Looking for a road racing disc frame that can fit 30 or 32mm tires.

[pearl]

Hello, looking to move on from my Van Dessel Motivus Maximus at some point and was starting to do research. Currently use this for most of my training, some light gravel riding. I still want it to be quick and snappy.

Here’s what I’m looking for:

Road racing geometry, nothing endurance related
Flat mount disc
Standard seat post/stems, nothing proprietary (currently run a 56 with a 140mm stem and 42cm bars, 58s are usually too big, my fit is kind of weird I guess?)
Clear up to 32s, 30 at a minimum

What’s the frame I should be looking for.

Dengfu has an r02 disc, uses a circle carbon seatpost with your standard clamp, dont know how youll li the geo tho.

I could be way wrong but a lot of “race” frames means aerodynamic for open molds, and when theres aerodynamic, theres a proprietary D seatpost. FWIW, snapped my dengfu r12 post, they shipped another one out THAT night.
The only time ive seen a circle seatpost is with a lightweight frame.

Speaking of which, anyone got a super super light frame built out of open mold parts? I saw someone got a 4.83 kg supersix, curious if anyones actually hit 6kg maybe?

I could do a proprietary seat post but usually I have nightmares of them breaking!

What link do you have to that frame? Any photos of your tire setup and clearance?
Seeing some mention 25 as the max, others say 32mm?

I own the r12. Imo, why spend the same price when u can get internal routing?

R12 is decent. I need to get comfortable around it but i havent dive bombed 40 mph on it. Its stiff and aero. Theres a pretty big saddle/bar drop so its very race geo’d. And i agree that seatposts breaking on open molds is an issue but like i said dengfu let me buy one that night, said they needed to paint it, shipped it out. Here in two weeks. Overall, a happy customer. My crash gave me speed wobbles, fixed it, loose headset/wheel (idk). My only gripe so far is it has creaked bc of the rear thru axle before, ive had to take it out and put it back on, regrease, ect, but i put a good amount in yesterday and my 25 mile ride today i didnt hear anything, dead quiet. The paint job isnt strong too, a chaindrop caused a really good scratch on it so id actually recommend doing a gel coat or clearcoat, something of that nature to make it more durable, but i bet thats with all open mold frames.

There are some chiner builds on WW, here are some of them:
4.7kg ICAN A2 https://weightweenies.starbike.com/forum/viewtopic.php?f=10&t=163352
5.25kg Hongfu FM079 https://weightweenies.starbike.com/forum/viewtopic.php?f=10&t=162485
6kg Dengfu FM208 https://weightweenies.starbike.com/forum/viewtopic.php?f=10&t=162485

Also here's a very long thread discussing chinese/open mold road frames https://weightweenies.starbike.com/forum/viewtopic.php?f=3&t=113717

Hi!

I have ordered a VB-R-168 from Velobuild. According to Velobuild it should clear 32mm tyres and according to some of the current owners in the specific topic it will easily fit that. Does use a proprietary seat post I assume. http://www.velobuild.com/products/2021-vb-r-168-carbon-fiber-road-frame-disc-version-integrated-hidden-cables.

VB-R-177 is the round seatpost frame from Velobuild.

Very light but fits 32mm and with a low stack height.

it looks like both of those use integrated stems/steerers though, i dont think they will work for me. i could probably fit on a 57 in those models but its too much of a gamble for me...

Wanted to compare the different geo's but I cannot really find a van Dessel MOTIVUS MAXIMUS in size 56, I can only find 55 or 57. Are you sure you have a size 56?

sorry its a 55!

Velobuild 168 - there is a thread on here about it. Lots of people are buying these.
