RockShox Reverb AXS B1 Wireless Dropper Post
The Reverb AXS completes the AXS ecosystem by giving rider customizable controls, easy install, and a shared battery, charger, and controller. Built for GX, X0, and XX riders, Reverb AXS ensures smooth control and reliability for every rider running a 100mm up to a 250mm dropper post, all with improved battery clearance.
REVERB AXS: EFFORTLESS CONTROL, ANYTIME, ANYWHERE.
Mountain bikers adjust their seat height constantly throughout a ride, and Reverb AXS keeps this action fast and effortless. Powered by AXS Technology, the customization of controllers gives riders a seamless on-trail experience by integrating shifting and dropper functions, making them extensions of the rider. Reverb AXS is as easy to install as it is to remove, with simple maintenance that ensures more time spent riding.
TRAVELS YOU WANT.
Built for GX, X0, and XX riders, Reverb AXS ensures smooth control and reliability for every rider running a 100mm up to a 250mm dropper post in 25mm increments, all with improved battery clearance. Reverb AXS offers exceptional value, bringing wireless, dropper technology to an even broader range of riders
BUILT TOUGH. EASY TO MAINTAIN.
The new Reverb AXS features an air-over-air design that is very robust and easy to service. Its battery placement allows for quick disassembly without special tools. This efficient design is supported by a complete portfolio of replacement parts, including upper tubes, piston assembly, lower tubes, seat clamp, electronic modules, and inner base assembly. Designed for long-term performance, Reverb AXS requires standard lubrication every 300 hours of ride time (approximately 1 year).
DEMYSTIFYING AIR-OVER-AIR.
At top out, the air-over-air design puts the rider atop a specially designed air spring chamber, with virtually no negative air spring. This delivers a firm and supportive platform for the rider. Once the valve is activated and the post moves into its travel, ActiveRide is engaged. ActiveRide introduces a negative air chamber that balances pressure with the positive chamber, enabling enhanced comfort and control during technical climbs.
