XTR M9250 Upgrade Kit

Mid Cage GS: 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 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. Long Cage SGS: 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. Shifter: The XTR M9250 SHIMANO RAPID ES shifter feels instantly natural out of the box, but can also be molded to fit any hand, thanks to its familiar fit and evolved adjustability design. Multiple shift modes, like hold-down multi-shift, tactile click-through double shift, or locked-out single shift, deliver top precision, while a tunable third button allows for additional system tuning or third-party connection. DERAILLEUR 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. SHIFTER FEATURES: Ergonomic Evolution: Familiar fit and multi-axis adjustability make this Shimano’s most natural-feeling shifter yet. Fast Action: Precise, lightning-quick wireless shifting activated by Shimano’s most adjustable, customizable, and satisfyingly tactile shifting switch. Finely Tuned: Assign a function to the programmable third button through the E-tube app, with full switch and e-bike customization. Feature Rich: Tech-packed, with a four-way adjust, two-step double shift or hold down multi-shift, rubber traction pad, I-SPEC EV clamp band and single/double mode converter.
