I think the chance that they're both doing the same steerer as the original product, including the kevlar braid, but from two different factories, is close to zero.

They're almost certainly using the same factory for the fork at the very least.  Frame may indeed be different factories. I think this is the same 'Taiwanese' (probably nothing to do with Taiwan at this point) clone seller with loads of shopfronts on AliExpress. The quality of their frames is usually significantly higher than TanTan.

Just curious if you have actually compared the two side by side ?

Got my D50CU-28 T1100 in the Mail. Wheels look great, packaging is very good and overall quality seems to match expectations.

One caveat are the actual rim measurments. Actual measurments are 22mm internal and 29mm external instead of 21.4mm internal, 29,2mm external.
With the wider internal and narrower external width a 28mm gp5000 s tr measures 29mm and sits flush with the rim profile, so no rule of 105% to achieve here, if your don't want to have a 25mm tyre, which most of us certainly will not want. So in some way the rim profile is neither here nor there, neither fit for narrow nor really fit for wide tyres. I will get on with it, but this difference to the advertised measurments is the worst difference you can have in a rim profile. Both rims measure the same btw, so i don't think this is a unit variation problem.

Measurements done with a digital caliper and at multiple locations.

I don't think it's going to make much of a difference but it's always good to know and feedback. :-) I think it's sort of expected if you buy parts from China although I think Peter held himself to a different standard.

I order a 52mm headset bearing once and the seller send me a 51mm, and claim that it was variance due to manufacturing... that was a WTF moment since all the bearings I had bought previously was precise to 0.1mm.

Anyway, looking forward to the rims from Peter. Still thinking about the Frameset though...

This thing's price gets you some pretty serious used hardware. TCL SLs, Ultimate CF SLXs etc. With actual resale and some semblance of warranty support.

Do wish they are monitoring this web forum. Frame looks nice but no way I would pay more than $800 for it...

Only reason I opted for UD glossy is that my last SPCycle frameset had so-so paint. My other UD glossy frameset seemed to fare better from regular ride wear. I attached a photo they sent me with the frame on the scale.

Anybody has any feedbacks about this ? Seems lighter than TT-X68 ..

LC at 870g, TanTan at 1096g. The TT-X68 is 836g.

Isn't TanTan = TT-X68 ? Do I have to specifically mention the weight or is it assumed ?

Now that is crappy, they literally just glued that shit on. It doesn't even fit well

Isn't every carbon "glued on" literally piece by piece... quite weird and strangely interesting... ... they went out of their way to have a "aero" design... including front fork as well.

Do you think the 6903 bearings can really lower the rolling resistance ? I am not sure, DT Swiss uses same 6802 and 15267 on their hubs. At least so far we haven't any client saying our hubs with high rolling resistance or anything bad. Anyway we use good bearings, maybe just different sizes with others'.

Thanks. I'll msg you to confirm the details, price and order.
