sapim CX-Ray (Inc Silver stainless steel now available)
• Alpina HyperLite
• Carbon spokes
giving riders another premium option depending on whether their priority is comfort, durability, weight or outright stiffness.
We’re excited to introduce titanium as a new premium spoke option within the Zen Carbon range available in black or titanium color.
For riders looking for a wheelset that combines comfort, durability, low weight and long-term reliability, the new Zen TiX range offers an exciting alternative to both traditional stainless steel and carbon spokes.

Zen Carbon Moulded Spoke Hole Rims – More Choice, More Customisation
We've started offering a new range of Moulded Spoke Hole (MR) rims across road, gravel, MTB and BMX applications.
Instead of drilling the spoke holes after the rim is moulded, the spoke holes are formed during the moulding process itself, helping maintain carbon fibre continuity around the nipple bed while opening up some very interesting weight possibilities.

What's everyone's thoughts on Ti Spokes? I've been waiting for these 60mm Vaporlite 2's to come to market but never really considered Ti spokes on a road wheelset. I have read the XMCS posts by Peter about their Ti spoked options but has anyone been using them?
For a very minor weight penalty over carbon spokes, they seem like a good option. With so many options these days I'm having trouble making a decision. This wheelset will be used mostly on a Cervelo S5 in place of the stock Reserve 64/57 wheelset which is awesomely aero and stable but a bit heavy. Sander has been a huge help but we didn't talk about Ti spokes.

Sander has been a huge help but we didn't talk about Ti spokes.
Personally, I probably wouldn’t choose the titanium-spoke option.
For example if the titanium and steel versions use 24 spokes front and rear with for example a 1:1 hub lacing, whereas the carbon version is 20/20 which is the normso it isn’t a completely like-for-like comparison. Even with fewer spokes, the carbon-spoke build could still be the stiffer wheel because carbon spokes are normally much wider and have very high axial stiffness.
I would say Ti would be more suited to MTB or Gravel.
Maybe someone here has a road Ti spoke Wheelset and can give there impressions
For general riding, titanium spokes may be absolutely fine, but on a deep 60mm wheelset fitted to an S5, I’d personally lean towards carbon spokes for performance or steel spokes for long-term reliability and easier replacement. Titanium seems to sit somewhere between the two: lighter than steel and possibly a little more compliant, but with less long-term user feedback.
Rider weight and power are also worth considering. Everyone talks about wheel stiffness, but how noticeable it is can be quite subjective.
Why not consider carbon spokes?
I do not find carbons spoke wheel give a harsh ride anymore.
We’re no longer riding 23mm tyres on narrow rims at 100psi. With a 25mm internal rim, 30 or 32mm tyres and sensible pressures—I run around 52/56psi—the tyres provide most of the comfort.
-
Thanks for the input as always Sander 2177. Everything you mentioned aligns with my less informed thoughts as well about Ti Spokes. Maybe I'll give them a try on a gravel wheelset down the road.
I'm leaning towards the Race Layup, Ultra Series ZC235RC hubs, laced with 3.2mm spokes and hidden nipples. Or maybe 3.1mm spokes and no holes in the rim bed. I'm about 75kg and don't mid a ride on the stiffer side. For the sake of 60g additional weight I don't think the ultra-light layup is for me given our rough roads.

No worries mate, you’re not less well informed—the information is out there.
I’ve been looking at these quite a bit myself. Zen also now offer 4.0mm and 5.2mm hidden-nipple carbon spokes, as well as the lighter ZC215Rc hub.
What’s interesting is that the 4.0mm and 5.2mm hidden spokes sit roughly in the middle of the 3.2mm hidden and the 3.25/3.95/4.5/5.1mm regular spokes in terms of their technical specification.
Weight-wise:
* 3.1mm regular = 2.1g (including nipple)
* 3.2mm hidden = 2.1g (including nipple)
* 4.0mm & 5.2mm hidden = 2.7g
* 3.25mm, 3.95mm, 4.5mm & 5.1mm regular = 3.5g
So if you’re looking for a bit of a balance and have any concerns about stiffness, I’d probably be looking at the 4.0mm hidden spokes. You only give up around 24g compared to the 3.2mm hidden build, but on paper they look like a nice compromise between weight and stiffness. It’s certainly an option worth considering.
-
I'm also considering these, but in really interested in the TiX Aero spokes option. Service wide they will probably be better, especially if one buys a few spare spokes. They will not be as stiff, and Zen first told me CX-RAY is better for road wheelset, but then i told them that im only 69kg weight, and they said that they will work fine for me.
As i have understood Ti stretches kind a bit more than steel.
So im really considering Ti as a serious option... I got a little bit off about carbon spokes after i saw Pandapodium test of Ti polymer spokes on youtube. This is what kind of turned me back to either CX-RAY, Alpina hyperlite or these new TiX Aero spokes.

