Reverb AXS Dropper Seatpost - 100mm B1

RockShox Reverb AXS Dropper Seatpost - 100mm B1 brings fully wireless dropper performance to modern MTB cockpits, eliminating hoses and internal routing while integrating cleanly with the SRAM AXS ecosystem. For riders already on AXS, it’s a straightforward upgrade: one shared battery platform, consistent control feel across components, and quick installation with basic tools.

5 reasons this wireless dropper belongs on an AXS-equipped trail bike

• Wireless AXS actuation - Delivers consistent, precise saddle-height changes without hydraulic lines or routing headaches
• Fast, low-fuss installation - No hoses to cut/bleed; simplifies setup, swaps between frames, and travel service
• ActiveRide compliance - Adds a more forgiving, traction-friendly feel on steep, technical climbs when the post is not fully extended
• Shared AXS power - Includes AXS battery and charger, compatible with other SRAM AXS-enabled components to streamline spares and charging
• Broad saddle compatibility - Works with all saddle rail types for easy fit with existing saddles

Note: AXS Controller required for operation (sold separately).
