SRAM's family of companies have all been engaged to some degree for the ultimate gravel experience, including RockShox provide the Rudy XPLR series suspension forks, as well as this Reverb AXS XPLR Dropper Seatpost for those who seek comfort and control during the most versatile gravel and adventure experiences. Enabled by SRAM AXS technology, Reverb AXS XPLR is part of the ultimate personalized cockpit system and can be controlled via road or mountain wireless AXS control systems, while personalization of the dropper functions is set-up via the AXS Mobile App. No wires or hydraulic hoses to deal with here- just the clean, immediate and secure application of AXS technologies with a superior dropper design from the masters of bike suspension components.

The Reverb AXS XPLR dropper post delivers more control, confidence, and fun on gravel roads everywhere. Getting the saddle out of the way by lowering it quickly means more room for the rider to move, saving said rider from awkward maneuvering and sketchy descents. RockShok's engineers created an all-new design complete with lightweight Air-only internals featuring built-in compliance dubbed ActiveRide™. The Air-only internals provide a fully rigid top-out position and keep weight as low as possible. With the touch of your AXS controller, you’ve got built-in compliance to ensure comfort and control over the roughest sections of gravel. For bikes that require a 400mm post overall, both 50 and 75 mm travel models are offered. For those bikes, generally smaller frame sizes, a 350mm max length post is offered, but only in the 50mm travel version. All current models of the Reverb AXS XPLR are made with a 27.2mm round diameter size. The same eTap AXS battery used throughout AXS road and mountain groups is included, as is a charging dock and USB cable. For good measure, you can rest easy on those water crossings as the system is completely waterproof and dustproof to IP69K. Drop your saddle to raise your game when the terrain gets roughest with RockShox.
