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.Cutting out the cables makes set up fast and easy. No external hoses. No internal routing. No energy wasted. The Reverb AXS™ complete wireless design is fast to install, and easy to pair. Complimented with an all-new post head, the turn of a single rail-retention bolt makes for a quick and effortless saddle install. Make it perfect with one additional bolt at the front of the head for tilt-adjust and position lock. Drop it in, and send it down.Tucked neatly into the back of its post head, the Reverb AXS™ uses the same rechargeable SRAM battery found on the Eagle AXS™ derailleur. Easy to remove, and simple to interchange between components if needed. From sun up to sun down, the SRAM battery boosts plenty of ride time (40 hours on trail depending on use) and fully recharges in under an hour. Using an auto-wake sensor, there’s no need to turn it on/off, it’s ready when you are.SRAM AXS™ technology is opening a new door to a connected experience with your bike. Connecting components to software. Enabling the wireless RockShox AXS™ controller to talk instantly to the Reverb AXS™ seatpost. Connectivity across multiple AXS™ enabled components all supported through the new SRAM AXS™ mobile app. Customize AXS™ component configurations, review battery life, track usage, receive rolling firmware updates, and much more via the mobile app. AXS™ technology is the brain, expanding what's possible on a bike.Clean, Simple And Fast To Install: Effortless wireless-electronic actuation and infinite height adjustment with a single touch.
