TT-X71 Build
« on: July 17, 2026, 09:14:23 AM »
Hello everyone,

since I customized my Wilier Cento10SL Rim to all my needs I really enjoyed working on my bike.

So as a next project for the next months I am looking to build a nice roadbike on the tt-x71 frame.

As this is my first bike build I could use some advice.

As a vision I want the bike to look like the Factor Ostro Vam 2026.
I want it to be glossy black, without decals (as I will add them later).

This means I also a need glossy black wheelset. On my other bikes I ride Elitewheels and I am really happy with them. It's just not the color I want for the new bike.

For the groupset I want to try a chinese eletrical groupset - the LTwoo ER7.

My goal is to build it as price efficient as possible.

When it comes to pricing it looks like this so far:
Frame (need to find out who to contact for black glossy without logo) ~750 €?
LTwoo ER7 (https://de.aliexpress.com/item/1005010071784200.html) 470,69€ + 42,12€ shipping
Wheelset didnt find a glossy black yet that costs around as much as Elitewheels
Brake discs still need to find
Inner Tubes I have a small stock of RideNow TPU
Tires I have Conti GP 5000 in 30mm
Bar Tape I have black SRAM bar tape
Bottle Cages need new ones
Powermeter I currently use a Magene PES 515 with 165mm cranks on my mechanical Shimano Ultegra at the Wilier. I want to keep using it. Is it compatible with the groupset i linked? That groupset already includes the cranks and chainrings, as well as the cassette 12s 11-32 and a 12s chain.

If you need any other information, feel free to ask.
Of course I am gonna keep this thread updated with the ordering process and the building itself.

I am located in Germany if that matters.
I also tried getting a used Shimano 105 Di2 grouset, but they are really expensive here (or its scam).
Also I want to give the chines groupsets a chance (unless you tell me to absolutely not do this).

Thank you in advance for reading and putting thoughts on this.

the ER7 at this price really isnt a good deal. I would do Shimano 105 di2 mini group from Aliexpress. if you buy when there's a 50-75 eur coupon, you can get it at a price that's higher for sure, but not much higher, and ltwoo really is hit and miss. to be fair, they are improving, and i installed 4 of the v1 groups. but i wouldnt spend that kind of money of an ltwoo group myself, fwiw.
