The RockShox Reverb AXS A2 Dropper Seatpost features Vent Valve Technology for simple service without requiring disassembly of the post. The lower friction IFP allows for faster actuation and requires less force to operate. This seatpost is AXS enabled, allowing for customization to individual rider preferences via the AXS Mobile App. The package includes a battery and charger. An SRAM AXS handlebar controller is sold separately and can be paired with AXS drop bar shifters, POD controller, or other compatible components.
