Reverb AXS Dropper Seatpost - 175mm B2

RockShox Reverb AXS is a wireless mountain bike dropper seatpost built for clean cockpit setups and fast, consistent actuation—without hoses, routing, or bleeding. This 175mm travel B2 version integrates directly into the SRAM AXS ecosystem, sharing the same battery, charger, and control logic riders already rely on for AXS drivetrains.

Wireless Reverb advantages that matter on-trail

1. AXS wireless actuation - Eliminates hydraulic lines for simpler installs, easier bike swaps, and a cleaner bar and frame setup
2. Shared AXS battery system - Includes AXS battery and charger (USB-C cord sold separately), matching other SRAM AXS-enabled components for streamlined spares and charging
3. ActiveRide compliance mode - When not fully extended, adds controlled comfort and traction for steep, technical seated climbing; fully extended, the post remains firm and supportive
4. Air-only internals - Simplifies the system while delivering smooth dropper performance and ActiveRide functionality
5. Broad saddle compatibility - Works with all saddle rail types for straightforward fitment across MTB saddle choices
6. Controller note - Requires an AXS Controller (sold separately) to operate
