The RockShox Reverb AXS B1 Dropper Post is a redesigned version of the ever-popular Reverb AXS Dropper, refined for increased durability, better support, and a smoother ride—all with AXS technology to incorporate it into your bike’s AXS ecosystem. The Reverb B1 features a new air-over-air design that’s easier than ever to service, with a specially designed air spring chamber for a firm and supportive pedaling platform when the post is fully extended. Once the Reverb is actuated and compressed, the ActiveRide technology is engaged, balancing pressure between the negative and positive air chambers to subtly smooth out the ride, for a more compliant pedaling platform. Designed with serviceability, affordability, and compatibility in mind, the new Reverb AXS is the dropper post for every rider.
