Shimano RD-M9250 XTR Di2 12 Speed Rear Derailleur

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.

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. 

• 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.