Good day, CHINERTOWN members,
Just a quick update regarding hub options.
While most of our wheelsets are typically built around our own lightweight hubs or H-Works hubs, we can also build custom wheelsets using a wide range of premium hubs to suit different priorities, whether that’s low weight, durability, engagement or serviceability.
Current hub options include:
* DT Swiss 180 – Premium ceramic-bearing hubset. Lightweight, reliable and easy to service, making it a popular choice for premium road builds.
* DT Swiss 240 – Excellent balance of weight, durability and value. One of the benchmark hubs for performance road and gravel wheelsets.
* DT Swiss 350 – Slightly heavier than the 240 but renowned for exceptional reliability and easy maintenance. A great option for high-mileage riders.
* Carbon-Ti – Ultra-lightweight Italian-made hubs featuring titanium and carbon construction. An excellent choice for riders chasing the lowest possible wheelset weights.
* Extralite – Among the lightest production hubs available. Precision CNC machined in Italy and ideal for premium lightweight builds.
* Tune – German-made lightweight hubs with a long history in weight-conscious custom wheel builds, combining low weight with proven performance.
* Chris King – Manufactured in the USA and widely regarded for outstanding machining quality, durability and the distinctive RingDrive engagement system. Built to last for decades with excellent serviceability.
* White Industries – Another premium USA manufacturer, known for beautifully machined hubs, smooth bearings and exceptional long-term reliability.
If anyone has a preferred hub that isn’t listed above, feel free to ask. We can often source additional premium hubs for custom builds depending on availability.
As always, the best hub depends on your priorities—whether that’s achieving the lowest possible weight, maximum durability, fast engagement, ease of servicing or simply a particular aesthetic.
Happy to answer any question so please get in touch with us using the contact information below.

Do you know (or maybe Zen can answer here) the thickness and cross-sectional profile of the 4.0mm spokes? I'm guessing at the round ends they are Ø2.2mm so similar stiffness to the other "heavy" carbon spokes.

Zen Carbon – Spoke Options
One of the questions we’re asked most is why we offer so many spoke options.
The answer is simple: there is no single “best” spoke. Every spoke represents a compromise between weight, stiffness, fatigue life, aerodynamics, durability and cost.
Rather than forcing every customer into one specification, we offer a wide range of spoke options so wheelsets can be built around the rider’s priorities.

Hello Sir
The lightest 65 mm road rim we currently offer that is suitable for yourself is our 25 mm internal / 32.4 mm external profile @425g
For your 92 kg system weight, we would recommend the 425 g Superlight layup, which has a 100–110 kg system weight limit. This is the lightest suitable option in our 65 mm range. Next is 135kg limit at 495g
Alternatively, we have our new VaporLite rim. Although it is only available in a 60 mm depth, it offers a higher 120 kg system weight limit while being significantly lighter.
The available VaporLite layups are:
* Ultra – 385 g per rim, 120 kg system weight limit
* Race – 415 g per rim, 120 kg system weight limit
* Heavy Duty – 435 g per rim, 130 kg system weight limit
If you’re happy to consider a 60 mm depth instead of 65 mm, the new VaporLite would be our recommendation as it offers an excellent combination of low weight, strength and aerodynamic performance.
If you would like further information, a complete wheelset weight estimate, or a quotation, please don’t hesitate to contact us using the details below. We’d be happy to help configure the most suitable wheelset for your riding requirements.

if i was using a 2:1 lacing on THR R2 hubs - could i get away with using the lightest 65mm carbon rim (the 385g version) having extra spoke count and and taller hub flange on a rear wheel or is the 90 Kg weight limit pretty much it regardless of how the wheel is laced?
or i guess i just need to quit eating cake!

