The RockShox Reverb AXS is a wireless dropper seatpost with 200 mm of travel in a 30.9 mm diameter. It uses the same battery, charger, and controller as SRAM AXS drivetrains.

What it's for

A dropper for trail and enduro bikes with no cable or hose to route. It is approved for electric bikes.

How it works

AXS: the post is controlled wirelessly by a SRAM AXS controller. The AXS app sets up controls and updates firmware.

Air over air: an air spring design RockShox built for durability.

ActiveRide: a small amount of give when the post is lowered slightly for technical climbs, while the fully extended position stays rigid.
