Shimano XTR M9250 Di2 Drivetrain Upgrade Kit

 The all-new XTR M9250 long-cage derailleur paired with a standard 10-51T M9200 cassette gives riders and racers the speed, range, and robustness to tackle every trail on the mountain. With built-in Automatic Crash Recovery, an impact-deflecting shape, and simple covered-pulley solutions, this derailleur stands up to harsh trail impacts and still retains its lightning-quick shifting speed and top-level performance.

 

Optimized for impact survivability, the 12-speed mid-cage M9250 rear derailleur is the choice for both Shimano’s top enduro athletes and weight-conscious XC racers alike, especially when matched with the 9-45 compact cassette. Featuring all-new wireless Di2 shifting, automatic impact recovery, a redesigned wedge shape and 23 millimeters of additional ground clearance for a bash-free ride, this rear derailleur stands out for the speed of its shift and its ability to keep riders competitive on the trail.
