SRAM XX 10 Speed Rear Mech

XX was a global effort. Working across ten locations in six countries with an amazing team of engineers and designers, we collaborated to build the new standard of lightweight MTB performance. Driven and tested by our global teams of athletes, XX became a reality.

XX was an idea whose time was right: our first MTB group. We didn’t just want to be better—we wanted to be beyond comparison. Revolutionary front shifting, unmatched ergonomics, and unequalled hydraulic remote suspension lock-out, all in the first-ever 2x10 MTB package. But don’t take our word for it. Hear what our elite test athletes and tech support has to say.

The Continuation of the SRAM Legacy. Leveraging the legendary history of SRAM shifting, the XX Rear Derailleur delivers incredible speed and precision. Sealed ceramic pulleys give you the highest levels of durability. The carbon fiber cage has a dedicated length specific to 2x10. Exact Actuation technology eliminates slop and shifting variation. It’s a rear derailleur perfected for ultimate off-road performance.

Precision equals consistency equals victory. XX uses the Exact Actuation shifting technology developed for SRAM road to help give you the ultimate MTB shifting experience. Exact Actuation delivers an identical 3mm adjustment between each gear on the cassette, replacing the typical slop found between gears with a crisp, clean, and immediate shift. This consistent, precise adjustment means smoother, faster, and better shifting with no variation in pull effort from gear to gear.
