Reverb AXS Dropper Seatpost - 175mm B1

RockShox Reverb AXS Dropper Seatpost - 175mm (B1) brings truly clean, modern dropper performance to trail and enduro bikes by eliminating hydraulic hoses and cable routing. As a fully wireless, electronic dropper seatpost, it installs fast with a multitool and integrates with the broader SRAM AXS ecosystem using a shared battery and charger—ideal for riders who want dependable actuation, a simpler cockpit, and straightforward serviceability.

Key advantages for real-world trail riding

• 175mm drop for modern MTB fit - Adds meaningful clearance and body positioning range for steep descents, technical moves, and aggressive cornering
• Wireless AXS actuation - No hose, no bleeding, and no routing through the frame, reducing install time and avoiding common cable/hose friction issues
• ActiveRide air-only internals - Provides controlled compliance when the post is not fully extended, helping maintain traction and comfort on steep, technical climbs; fully extended it returns to a firm, stable pedaling platform
• Shared AXS battery ecosystem - Includes battery and charger compatible with other SRAM AXS components for simplified spares and charging routines
• Broad saddle compatibility - Designed to work with all common saddle rail types, making it easy to transfer an existing saddle without special clamps
• AXS controller required - Uses a separate AXS Controller (sold separately) to complete the wireless dropper setup
