It's crazy how variable peoples fits are... Tobi is 194cm and says the fit is great, muringuets is 12cm shorter and feels like the reach is too short??? Interested to hear some elaboration on this.

Indeed fits can be very unique.
For context: i'm also only like 180cm probably. And would also like more reach.
But my bikefitter told me (for my road bike), that I have short legs and longer torso. My seatpost is as low is it can go

The frame box is my custom design. The other box available for this frame won't fit these types of aero bottles.

Do you think that this would also fit for normal round bottles? the previous design posted here was specifically for the aero-bottles..
This one seems to also fit normal bottles.


And by the way.. I can confirm the bar slipping fear will never go away... I have now more than 3500km on the bike but it never happened again (the new alloy stem is definely better btw)

Hey everyone,

Does anyone know the exact torque specs for the screws on the aluminum front stemm ? And the torque specs for the extensions? And for the spacer towers? thx.... My Frame Arrived Yesterday

Based on my own experience:
I used 4-5NM for the stem crews (clamping the handlebar), 4-5NM for the spacer towers, extension to baseplate just untill fixed (probaly also around 4NM but don't know for sure).
The clamping of the massive alloy stem onto the steerer tube needed around 8NM of torque to grip the steerer enough. I am thinking you need the high force to bent the clamping of a solid alloy stem (because the stem still slips onto the steerer otherwise).
I would advise increasing the torque with increments of 1NM just until the bars don't spin anymore

I also got the new alloy stem
Everything fits great, routing is much easier than the previous carbon one 😛

But how many NM to put on the stem bolt (for clamping the steerer tube)?
I seems it needs lots of torque to not slip?

Mmmm I don´t remember...I just measured the length of the brake lever and cut the handlebar as short as I could following the instructions.
Sorry that is not so helpful.

But I hear that you did cut them? That's the only thing I needed to hear
I will also be cutting them for a next fit.. but didn't know if it would be safe But apparently yes

Sorry I made a mistake attaching the files in my previous post

Those risers looks amazing.

Another question: did you cut the basebar handles a bit shorter? they look not as long as others?
Does anyone have experience with cutting these bars? would it be safe to cut them a bit shorter? I think that would improve handeling (especially using RideRever Trivia brakes, that only extend outwards)

My carbon stem gave way at such tightening torques.
I received the Alloy stem from Chris super fast within a few days, and with carbon paste it is tightened to 4nm.
At 2nm, it was already impossible to get any movement out of it at full force, so the fit is perfect.

Can you show an image of the new Alloy stem?
I also broke my top piece (of the carbon stem) two times.. third one I received, it works fine.. but now I still keep being skeptical
If the Alloy stem would be better.. I am tempted to order one separately if that would be possible.

There is a new alloy stem??

I went to the website and indeed it says that.. I am looking forward seeing it Kelvin.


I am still struggling with the flex in the handlebar.. I get that the flex in the handlebars give more comfort.. but it is a little too much for my liking. Especially when cracking already two stems (the one now is holding just fine), I have some trust issues  
But after seeing the video of Alex on GCN on his China build with his horrible handlebar flex, mine is all things considered not that bad.
But he listed a flexible steerer tube as the problem (not the handlebars/ stem themselves).

Additionally.. still debating if I want to go through the trouble of cutting the handlebars are bit shorter (the longer the reach/lever, the more flex you have ofcourse).
But then I would have to go through the trouble of bleeding brakes again etc...

People in this thread using Riderever triva, what brake fluid are we supposed to use with it? And what fitting if I want to resize the brake hoses?

I used standard Shimano mineral oil. For fittings, I just contacted them and they sold and shipped it to me

I am curious about how you achieve such a low price as I calculated what I want to be >3000$. Do you mind sharing a part list?

I also tried a budget build. But I got it to 2.8k at the end. Almost everything secondhand.
You can see the full build spec a couple of pages back

Has this already happened to anyone here?
Even when I first received the stem, I already found that the finishing quality wasn't great...

Unfortuneatly yes.. the top half of the stem cracked twice for me (they had already send a replacement but that cracked as well.)

Now they shipped a whole new stem (top and bottom). I replaced it this week and now it seems to be fine. It is supposed to be an improved design (although i can tell them apart).
I am very scared to tighten them. I only went to 3.6NM but that seems to do the job. No crack this time.

Edit: I have to say.. they responded very friendly to all my (irritated  ) messages. They kept replying to find solutions to the problem and kept shipping them out to me for free. So overall for the service a big thumbs up!

My TT build is almost done, thanks to this discussion for all the tips and tricks!

Still left to finish:
- Extensions (larger extensions on their way from VB)
- Front Hydration (Universal BTA mount from Fast TT)
- 3D printed toolbox from @mattgolt

Build Details
SRAM Rival AXS D1
SRAM RED D2 Crank 175MM
Passquest 54T
SRAM DUB T47
RIDEREVER Triva
SRAM Wireless Blips (Pair)
76 Projects Blip holders
Elitewheels 50mm (disc to come)
Continental gp5000
SRAM Force 10-33

That paintjob looks absolutely stunning.

Also be careful not to  overtightend. Otherwise it will "crack" and you will need a new stem.

Don't ask me how I know that .

Happened to me twice now with the Velobuild custom stem..
Saw a crack developing on the clam of the top stem cover. Reached out and immediatly and was send over a new top cover.
Happily switching the stem covers.. but cracked immediatly under low torque again (2nm or so..)

Reached out again and the response was: we changed the mould to increase strength (can only imagine it happens frequently), we'll send out the new version soon
Now waiting for the new version to arrive.


I am also looking now at alloy stems in case I don't get on with this system.. any suggestions? (needs to be very low stack because the steerer tube has already been cut very short)

I was totally up to tinkering and solving all these tiny issues - as i completely expected from a Chinese frame.

The stuff that challenged me most was also the cockpit.. bars slipped on the first ride (because I "too carefully" torqued them up).
Now with greater torque, everthing seems fine.
Coincidentally, I asked a couple of hours ago to VB for the max torque just to be sure. I will edit it in the post later when they reply =)
Edit: they responded that the max torque is 5NM

I actually never build a bike up before.. but it was surprisingly more straight forwards than expected.
Also had to cut the fork by myself.. but with care that was easily enough.
But.. for sure.. specific torque settings would have given me more confidence in the build stage and test rides

I learned so much from this thread (and forum as a whole), so the least I can do it to show you the finished build:

VB-TT-023 build with:

Ultrega crank (with powermeter)
Passquest 50T chainring
Praxis T47 BB
SRAM Rival AXS RD
SRAM wireless blips
Shimano 11-36T cassette
KMC 12s chain
Riderever Trivia brakes
Bontrager COMP5 wheels
Shimano Ultegra 160 disk brakes
Schwalbe one 25mm tires (tubeless)
Bontrager Hilo Comp TT saddle

Bought almost everything (except for like chain/chainring/..) second-hand to reduce the cost. And that got me to a proper finished build at 2.8k
