Reverb AXS Dropper Seatpost - 200mm B2

RockShox Reverb AXS Dropper Seatpost - 200mm B2 delivers the cleanest way to add big-travel dropper performance to a modern MTB cockpit: fully wireless actuation, fast setup, and consistent feel without hoses, bleeding, or internal routing. Built to slot into the SRAM AXS ecosystem, it shares the same battery, charger, and control logic as other AXS-enabled components—making it a practical upgrade for riders who want fewer cables and more precise dropper control on technical terrain.

Key advantages for real trail use

• 200mm drop - Maximizes clearance for steep descents and aggressive body positioning without giving up pedaling height when fully extended
• Wireless AXS actuation - Eliminates hoses and routing for quicker installs, cleaner frames, and simpler bike swaps or travel builds
• ActiveRide air-only internals - Adds purposeful compliance when the post is slightly dropped, improving comfort and traction on steep, technical climbs while staying firm at full extension
• Shared AXS battery system - Includes battery and charger (USB-C charger cord sold separately) that works across other SRAM AXS components for streamlined spares and charging
• Broad saddle compatibility - Compatible with all saddle rail types for straightforward fitment across trail, enduro, and e-MTB saddles
• AXS Controller required - Designed to pair with a separate AXS Controller (sold separately) for consistent, repeatable lever feel and customizable control layouts across the AXS cockpit
