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.

The wireless-electronic Reverb AXS is all Reverb, revamped with a controller you touch instead of a lever you throw. No second guessing. No delay. A refreshingly light touch of the controller's paddle offers instant engagement. A simple press of the paddle sends it down. Hit it again, it's right back up. The perfect speed. Its infinite range lets you set it right where you need it, saving you time, energy, and keeping your focus on the trail ahead.

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.

We don't want you to have to use it, which is why we've created the most robust seatpost to date. We also know, sometimes the inevitable happens. Over time, air and oil may mix, resulting in that annoying post 'squish and the need for additional service. Vent Valve Technology allows you to do this simple service within a few steps, without any disassembly of the post. Depress the valve, compress the post, good to go. The air is channeled back into the air chamber leaving the oil where it belongs and you back to more confident reliable performance.
