XTR Di2 REAR DERAILLEUR LONG CAGE 12s

RD-M9250-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 Impact 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.

FEATURE

• 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.
