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.
- Effortless Electronic-Wireless actuation and infinite height adjustment with a single touch.
- Clean, simple and fast to install. No hoses to route, no fishing required.
- Updated internals for faster return speed in all conditions.
- New Vent Valve Technology, a simple and reliable built in service solution without disassembly of the seatpost.
- SRAM AXS technology, a new level of interaction, personalization, and connectivity across all AXS-enabled components.
