KOCEVLO X01 Road Bike Full Carbon Fiber Stem Integrated Bicycle Handlebar For 28.6mm With Spacers Cycling Parts Accessories

I have a VB-R-066. I first built it up using this upper headset assembly from Ritchey. It enables the hydraulic hoses to enter the frame via the headset dust cover, so you can use a separate handlebar and stem. Great if you want to reuse existing parts you have, or if you want to easily swap handlebar and stem for fit reasons without cutting any hoses.[...] Later I swapped to this Kocevlo integrated handlebar, trading function for form: https://vi.aliexpress.com/item/1005006561735597.html
Both fit the frame. I had to sand the Kocevlo dust cover a little to prevent rubbing on the frame after tightening everything down, but that was straightforward.
