Rock Shox: 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.THINGS TO REMEMBERNEW Features Vent Valve Technology for super simple service if the need arises without any disassembly of the postNEW Lower friction IFP allows for faster actuation of the post and less force neededAXS™ Technology allowing for customization to an individual rider’s liking via the AXS™ Mobile AppIncludes AXS™ handlebar controller and batteryShared battery with all other SRAM AXS™ enabled componentsSystem is completely water and dust proof to IP69K SPECIFICATIONSPost diameter: 30.9mm, 31.6mm, 34.9mmTravel: 100mm, 125mm, 150mm, 170mmPost length: 340mm, 390mm, 440mm, 480mmRemote: Included
