Re: Velobuild AERO GRAV Frame

What does your frame and fork weigh, is it even close to the numbers on velobuilds site?

Sorry for the slow response here, the whole system (frame size M, fork, seatpost, handlebars) came in at ~2150g, which is only 100 grams over the quoted weight for the size M. This was also with a 420/110mm handlebar, so maybe that accounts for the increased weight as they might use the weight for the smaller bars.

Re: Velobuild AERO GRAV Frame I've now ridden this for 200km and here's my take so far:

Handling & Geometry:
Fairly well balanced, although the front is prone to a bit of understeer in my view. This is probably a personal preference, and would make for a more stable steering experience compared to something with a steeper steering angle. After you get used to it it's actually quite good when cornering on the loose stuff, less twitchy compared to some of the racier options out there when going down sharp descent. But I prefer a little bit more active steering closer to road bike control. No toe overlap with Sphyre shoes if anyone wants to know.

Stiffness and responsiveness:
Short chainstays make for fairly rapid response, although my comparisons with other race gravel bikes would suggest it's not as stiff in the BB area, as the power transfer feels softer compared to i.e. the Kanzo Fast and my Lightcarbon. Read a page back from someone stating the bike is very stiff which is not my impression at all. Although I wouldn't go as far as to say that it's spongy, it's for sure not as stiff as my Kanzo Fast (which is known for it's rather stiff/ harsh character). Integrated handlesbar is fairly rigid, not harsh but not overly stiff either, well balanced.

Build experience
All went smooth, including setting up the brake calipers (which can be a bit hit or miss depending on the facing). T47 BB went in smooth and sits flat against the shell. Frame is completely latex moulded and has a perfect inside finish. Seatpost, handlebars and fork however use a bladder moulding tech so the routing through the bars was a bit messy, almost lost my routing tool in there and had to use some force and arm grease to get it unstuck. Overall though it went together just fine, headset was well done without too much play in the bearings and so far not seatpost slippage despite what some people have reported about Velobuilds previous designs with d-posts. Not overly excited with the UDH hanger, in tandem with my GRX derailleur it's made removal of the rear wheel way more fidgety compared to my other bikes, partially this might be due to the clutch and design of the derailleur though. Also not too happy about the 1.5pitch on the UDH thread as it makes it more difficult to find a direct mount replacement over on aliexpress (most seem to be 1.0mm thread pitch)

Setup:
Frame: Velobuild Race Gravel
Handlebars: Velobuild Integrated
Gears: GRX 1x11 11-40t, Ultegra shifters
Brakes: GRX calipers, 160mm + 160mm Rotors

Tires: Rene Herse Snoqualmie 44mm (on gravel 2.0bar front, 2.5bar rear, on pavement 3.5+4.0bar)
Cranks: Easton EC90 SL
BB: AliExpress scraps

Re: Velobuild AERO GRAV Frame I've had the chance to put in some longer rides over the last few weeks with my new setup – a couple of rides on 40 mm Challenge Strada Bianca tires, mostly on tarmac and some Cat-1 gravel.

First impressions: I’m really happy with how the bike performs. Both in terms of ride feel and on Strava segments, it’s noticeably faster on road and light gravel compared to my Cube NuRoad. The frame definitely seems to offer more aero potential, and the fit is spot on for me.

Honestly, for minimalists, this bike could easily be a true “one-bike-fits-all” solution – as long as you’re not doing road races, it covers just about everything. I even find myself reaching for the Velobuild with the 40s for pure road rides instead of my SL7, just because it’s so much fun. It almost rolls as well as a road bike, but can handle gravel no problem.

Last week, I took it out for some proper gravel sessions, including some seriously rocky sections and even singletrack. It’s quick and agile, and the 48 mm Thundero tires definitely contribute a lot to the ride quality. It also performs impressively well on 2.1” Thunder Burt tires, proving its versatility across different terrains. The Zipp SL80 bars are also growing on me – didn’t love them at first, but now I really appreciate the grippy, textured tops, especially in aero hoods and puppy paws position.

Only minor regret: in hindsight, I might have chosen the frame in “gloss over carbon” instead of matte black. Still debating whether to go 1x13 with the drivetrain, too.

All in all, super satisfied with the bike. It may get its first race outing this weekend.

And… the next China frame project is already in the works – more on that soon!
