Reverb AXS Dropper Seatpost - 225mm B1

RockShox Reverb AXS Dropper Seatpost - 225mm (B1) brings fully wireless, electronic dropper performance to riders already invested in the SRAM AXS ecosystem. With no hydraulic hose and no internal routing required, installation is straightforward and cockpit layout stays clean. The long 225mm drop is aimed at modern trail and enduro setups where maximum clearance improves body position, confidence, and control on steep or technical descents.

Why riders choose Reverb AXS for a long-travel dropper build

• Wireless AXS actuation - Delivers consistent, precise post movement without hoses, bleeding, or cable friction; simplifies frame swaps and service.
• Shared AXS battery platform - Includes battery and charger that are shared across compatible SRAM AXS components to streamline spares and charging habits.
• ActiveRide air-only internals - Adds built-in compliance when the post is dropped for improved traction and comfort on steep, technical climbs, while staying firm and stable when fully extended.
• Customizable controls (AXS ecosystem) - Supports AXS control customization to match rider preference and cockpit ergonomics (note: AXS Controller sold separately).
• Broad saddle compatibility - Works with all saddle rail types for easy pairing with existing saddles and builds.
