NEW Shimano XTR RD-M9250-SGS Di2 Wireless Rear Derailleur - 12-Speed, Shadow ES, Black/Gray

The Shimano Di2 XTR M9250 wireless long cage derailleur paired with a standard 10-51t M9200 cassette (cassette sold separately) 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 XTR RD-M9250 medium cage rear derailleur is the choice for both Shimano’s top enduro athletes and weight-conscious XC racers alike, especially when matched with the 9-45t compact cassette (cassette sold separately). 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.
