Shimano XTR Di2 RD-M9250-GS Med Cage (GS) 12 Speed Rear Derailleur use w/ 9-45 Cassette

Shimano XTR Di2 RD-M9250-SGS 12-Speed Medium Cage Rear Derailleur (for use with the new 12 speed 9-45 cassette)
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 mm 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.
• Robust Design: A wide link structure, skid-plate design, durable carbon plate and solid pulley add robustness and longevity.
• RD Protection Function: The new Automatic Impact Recovery function instantly returns the derailleur 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 shifting.
• 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
