Cyclocross Frames, Wheels & Components / Re: XMCS: 2026 Aero Gravel bike
« on: August 01, 2026, 04:59:44 AM »
After reading the topic about the new aero gravel bike, I was really happy to see that.

As a Dutchman, I am now looking for a gravel frame that can handle 57mm. That way, a 60mm beach tire will also fit.

There is no better geometry for beach races. With converted MTB frames, the stack heights are always way too high.

Now I see the price; it is absurdly high, almost 2k, and that's knowing it can only handle 1 x 46t.
I am curious when the updated version will come out that can handle a max of 52/54t.
Sometimes speeds of 65 km/h are reached for kilometers on beach races, so 46t is way too small.

Hopefully, I will still be surprised.

Thanks a lot for the info on the Kogel OSPW! I’d been looking at AliExpress for a while.
That makes a difference; I use the TT bike for time trials rather than long-distance rides, so a BTA system is out of the question.
I got some really nice adapter pieces from AeroCoach so it fits perfectly against the spacers.
 If you're interested, I can always show you some photos.
The distance works fine for me. I’m quite small and slight-built myself.

Here’s a photo of the build as of today
I got the wrong bb originally, got the right one a SRAM T47 Inboard, also the ZRACE rotors where sketchy, so I got SRAM Paceline. I also got the LEAP components sram aero handle.
Thinkering on the hydration system since I’m using this bike for Ironman training/racing.

It turned out to be a beautiful bike.
I did notice that you used my build as inspiration 😉
 How do you find the reach from your handlebars to your brake levers? I actually shortened mine by 3cm, and it’s much better.
 I see you also used the base plate from the VB handlebar to mount your 15-degree Aerocoach extensions. Just out of curiosity, why did you set it up that way?
Otherwise, a stunning build!

PS: I love your OSPW system—where did you get it? 🤗

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.

Finally, I was able to properly test the bike outdoors during a long ride.
Using a borrowed disc rear wheel from a friend.
I am also still looking for a rear wheel.

During the outdoor ride, I tested the bike quite well with a short interval block of 10 minutes at 325 watts at 64kg with an average speed of 49.5 km/h.
The bike is truly amazing; I look forward to future time trials.

All in all, the bike is 10/10.
Service Velobuild ( Chris ) 10/10 big shout out to Chris for fast response !
Price-quality ratio 10/10

My next bike frame will definitely be a Velobuild again.

Thanks. And the torque u were using was still 6Nm? Or did u increased it as a shorter screw is not applying a stronger clamping force or grip?
Any assembly paste in addition?

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.

I encountered the exact same issue, I think the problem is only present with S sized frames, as the headtube is shorter. My steerer tube has a carbon "bridge" inside, so the expander can't be inserted any deeper.

What expander did you buy afterwards? I'll have to get one as well, which is slightly annoying.

I bought a 25mm expander instead of the 45mm

Is anyone using the new updated stem? Has it fixed some of the issues people have had?

Also, has anyone imported into the US recently? Were you hit with a lot of extra costs?

Im using the alloy updated stem its looks better then the carbon stem.
All my problems with the handle bar is solved

 
Hi, what Leap Aero Grip Shifter size did you order? Thanks!

https://leapcomponents.com/product/sram-aero-disc-brake-grip-shifter/

I measeured the basebar 23.7mm
So I ordered the size 23,7mm it fits perfect.

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

Yes, it's available. If you check the velobuild website, it's listed in the description. I'll post a photo as soon as I receive the stem.

After being sold on time trial riding for a while, I wanted to switch from rim brakes to disc brakes.
After reading a lot on this forum, I decided to go for the Velobuild.
I ordered through the Velobuild website after Chris checked the sizing.
I chose a size S.
I'm 176cm tall with an inseam of 80cm.
My saddle height is 70.9mm from the center of the crankset (165mm).
I have quite short legs, and that became apparent when I unpacked it and tried to assemble it.
The seatpost definitely needs to be shortened.

The frame was delivered super fast within 14 days of ordering, and the box was completely intact and undamaged.
After unpacking, I encountered my first setback:
the top tube bolts
I hadn't asked for this, and it wasn't visible in the photos on the website.
I ask Chris about my problem he would change the pictures on the website.
Everything else was very well packed,
and all the parts were complete.

Parts list :
Frame: Velobuild TT size S
Shifters: Sram s900 with leap components
Sram Force E1 Derailleur
Sram blips with leap components
Evosid cranks 165mm with 58t
Sram Force e1 flattop chain
Sram Force e1 10/30
Cema Bottombracket t47
Aerocoach ascalon cockpit extensions
Front Wheel Aerocoach Titan 100mm with Conti TT
Disc Wheel Still looking for it some tips?

I'll mainly use the TT for fast time trials.
The setup will therefore be 1x12.

I started building.
I started by spraying all the bolts black.
This should actually be standard.

After shortening the fork, I discovered the first problem.
The included expander plug was too long, or was it simply a dirty fork?
The solution: I installed a shorter expander, 26mm instead of 45mm.

When I had the carbon stem in my hands, I already had my doubts about its strength.
After reading on the forum, I knew this was a common problem.
After receiving the frame, I immediately emailed Chris to ask why I hadn't received the alloy stem, even though it was listed on the website.
Unfortunately, because of the holidays, this took three weeks to send. Its on my way atm.
I couldnt wait to build this monster ,So I tried the carbon stem.
I did it like this: I applied a thin layer of carbon paste to the base bar.
I tightened the expander bolt 2nm and the top bolts to 5NM, so I could then tighten the bottom bolts according to Chris's advice 5nm
Unfortunately, the stem failed at 2NM and split in two at the front.
I'm glad the aluminum stem is on its way to me.
Fortunately, Chris is easily accessible and acts quickly, which I'm happy about.
I'm waiting for the alloy stem this week so I can continue with this monster.
I can't wait to ride it.

Annyone Else had problems with the carbon stem?

Will be continue..

Do you find it a little awkward to press the shift button? Love how they look but having the shift be on the brakes seems more ergonomic.

They feel good when you hold them.
I mainly shift with my ring finger; they don't require much pressure.
They look great, and I think they enhance my bike.
I use the Leap components both one on the extensions and on the basebar.

I ordered the 23.7 from Leap. They fit snugly on mine. I installed them to the correct recommended NM, and they're rock solid when combined with the SRAM S900.  8)

This looks like a diamond. 8)
This is exactly what the Dutch gravel market wants.
A gravel frame with clearance for beach tires. So it's multifunctional for gravel and beach races.
I participate in beach races all winter long.
Only on a converted Berria Bravo MTB frame. So this frame will be a godsend for me. I'm curious when it will be released.

I'm curious how the frame will be configured with boost or non-boost?
