Shimano RD-M9250 XTR DI2 Rear Derailleur - Silver

The all-new XTR M9250 rear derailleur is available in both mid-cage and long-cage configurations. The mid-cage version is optimised for impact survivability and 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. The 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. Both feature all-new wireless Di2 shifting, automatic impact recovery, a redesigned wedge shape and additional ground clearance for a bash-free ride. These rear derailleurs stand out for the speed of their shift and their ability to keep riders competitive on the trail, with built-in Automatic Crash Recovery, an impact-deflecting shape, and simple covered-pulley solutions that stand up to harsh trail impacts while retaining lightning-quick shifting speed and top-level performance.

Features

• Robust design - a wide link structure, skid-plate design, durable carbon plate and solid pulley add robustness and longevity
• RD protection function - a new automatic impact recovery function instantly returns the derailleur motor to its original position after impact

• Wedge shape - the new wedge shape of Shimano's most survivable rear derailleur to-date avoids more direct impacts, and smoothly glances off rocks if there is a hit
• Protected battery - tucked safely inside an enclosed space, the battery won't budge even in rough terrain, while remaining completely removable for charging
