VeloBuild VB-R-268 frame

[Someguy96]

Is anyone able to tell me the size of the bolt needed for the out front computer mount underneath the bars?

I'm trying to find an out front mount but struggling. Does anyone have a good suggestion for a Wahoo Bolt?

I don't know the exact dimensions, but i'm using this mount if that helps : https://a.aliexpress.com/_EvDzFtu

The frame comes with 30mm in black metal spacers plus the carbon cone/spacer which sits over the head tube.

So question. Would you chance it fitting more spacers than that under the stem? I read on Google that 30mm is the max normally.

The taller, heavier, aggressive you are, the sketchier it becomes. If you use a lot of spacers, it's a good idea to use a longer / extra long expander plug. But on this bike it's a proprietary part.
Pretty sure you can use 45 or 50mm and you'll still be fine. Also, presumably, the more spacers you use, the less likely you are to be a watts monster and a daredevil in the 1st place.

Can anyone tell me what is the native disc size for the front and rear? Both 160, 160f/140r, or both 140? Or else, would I need an adapter to mount 160 both front and rear?

I have a shimano 105 groupset .
Front is compatible with 160 but you'll need and adapter for the rear if you want to use 160. Otherwise it seems to be 140 without an adapter.

Thank you all for the helpful insights in this forum!
I plan to build a bike using either the 268 or the 177 frame. I am currently gathering all other components. Which cable length would you suggest for a di2 groupset?
