ROCKSHOX Reverb AXS Dropper Post 2025

RockShox Reverb AXS 2025 Dropper Post – Wireless MTB Dropper Post

RockShox has released the completely redesigned Reverb AXS dropper post for 2025, offering an even longer travel, improved construction, and wireless operation. ​

Key features:

• Travel and sizes: The new Reverb AXS is available with travel options of 100 mm, 125 mm, 150 mm, 175 mm, 200 mm, 225 mm, and 250 mm, making it the dropper post with the longest travel on the market. Diameter options are 30.9 mm, 31.6 mm, and 34.9 mm. ​

• Air-Over-Air construction: The post's fully air-powered "air-over-air" construction improves durability and makes maintenance easier. This design also enables ActiveRide™ functionality, which provides suspension at the saddle, improving comfort and control on technical climbs. ​

• Wireless AXS integration: The Reverb AXS integrates seamlessly into SRAM's AXS ecosystem, enabling wireless control and simplifying bike handling. A shared battery and charger with other AXS components reduce cabling and complexity. ​

• Improved battery placement: Moving the battery and control unit closer to the seatpost collar reduces the risk of contact with the rear wheel and improves the battery's protection from dirt and moisture. ​

• Compatibility: The post is compatible with all AXS controls, but does not support wireless Blip buttons or communicate with the Flight Attendant suspension adjustment system. ​

The redesigned RockShox Reverb AXS offers top-tier performance and comfort for mountain bikers who value long travel, wireless functionality, and easy maintenance.​