;D Sir
The 90 kg rider/system weight limit is for the rim itself, regardless of the lacing pattern. We would not recommend using a 2:1 hub with this particular 385 g rim. For this rim, we would build it with a 1:1 spoke pattern hub.
These 90 kg rims are designed primarily for lighter riders and good road surfaces. We also recommend leaving a reasonable margin below the maximum weight limit, especially if you regularly ride rough or poorly maintained roads.
As I mentioned before, our latest VaporLite II 60 mm rim is a much more advanced option. It has a 120 kg weight limit and uses an updated blend of T800, T1100 and MJ carbon fibres, making it significantly stronger while remaining very light.
Some example builds are:
* THR R2 hub (285 g), 3.95 mm spokes: 1,212.5 g
* THR R2 hub, 4 mm hidden carbon spokes: 1,176.5 g
* ZC235Rc hub (235 g), 20/20 spokes, 3.95 mm spokes: 1,145 g
* ZC235Rc hub, 4 mm hidden carbon spokes: 1,113 g
In our opinion, the VaporLite II is the better choice if you’re looking for the lightest wheelset without compromising strength and durability.

Coming Soon – VaporLite II 60 mm
Estimated wheelset weights VaporLite Ultra:
Carbon Spokes Bladed 3.1mm (Optional Spoke widths 3.25 / 4.5 / 5.1 & 5.9mm. Hidden Spoke Nipples 3.2 & 5.2mm all available upon Request)
1,069 g ±30 g – Paired with our new ZC-215Rc hub (215 g), replacing our previous lightest hub. ZC235Rc 20F 20R
1,089 g ±30 g – ZC235Rc 2024 (235 g, 20F/24R).
1,099 g ±30 g – ZC245RC (245 g, 24F 24R).
I think something is missing from these weight calculations. ZC235Rc 2024 is 20g heavier than ZC-215Rc. But the complete wheels weights only increases 20g from 1,069 to 1,089. It doesn't seem to account for the weight of four extra spokes and nipples in the rear wheel. (or subtract the material loss in the rim of four extra holes).

HUB Update
Hi everyone, we’ve got an update on our hubs.
Our previous lightest hub platform, the ZC235Rc (20h front and rear), has been used across a wide range of our builds, including the VaporLite range of wheelsets.
We now have an updated version of this platform — the ZC215Rc — a newly optimised 20h front and rear hub with 20g shaved off, bringing the weight down to just 215g per set! :D
Alongside this, we’re also introducing a new addition to the range: the ZC235Rc 2024, now available in a 20h front and 24h rear configuration, weighing 235g per set.
As an example, the new VaporLite II will now achieve a claimed weight of 999g utilisimg the ZC215Rc , down from 1019g.
These hubs are now available across our full rim range. :D
Do the new hubs use same bearings as before or lighter, less load restistance/durable bearing?
-
Do the new hubs use same bearings as before or lighter, less load restistance/durable bearing?
Hi Sir,
Thanks for your question.
All of the new hubs use the same bearing specifications as before. The weight reduction has not come from using smaller or lighter bearings. Instead, it has been achieved through additional engineering, material optimisation and hub shell redesign while maintaining the same bearing sizes.
Regarding your question about “less load resistance”, could you clarify what you mean? Are you referring to maximum rider weight, bearing load capacity, or rolling resistance?
As for bearing durability, it’s important to remember that bearings are consumable components. Their lifespan depends on many factors, including:
* Rider weight
* Riding style (racing vs. recreational riding)
* Road and weather conditions
* Maintenance and cleaning
* Mileage and frequency of use
For example, a rider who races regularly in wet conditions may need to replace bearings much sooner than someone who rides once a week in dry weather. Because of these variables, it’s not possible to quote a fixed bearing lifespan.
Please see the bearing specification table below for the bearings used in each hub model.
-
I mean load capacity. But if all the listed hubs use the same bearings, there will be no difference regarding this point.

