Reverb AXS Dropper Seatpost - 250mm B1

RockShox Reverb AXS Dropper Seatpost - 250mm B1 brings true wireless dropper performance to modern trail and enduro bikes, with long-travel adjustability for steep, technical terrain and a clean cockpit free of hoses and routing. Built around the SRAM AXS ecosystem, it uses the same removable AXS battery and charger used across compatible SRAM components, while delivering fast, consistent actuation and a straightforward setup that’s ideal for frames with tight internal routing.

With 250mm of drop, this version targets riders who want maximum saddle clearance for aggressive descending, while ActiveRide air-only internals add controlled compliance when the post is not fully extended—useful for maintaining traction and comfort on steep, technical climbs without giving up a solid, locked-out feel at full height.

What makes the 250mm Reverb AXS a standout upgrade

1. Wireless AXS actuation - Eliminates hose routing and simplifies installation and service access, especially on frames with complex internal paths
2. 250mm travel range - Maximizes saddle clearance for steep descents, body-English, and modern long-travel trail/enduro positioning
3. ActiveRide air-only internals - Adds compliant support when not fully extended to improve comfort and traction on technical, seated climbing
4. Shared AXS battery ecosystem - Includes AXS battery and charger for convenient power management across compatible SRAM AXS components
5. Broad saddle compatibility - Works with all saddle rail types for straightforward fitment across common saddle standards
6. Controller note - AXS Controller sold separately; required for operation and to tune control layout within the AXS ecosystem
