Hello,
for the triathletes: Are there recommendations for Chinese carbon plate running shoes? Which shoes are good value, which ones are best for short versus long distance, ...?

There is another TT frameset from Tantan/Seraph called T928
https://www.seraphbikes.com/UDH-Carbon-Time-Trial-Bicycle-Frame-TT928-TT-Bike-Frame-Aero-Triathlon-Bike-Frameset-High-Quality-Disc-Brake-Max-Tire-70030C-p6901419.html

To me, the geometry and STA look good. Also, this frame has a UDH dropout and a good looking handlebar, even though I do not know how adjustable this bar will be.
What do the experienced triathletes and TT bike builders in the community think about the TT 928?

Thanks a lot to everyone.
So there is a clear vote: Shimano remains the best option for bsa.

Are there any opinions and experiences for the best value t47 bottom bracket?

Does anyone know if the Magene H613 can be used for swimming? On their web page, they state it is IPX7 - does that mean you can take it to the water (officially IPX7 is waterproof for up to 1m for 30min).

Hello to the triathlon experts, I am currently planning my first triathlon build and have some questions about the ICAN TT 017 frameset:
It appears that it is currently more or less the only frame with a UDH bottom bracket.

So questions No1:
Is it possible to build this frame with a 1 x 13 SRAM setup?
That would mean a
SRAM Rival AXS XPLR E1 13 rear derailleur
2 sets of blobs
a 10-46 cassette (yes I now that 46 is huge for triathlon, but we have plenty of short hills with about 10% around, so the 46 could save me while the rest of the cassette is mostly the some as the 12s 10-36
and a KMC go waxed chain (does this work with 13s?)

And questions No2:
I do not really like the handlebar extensions. Could I simply change those extensions against any other 22 mm carbon extension, like e.g.

Thanks for you help and feedback!

It is the 12s 105 di2 groupset that I got, and it included the brake calipers.
With the Magene PES 515 crankset, the ZTTO steel cassette, an KMC waxed chain and some rotors (I prefer the MT-800 as I don't like experimenting with brakes, but there might be cheaper non-Shimano solutions) you have a complete groupset which is almost the same weight as an ultegra di2 groupset yet includes a spider powermeter and is still cheaper compared to a complete ultegra groupset.
I do not have any experience with Ltwoo or other Chinese group sets, but from reading in this forum it appears to me that shimano in 2025 is still the more reliable option.
Warranty is definitely a disadvantage when you get your parts from AliExpress. I never needed the warranty so far, but I would guess that you do not get a replacement in case of an early failure, so that is what you have to accept (and what actually makes not only the group sets but also the frame sets cheaper when you buy them directly from China).

Does anybody know if this frame is available without this strange air intake? Besides this strange plastic part, the frame looks quite good to me with reasonable geometry, UDH hanger and T47 BB.
And does anyone know the weight of the frameset in different (larger) sizes?
