XX1 Eagle AXS 12-Speed Rear Derailleur

What Our Gearhead® Experts Are Saying:

"For competitive XC and marathon riders, the XX1 Eagle AXS shifts are just faster, and the carbon build keeps bikes light without losing any reliability. Overload clutch and app customization are nice touches for rough days and dialing setup pre-race."

XX1 Eagle AXS 12-Speed Rear Derailleur represents the next generation of MTB shifting—designed for elite XC racers and trail riders demanding flawless, wireless control. The carbon fiber cage and titanium hardware maintain a svelte profile without sacrificing strength, while the slightly forward and inboard positioning gives extra chain wrap and up to 10mm more ground clearance than mechanical competitors. The AXS platform brings total customization, allowing users to alter shift logic, check battery status, and synchronize with AXS-equipped Reverb droppers using the easy mobile app. When disaster nearly strikes, the Overload Clutch disengages the electronic motor to absorb hits, instantly resetting so you can finish the race. Rain, mud, and dust are no match for the IP69K sealed system, and battery swaps are a breeze—simply pop off the power cell, plug it into USB, or swap with a spare. Compatibility with standard Eagles chains, cassettes, and shifters (including analog up front) makes this the centerpiece for dream builds and podium pursuits.
