Reverb AXS Dropper Seatpost - 125mm B2

RockShox Reverb AXS is a wireless electronic dropper seatpost built for riders who want clean cockpit setup, fast installation, and consistent actuation on technical trail and enduro bikes. This 125mm B2 post integrates into the SRAM AXS ecosystem, sharing the same battery and charging hardware used across AXS components—ideal for simplifying spares and keeping controls familiar across the bike.

Key reasons riders choose this wireless dropper upgrade

1. Wireless AXS actuation - Eliminates hoses and internal routing hassles for a cleaner build and easier service access
2. AXS ecosystem compatibility - Uses the same rechargeable AXS battery and charger system as other SRAM AXS-enabled components for streamlined charging and spares
3. ActiveRide air-only internals - Adds controlled compliance when not fully extended, improving comfort and traction on steep, technical climbs while remaining firm when fully extended
4. Customizable control layout - Works with AXS wireless controls to let riders place and configure dropper actuation to match cockpit preferences (required AXS Controller sold separately)
5. Practical fit details - Compatible with all saddle rail types and designed with improved battery clearance across the Reverb AXS range

Includes AXS battery and charger (USB-C charger cord sold separately). AXS Controller required and sold separately.
