I'm not far off pulling the trigger on purchasing this frame, checked out all the other options and this just feels like the right frame for me. Just need to sort out final colour and costing (Chris has been super helpful answering all my questions), thinking mat black to match the wheels. My build will take a few months as the wheels are going to take a while to build. Hopefully on the road early Jan.

Planning to double sided sticky tape the bento box, not as clean a solution but allows for my ProfileDesign FC35 to be custom mounted in front of it. I plan on running the stock bars, unless my bike fitter says not to.

All the bike builds posted here are nice and clean looking.

If you pull the trigger, ask Chris to include some extra spacers for the aero bars. While they can be bought 3rd party it’s very handy if the bike comes with extra that aren’t needed, rather than not come with them but are needed. I myself need another 35-50mm stack worth.

Finally finished my VB-TT build. Only ridden on Turbo so far so no idea on road feel / secureness of contact points (particularly concerned about Bars / Seatpost slipping on bumpy terrain)

1st proper ride with the VB-TT-023 today

Bike is truly stiff, broke alot of PR’s today on a route that i havent been on for several months. Considering that this is my first time on a TT bike, i am truly happy with the frame and my build, no issues on a 63 mile ride with 1k feet of elevation, i completed the ride in 3:06.22 averaging 20.1mph on 204watts.

What's the fit like for your Alpha One around the headset area? I just got both my frame and the Alpha One but its quite skinny compared to the stock Stem?

I've gone down this route for my VB TT-23 build (not built just yet). Gone with:

SRAM Force Rear Mech (36tooth max)
11-34 Shimano Cassette
Dura Ace Crankset w/ 56t Pass Quest 1x Chainring
RideRever Trivia Hydraulic TT Brakes
2 sets of 2 AXS Wireless Blips (1 set on Bar Ends and 1 on the Brake Levers)

Most of the TTing and Tri's I do are flat-ish or enough to get by on a 1x chainring. When I need to I will simple buy a SRAM Red FD and double chainring. Went for the Dura Ace Crankset because its quite light. Hoping its all compatible...

I also ordered this frame a few weeks ago, still waiting for it to arrive. I also asked them to add some bento box rivets to the top tube which they said yes to, so that's an option.

That's pretty sweet that they did that. I see in some of the GAs that they intended to have in-built bento in the top tube of the frame but it obviously didn't make the cut for the production models.

Have actually just pulled the trigger on ordering a VB-TT-23 too for a cheap Disc Brake TT build but is yet to arrive. Frameset looked decent but only concern (not even concern, just my petty-ness) is the Basebar and the exposed bolts on the underside.  My frameset is yet to arrive but thinking of getting some other basebars to address the aforementioned issue.
Don't suppose you could measure the width of the stem clamping section could you please?
Thanks
