SRAM Reverb AXS Wireless Dropper Seatpost Kit - Lightweight & Adjustable for MTB, Enduro & Trail Biking - Perfect for Mountain Bike Upgrades & Off-Road Adventures

Not a single thing in the way of the experience.

Our intention with Reverb AXS was inventive and pure: No hoses. No routing. No energy wasted. Not a single thing in the way of the experience. We created a reliable wireless electronic dropper post and controller that actuates with drastically less effort and zero distraction. Expanding what's possible on a bike, Reverb AXS is enabled by SRAM AXS technology, a new level of interaction, personalization, and connectivity across all AXS-enabled components.

Note: 

Most Polygon bikes have a seat tube diameter of 30.9mm. If you're unsure, please contact our tech team and they will help you determine the correct size.
