My Velobuild TT in size M is finished and rides incredibly well – it's lightning fast!

The color is exposed carbon with a glossy clear coat and custom decals (which Velobuild produced for an additional fee and applied under the clear coat).

TRP brakes (with SRAM Blips)
SRAM XPLR rear derailleur (54/10-36)
SRAM Rival E1 Powermeter
ELITE EDGE 2.0 (65mm)
12cm of Spacers

Custom-designed toolbox
AeroCovers on the spacers
BTA for the Velobuild handlebars
All parts are 3D printed.

Can you also customize the toolbox for an S-frame?

The problems are with the stem of the TT023 frame. Your stem is completely different.

Is there a new alloy stem available? Do you have a link or photo for it?

Went out for first test ride...
Handlebar slipped (common issue) and clipped brake hoses.

Talked to Chris from Velobuild and told me to get shorter screws (12mm including bold head instead of the ones that came with the bike which are 20mm including bolt head, 15mm without bolt head) so stem can clamp handlebar better.

Has anyone tried this or how have you prevented handelbar from turning?

Will try getting the screws and will update

I used a lot of grip paste and tightened the screws meticulously and evenly (4.5 Nm, I think).
After that, I had no more problems.

Out of interest: how can shorter screws help it to fit better?

Do you think this build can work ?
As I previously mentionned, i want a double crankset + manual shifters rather than electronic (budget build)

i'm pretty sure of everything, but i don't understand why all the crankset are specified "BB wide 68/70mm", but the velobuild need a 86.5mm

I can't recommend a mechanical gear shift in this frame.
The bends are much too extreme. I had to heat the brake line slightly, especially on the handlebars and stem, so that it could be bent.

I can't imagine that the shifting performance won't suffer as a result.

Besides, you won't have any gears on the basebar, which can be a real disadvantage depending on the route.
You're riding with a double front, so you want small gear jumps. Are you also prepared to stop shifting on climbs because you're reaching for the base bar?

A used AXs rear derailleur costs €80-100. The front derailleur costs €60-80. Wireless blips cost €75 per pair. That's well within your budget.
Oh, I forgot the batteries: €25-40 each.

Following up after replacing the stock stem with the Vision Metron Snakebite system. It’s been great so far, pictures of how I routed the cables attached (you need spacers and I cut them). Thanks to Nikko for his help.

On frame box from Matt Golt (thank you). BTA system, Blip mounts ect are from https://www.wattworx3d.com/

Overall happy with it so far - they did send me a replacement stem as well, just don’t trust it honestly.

Great work!
Good to know that you don't need the original stem. It's a known source of problems, and the cable routing isn't that easy either.

Why did you do the conversion?

I am very interested by this frame for my upcoming long distance triathlon, I've read in the thread that I can contact chris from velobuild, anyone got his contact?
How much overall can I expect to pay for a full build?

I paid 2000€ for complete Bike with new wheelset and the other components second Hand. (50mm Carbon Wheelset, 2 x 12 SRAM axs, riderever triva brakes)

Hi, I'm looking at getting the VB-R-368 which looks to have the same seatpost as the TT-023. Can someone with this frame show what the adjustable seat clamp looks like? Wondering how much adjustment there is fore-aft.

Look Here at "packing list" and picture "j" https://www.velobuildmall.com/products/vb-tt-023-new-t47-carbon-fiber-time-trial-frame-set-disc-integrated-cables

Or you need specific measurements?
