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. Vent Valve Technology for super simple service if the need arises without any disassembly of the post NEW Lower friction IFP allows for faster actuation of the post and less force needed AXS™ Technology allowing for customization to an individual rider’s liking via the AXS™ Mobile App Includes AXS™ handlebar controller and battery Shared battery with all other SRAM AXS™ enabled components System is completely water and dustproof to IP69K SPECIFICATIONSPost diameter: 30.9 mm, 31.6 mm, 34.9 mmTravel: 100 mm, 125 mm, 150 mm, 170 mmPost length: 340 mm, 390 mm, 440 mm, 480 mmRemote: Included
