FAQ

Does the Black Inc AB02 Aero Barstem work with mechanical shifting?

No. The Black Inc AB02 Aero Barstem supports fully internal routing for electronic and disc brake groupsets only, and Black Inc lists external cable routing as not applicable. Plan on an electronic groupset with disc brakes.

Can the Black Inc AB02 Aero Barstem be used on a gravel bike?

Yes. Black Inc designed the AB02 to work as both a road and a gravel bar, using a 7 degree flare that puts the drops 29mm wider than the hoods. For road, Black Inc recommends sizing the bar at the drops so the hoods sit narrower; for gravel, size it at the hoods so you get wider drops for control.

What computer mount comes with the Black Inc AB02 Aero Barstem?

The Black Inc AB02 Aero Barstem comes with the Black Inc Computer Mount (V10). Black Inc describes the mount system as GoPro style, with angle adjustment and a supported second mount for a light or action camera.

How do I pick a size for the Black Inc AB02 one-piece cockpit?

Choose the Black Inc AB02 size that matches the stem length and bar width you already ride and like, because a one-piece barstem cannot be adjusted for length the way a separate stem can. Black Inc makes the AB02 in widths from 36cm to 42cm and stem lengths from 80mm to 140mm. If you are not confident in your current fit, sort that out first; the lab is happy to help.

Best For

Road racers and fast gravel riders running an electronic disc groupset with fully internal routing, who already know their fit and want a clean, integrated aero front end. The 36cm / 140mm suits a narrow, long, aggressive road position. The 40cm / 120mm suits a more typical road fit, or a narrow gravel setup sized at the hoods.
