RockShox Reverb AXS B1

The RockShox Reverb AXS B1 dropper post is the successor to the Reverb that was introduced in 2019. Since then, RockShox has adressed a number of issues, which has resulted in a more reliable and robust product. It builds on the well-known AXS platform, and is compatible with the AXS dropper remotes. Please note that it comes with a battery and charger but without a remote control.

With improved air chambers, the B1 version does not spring back after use when the saddle is in the highest position, which is a big improvement to the previous version. All the electronics are now in the seatpost, and the battery has been moved down, making the dropper post more robust and easier to dismount. The battery under the saddle, where it has more clearance, can no longer cause problems with a sprung rear wheel.

ActiveRide Technology
With an enlarged positive pressure chamber, this Reverb dropper post is extra firm when at its highest point and feels like a normal seatpost. When the saddle is lowered slightly to enhance control and balance on rough sections, the dropper post acts as a suspension seatpost.

AXS Technology
Battery run time for this dropper post is around 40 hours; it uses the same batteries as the SRAM AXS drivetrains, and so they can be changed during a ride. If the battery is dead, it only takes an hour to recharge.

Sizing
With many different drop sizes, which is your ideal one? Start by choosing a dropper with the right diameter. Then you will need to choose between different travel (or drop) lengths. A longer drop makes for more control but also adds more weight - your frame must to be able to handle this. To check this, use SRAM's handy Reverb calculator that lets you easily find the right size dropper with two simple measurements.
