I ordered it from aprotobike.com along with my computer mount. It's the -17 Kalloy Uno transition spacer. I needed to run a split spacer (5mm) underneath it so the hoses could clear the VB ACR top cap.

Hello I've built up my bike! I'm running SRAM Rival AXS with a 52/39 and 10-36t combo. 60mm wheels from Serenade with Pillar 1420 steel spokes (1365g). For cockpit I went with 28cm Bikedoc bars and a Kalloy Uno stem for ez adjustability in the future. My frame has the chainstay clearance issue which is super annoying... The shifting is really quite bad in the higher gears since I can't adjust the B-gap close enough. The hanger also seems to be a little bent, so i will provide an update once I get the hanger aligned.

First impressions are pretty good! This is my first carbon frame coming from a round-tube Ti bike. I actually noticed that it was more comfortable over rail road tracks and potholes even though I am using narrower 29/30mm tires than the 32mm on my Ti bike. Stiffness -- I can't really judge, I am 58kg and my sprint is shite so it's definitely stiff enough for me. The front-end handles quite nicely on my 49cm size.
Aero wise, it's a bit too cold and windy currently to test it, but it's not dramatically faster than my Ti bike which is similar in position. I'll see how it feels when I race it during the season.

Building it up was not super easy. The rear caliper mount had paint sprayed over it, so I had to file it down a bit; the caliper is still visibly crooked but not rubbing -- I need to face it down in the shop. Front brake mount was fine. Upper headset cup was a bit tight for the bearing but it went in fine. There's quite a lot of plastic in my headset stack so I've had to adjust the preload a bit so far due to the parts creeping. Also, the bottle cage mounts are too close together. The bottles interfere! I need to move the downcage up a little bit. All fixable things except the DAMN CHAINSTAYS! Going to reach out to VeloBuild and see what they say about it.

Tl;dr: sexy bike, but beware if you're running SRAM...

Yes I ordered the green clear coat frame. Here it is, size 49.

Got my frame. Here are some weights! Size 49 with glossy tinted clear coat finish.

482g fork
208g seatpost
48g di2 battery holder
35g F thru axle
41g R thru axle
58g included compression plug
12g metal c ring
34g seatpost wedge
11g seatpost grommet
30g UDH hanger
22g ACR adapter
61g headset bearings
1375g frame with grommets, FD hanger and bottle bolts

I also ordered one. I didn't want any of their handlebars or stems and got a 60 USD discount on the frame. I'm going to build it up with SRAM Rival AXS and a set of Zen 60mm wheels.

How many backers does it currently have? It shows 2 for me which seems low and it's giving me some hesitation about joining; not sure if it's a bug on my end?