Hello Everyone,
We'd like to let members know that our new website is now live:
www.zencarbonbike.com
The website is still being updated and expanded, so some content and products are still being added. It currently features a selection of our most popular pre-configured wheelsets, allowing customers to view specifications and pricing more easily.
For bespoke wheel builds, custom specifications, or personalised recommendations, we still encourage customers to contact us directly, as many of our available options are not yet listed on the website.
Thank you for your continued support and feedback as we continue to develop the site.

@ZenCarbonBike do you have any picture of any of your wheels built with silver hubs and CX-Ray silver spokes ?
I am currently looking at wheelsets for my new QuickPro ER:One and I think that silver hubs/spokes would perfectly match the raw carbon look of the frame, especially with that kind of quickpro decal on the frame
(https://raceit.cc/cdn/shop/files/QUICK_PRO_ER_ONE_NIGHT_BLACK.png?v=1765823847&width=1500)
-
Simple answer to his question
He needs thicker carbon spokes
Or go
20/24 or 24/24 spokes with 3.1mm
Or
20/24 or 24/24 spokes at 3.95mm or 5.1mm as they are about 40% stuffer
And will then give him a stuffer Wheelset
Is adding spokes count (20->24) superior for stiffness against going for stronger spokes (while maintaining 20 spokes count)?
When should your new Vaporlite II 60mm 3,95 carbon spokes wheelset should arrive? Very interested in your thoughts and experiences.

Hello Everyone,
We'd like to let members know that our new website is now live:
www.zencarbonbike.com
The website is still being updated and expanded, so some content and products are still being added. It currently features a selection of our most popular pre-configured wheelsets, allowing customers to view specifications and pricing more easily.
For bespoke wheel builds, custom specifications, or personalised recommendations, we still encourage customers to contact us directly, as many of our available options are not yet listed on the website.
Thank you for your continued support and feedback as we continue to develop the site.
Crankset is very interesting ! Have you thought about doing an 8 Bolt / Sram interface?

Here’s a recent bespoke customer build that left us yesterday.
The customer wanted something a little different from our standard finishes, choosing a split UD matte / UD gloss carbon finish, combined with silver permanent ZEN decals.
The finished wheelset came out at 1,244g.
Wheelset Specification
Rims
• 45mm front / 50mm rear
• U-shaped aerodynamic profile
• 25mm internal width
• 32mm external width at the bead
• 34mm maximum external width
• Hooked rim design
• Spoke-bed access holes
• Drainage / pressure-relief holes
Custom Finish
• Mixed UD matte / UD gloss carbon finish
• 3 × silver permanent ZEN decals per side
Hubs & Spokes
• H-Works SR270 hubs
• Silver finish
• Steel bearings
• 36T ratchet system
• Shimano HG freehub
• Spare SRAM XDR freehub included
• 3.1mm superlight bladed carbon spokes
• 20 spokes front / 20 rear
Finished weight: 1,244g
For comparison, this configuration using our lightest UD paint-free matte finish was estimated at approximately 1,170g ±30g.
The customer’s special patterned/painted finish increased the estimated wheelset weight to approximately 1,230g ±30g, with the completed wheelset weighing 1,244g.

Hello everyone,
Additionally
Below is a list of our current carbon spoke hub options, including front and rear hub weights and available lacing patterns.
Please note that certain front and rear hub configurations can be mixed across different hub models to achieve the weight and spoke configuration you require. For example, the 18H 2:1 front hub from the ZC250RC hubset can be paired with the ZC215RC rear hub, resulting in a combined hubset weight of approximately 220.8g.
Most hubs are available in both black and silver, although some models are available in black only.
If you would like more information on the available options, compatibility, or custom configurations, please contact us using the details below. We would be happy to help find the best setup for your build.
Have a good day

Is the RC235 2024 not a mix of RC235 front hub and RC245 rear hub? The weights a different. So RC235 2024 is a own, separat development?

