XTR M9250 Rear Derailleur

What Our Gearhead® Experts Are Saying:

"I like this for aggressive trail and enduro riding where durability really matters. The wireless shifting is super fast and precise, and the auto-recovery feature is huge—it keeps you riding even after a hit. It’s light, tough, and just feels dialed when things get rough."

We trust the XTR M9250 Rear Derailleur when the trail turns rough and every shift counts. Shimano engineered this derailleur for riders pushing limits in enduro stages and XC sprints, giving us lightning-fast wireless shifting with the confidence to keep charging through rock gardens and technical descents.

At the heart of it is Shimano’s Di2 wireless system paired with HYPERGLIDE+, delivering seamless, instant gear changes under load. The SHADOW ES design stabilizes the chain while increasing ground clearance, helping avoid strikes and maintain control in unpredictable terrain. When impacts do happen, the auto-recovery system quickly resets the derailleur so we can stay focused on the ride.

A carbon cage, reinforced pulley system, and integrated skid plate add durability without unnecessary weight, while compatibility with both 9–45T and 10–51T cassettes gives us flexibility to build the perfect drivetrain. Built for performance and survivability, this derailleur is ready for the most demanding rides.
