Shimano XTR RD-M9250-GS Di2 Wireless Rear Derailleur - 12-Speed, Medium Cage, Shadow ES, Black/Gray

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.

• Wireless Di2 paired with HYPERGLIDE+ technology result in smooth, precise and instantaneous shifts
• Wide link structure, skid-plate design, durable carbon plate and solid pulley add robustness and longevity
• Automatic Impact Recovery function instantly returns the derailleur motor to its original position after impact
• Shadow ES design provides a slimmer, stronger evolution of Shimano’s pioneering chain-stabilizing Shadow RD+ concept
• 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
• Tucked safely inside an enclosed space, the battery won’t budge even in rough terrain, while remaining completely removable for charging
