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?

T700 is the backbone of carbon fiber bike stuff (both rims and frames). T800 is more expensive, then T1000, T1100, then M40X. So, what do you get for the extra cost?
Stiffness goes up, and weight goes down.
However, with extra stiffness comes fragility. A rim that's full T1100, for eg, would be too fragile, and wouldn't pass impact resistance tests. Which is why, i assume, some of the highest end frames (sworks, for eg) have a reputation of being very fragile (think car travel where you throw the bike in the boot to find you cracked it).
And so, T700 is the backbone, and the others shave weight and add stiffness.

Having rebuilt my supersix rim w 50mm tubulars, the whole bike weighs 6kg, it's great fun to ride a light bike. It's snappy, you want to surge up every slope.
So, given  we're talking OEM pricing / providers, i'd strongly suggest you spend (at least a little bit) extra for the lighter version of a given rim. Ofc, some sellers make ultra light rims for ultra light people, this is niche, i'm not talking about that.
Peter, for eg, sells a standard T700 version, a light version (mix of 700 & 800), and is working on a version that includes T1100 as well.
Idk the price difference from 800 to 1100, but i know i only ever bought the 800 version because every time you accelerate, you do feel the weight of the wheels (that energy is stored and you'll roll longer unless you brake, but it still is harder to accelerate, and it feels nicer to have a snappy bike).
Also, from a resale standpoint, you'll have an easier time selling at a good price a set that's light
Fast on the flat. And nowhere else.

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

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

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

Correct. It can't be full T1100, otherwise it would be too fragile.

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

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.

We would release two new road disc frames, but biggest sizes on both framesets is about 54cm for now, and we are still having someone testing them.

I don't think we would offer groupset, it is not cost-effective to buy Shimano or Sram from China, and we don't want to be reseller on Ltwoo or Wheeltop, and their quality...

TanTan makes good quality frames, and we have been cooperating with each other on some points. Will try our best to offer best value frameset and wheels package.

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

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

Received my wheels from Peter last week. Could not try them yet as my frame hasn’t arrived yet. Did check them out and they look really good.

For this price point also seriously impressed with the weight. Just a few grams above 1400g. That is quite impressive for a 50mm deep set, 28mm iw and 36mm ew.

Communicating etc with Peter is top notch. Happy purchase so far ^^.

Hi Peter, I'm in the market for a new frame, could you pm me more details on this and a price, do you do paint designs?

Sorry. I was planning to upload our 2nd frameset here, but not sure why I wasn't able to upload pictures again.

Could you send me an email and I will reply you with details?

Thank you so much.

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