Shimano XTR Di2 M9250 Wireless 12 Spd MTB Rear Derailleur

GS (For 9-45T Cassettes): 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 millimetres 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.

SGS (For 10-51T Cassettes): 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.

• 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.
• SHIMANO SHADOW ES: A slimmer, stronger evolution of Shimano’s pioneering chain-stabilizing Shadow concept.
• Precise & Clean Wireless Shifting: Wireless Di2 paired with HYPERGLIDE+ technology result in smooth, precise and instantaneous shifts.
• 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.
