The RockShox Reverb AXS is the benchmark wireless dropper post for mountain biking. Combining hydraulic actuation with SRAM's AXS electronic ecosystem, it delivers instant, precise saddle height changes at the press of a button — with no cable to route, snag, or replace. The result is a cleaner cockpit, faster response, and one less maintenance task on the trail.

• Wireless AXS actuation — no dropper cable or housing required
• 34.9mm diameter for frames specifying the larger oversized seatpost standard
• 175mm travel for generous saddle drop on enduro and all-mountain terrain
• Infinite height adjustment — lock off at any point within the travel
• Hydraulic cartridge design for consistent, temperature-stable performance
• Battery and charger included; integrates with all SRAM AXS components

Reverb AXS uses a self-contained hydraulic cartridge that requires no bleed maintenance and performs consistently across a wide temperature range. The AXS battery charges quickly and delivers long ride life, while the AXS app allows firmware updates, actuation tuning, and multi-component control. The B1 generation refines the internals for improved reliability and smoother action.

Compatible with 34.9mm seatpost frames. Remote and AXS Controller sold separately. Integrates with SRAM AXS Eagle, AXS Road, and Reverb AXS ecosystem components.