Hello
Thanks for the question.
The ZC235RC 2024 is not simply a ZC235 front hub paired with a ZC245 rear hub. It is a separate revision developed specifically for the 20/24H configuration.
While the total hub weight remains 235g, the weight distribution is different:
ZC235RC: Front 76.4g / Rear 158.6g
ZC235RC 2024: Front 72.9g / Rear 162.1g
Most of the difference comes from the hub shell design .
The 2024 version uses a lighter front shell and a slightly heavier rear shell to suit the 20/24H layout and improve stiffness and load distribution.
So although the overall weight is the same, the ZC235RC 2024 should be considered a dedicated 20/24H hubset rather than a mix of existing ZC235RC and ZC245RC components.

Seeing the great feedback on this thread, I've decided to order a pair of Zen Carbon Wheels from Zara. So far the ordering experience has been great. Zara has been very responsive to my queries.
This is the configuration I went with:
* Rims: 25mm IW, 50mm depth, UXL weight 380g, UD paintless gloss finish
* Hubs: H-Works SR261, steel bearings, weight 269g
* Spokes: Sapim CX Ray, weight 4.9 x 48
Total expected weight: 1264.2g
Could've gone lighter with the SUXL rim at 350g and carbon spokes, but I was worried about reliability being a heavier rider at 85kg. Zara shared the lead time is about 4-5 weeks so I'm looking forward to when these ship to the West Coast here in the US.

Hi, I'd like to share my experience with buying a wheelset from ZEN. I'm very happy with the purchase so far. Zara was amazing to communicate with and helped me build out the specs I was looking for. Amazing customer experience, I must say.
I ordered everything over WhatsApp, and from the time of payment (PayPal) to when I received the wheels in the Czech Republic, it took about 6 weeks.
Specs I went for:
(The specs are inspired by the No.6 52/58 wheelset.)
- Front: 50mm depth, 25mm inner, 32mm external, 350g
- Rear: 55mm depth, 24mm inner, 31mm external, 450g
- Both hooked, tubeless-ready, with drain holes
- UD glossy finish
- Load limitation: 120kg
Hub:
- ZC235RC
- 36T ratchet system
- Center Lock
- Ceramic bearings
- Black color
- 20/20 holes
- HG / XDR / N3W / MSR freehub
Carbon Spokes:
- Front: 3.25mm width
- Rear: 5.1mm width
Weight:
1173 +/- 30g
(Actual weight was 1201g, see photo.)
Overall, I'm very happy with the purchase. Although I've only done one ride on the wheelset so far, about 80km, it's too soon to say how well they will hold up. However, my first impressions are that the wheelset is very stiff, and it feels really cool and fast to ride out of the saddle. Based on this i'd recommend the ZEN wheels.

Zara, do you have in pipeline 25 mm IW rim with lower depth (like 40 mm)? Preferably paired with steel spokes.
Could anyone also tell me if they’ve had any problems with these hubs? I’m interested in the after-sales service for customers in Europe (mainly the availability of spare parts for the hubs).

Sorry, I wasn't precise. I meant the 40 mm variant of VaporLite II rim.

Hello I’m afraid not only black or silver.
Most of our hub offering are either black or silver.
The only hub available in multiple color options like TI, green, purple, blue etc is the THR Industries R2 hub

Received, installed and went on a 80km ride this morning on my new 60mm wheels; I am not a fast rider so aero gains are hard to evaluate for me but the upgrade on the feel side from my 50mm csc wheels is significant. The ride quality is so much better, even though I went from 40mm (Hutchinson caracal) to 32mm tires (Michelin power cup, 35mm mounted). The road buzz is significantly reduced.

Just an update on my Zen wheelset. Had bike serviced and they checked on the SR270 hubs and they said they looked incredible. Zero dust and needed nothing but to be closed back up.
Wheels have been incredible so far! Closing in on 3000 miles on them.

I haven't seen a lot of discussion on here about Zen carbon cranks. Specifically, BC03 cranks with 24mm Titanium spindle that come out to 300g. These chinese cranks (Cybrei, Elilee, Leese, Bigrock, etc) all look very similar so I suspect they're made from an open mould design and probably in the same factory. But searching around I couldn't find any that are 300g. Only Zen seems to be offering these and all the other brands seem to bottom out at 310g for this design. Anyways, I've gone ahead and order a pair. Was quoted $290 shipped to the US. Will report back once I receive them.
