it will depend on spokes and hubs.
My friend crashed one of Peter's wheels, and broke 4 steel (Pillar wing 20) spokes. I didn't have enough spares to repair it (from memory, the wheelset uses 3 different lengths, so the moment you break more than 1, the probability you have inventory goes down dramatically), and good luck sourcing these spokes outside of china at a good price.

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

Knowing you can mix and match safely is above my pay grade (and I doubt manufacturers would agree with you). I wouldn't want to pretend I understand the physics of spokes and if my friend is going at 100kmh downhill, I wouldn't want to worry whether the melting pot of spokes from the bin is going to hold or not.
Where do you source your spokes? Are there useful resources I missed? My googling skills led me nowhere back then.
Fast on the flat. And nowhere else.

Guys. We are going to release our T1100 rims next week. The rim in attached pictures is D50CU-33 T1100 rim UD paintless finish, under 390g/piece.

We are going to build these rims with carbon spokes and our hubs. The promotion price for below combo wheels would be 635 USD/pair excluding shipping, lasts Dec 24 :
D50CU-33 T1100 rims 21/21H UD paintless
Carbon Speed hubs 54T rachets TPI ceramic bearings center lock straight pull for 100*12/142*12 with Shimano HG driver
Carbon spokes with nipples

The weight for this combo wheelset would be around 1245g/pair

And we are doing 20/20H version lighter hubs which won't be released until 2025, it will save another 40-45g on the wheels by then.

Peter, are you guys gonna have a similar version for MTB wheels?

I'm not saying you should just put any old spoke into your friends wheel. I'm saying they are exactly the same.

Sapim in Belgium came up with the CX-Ray spoke by drawing a round spoke to a cross section of 0.9mm x 2.2mm. Everyone else subsequently came up with an exact copy of that design. The cross section doesn't differ with any of the other ones because this is exactly the biggest aero spoke that will still fit through conventional holes in any given hub.

So all of the spokes I mentioned are steel spokes with the same cross section. Therefore they have the same elasticity, regardless of differences in the grade of the steel (Sapim, I guess, might use higher grade steel than CN spokes. But that's really only a guess). There might be the tiniest differences in the length of the bladed section but if you'd bring a wheel to me I wouldn't hesitate replacing a Pillar Wing 20 with a CX-Ray. There will be no difference, I assure you.

Being in Europe, I get my spokes from wheel-parts.shop in the Netherlands. I never really bother replacing Wing20s like for like (unless somebody demands it) since there is a distributor in Germany getting them from Taiwan, but they end up being more expensive than Sapim. I happily buy chinese wheelsets with Wing20s however, as I don't think the up in price to upgrade to CX-Rays does anything. If I want to go cheap, I buy CN spokes which can be had in Germany. The threads on these are sometimes not rolled that well which is annoying when building wheels.

Are you also offering Wheels with Dynamo?

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

I am also looking for wheels right now, and depending on the design, these may also interest me. Do you have a rim weight for the 65mm deep T1100 rims?

Regarding hubs, do you build with 0011 / THR Industries RX hubs or R3 road hubs? With CX-Rays Super or Alpina Hyperlight Aero spokes, these appear to be built wheels lighter than most carbon-spoked wheels.
I might be interested in the lighter hubs version 65mm deep. Do you know yet roughly in which part of 2025 it might be?

I don't think we want to do the T1100 version on D65CU-33 rims for now, it is too deep and we need to assess the possibilities like balance between strength, stiffness and light weight. We will try to do T1100 and test on D65CU-33, if everything is okay, then we will release them too.

Wing 20's are .3 mm thicker and shallower than aerolite I and cx ray. Wing 20 will be measurably slower aerodynamically. Aero 494 are completely different and much closer to dt Aero II than any of these other ones so I'm going to assume you meant the 424 which are very similar to cx-ray and aerolite I

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

Hi everyone,

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

T1100 is T300 faster than T800

Any plans on releasing new frames gravel or road?

Also possibly ship groupsets together with the packaging?

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

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