Reverb AXS B2 Wireless Dropper Post

The RockShox Reverb AXS B2 Dropper Post raises the bar for wireless performance with a tougher, more refined design and improved on-trail functionality. Built around an updated air-over-air internals system, the B2 delivers increased durability and consistency compared to previous Reverb AXS generations, it’s ready for everything from daily rides to aggressive trail use.

One of the standout updates is ActiveRide technology, which introduces built-in compliance when the post is in a partially dropped position. That means added comfort and traction on technical climbs, while still offering a firm, fully extended position when you need maximum pedaling efficiency. It’s a subtle but game-changing feature that enhances control on unpredictable terrain.

The collar-mounted battery not only keeps the system clean and easy to access, but also improves tire clearance, especially useful on modern bikes with tighter frame designs and longer travel. Like all AXS components, actuation is completely wireless, delivering fast, precise adjustments at the push of a button (AXS controller sold separately).

Designed for versatility, the Reverb AXS B2 is compatible with a wide range of saddle rail standards, making it easy to integrate into almost any setup.
