Overview
What is the Black Inc Integrated Aero Barstem AB02 built for?
The Black Inc Integrated Aero Barstem AB02 is a carbon integrated barstem that Black Inc calls the new benchmark aero barstem for road and gravel. Black Inc says it gets its speed two ways: it helps the rider reach a more aero position, and it slices the air more efficiently. The tops have a 40mm mid-depth profile, and the narrower hoods let you rest your hands on the horns of the levers with your forearms flat, which Black Inc says reduces your frontal area. Chris Froome contributed to its development after riding the Factor OSTRO VAM and feeling it deserved a barstem upgrade.
The tops sweep back 3 degrees with chamfered corners that add wrist clearance when sprinting, and the drops flare 7 degrees to measure 29mm wider than the hoods. For road, Black Inc says to size the bar at the drops for narrower hoods and a more aero position; for gravel, size it at the hoods for the added control of wider drops. Fully internal cable routing is supported for electronic and disc brake groupsets only. The Black Inc V10 computer mount is included and works with Wahoo and Garmin computers, though Black Inc lists the Garmin 1050 and Wahoo Elemnt ACE as not compatible. Black Inc designed the AB02 to pull double duty as both a road and a gravel bar.

Black Inc says fully internal cable routing on the AB02 is supported for electronic and disc brake groupsets only.
Can the Black Inc AB02 Aero Barstem be used on a gravel bike?
Yes. Black Inc designed the AB02 as both a road and a gravel bar, using a 7 degree flare that places the drops 29mm wider than the hoods. For road, Black Inc says to size the bar at the drops and benefit from narrower hoods that place you in a more aero position. For gravel, size it at the hoods for the added control of wider drops when the terrain demands it.

The AB02 includes the Black Inc Computer Mount (V10), which is compatible with Wahoo and Garmin computers. Black Inc lists the Garmin 1050 and Wahoo Elemnt ACE as not compatible. Black Inc describes the bar's mount as GoPro style, with angle adjustment and a more supported second mount for a light or action camera.

Black Inc makes the AB02 in widths of 36cm, 38cm, 40cm and 42cm and stem lengths from 80mm to 140mm in 10mm steps.
