Shimano XTR Di2 RD-M9250-SGS Long Cage Rear Derailleur 12 Speed

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.
