Shimano Deore XT Di2 Rear Derailleur Long Cage 12s RD-M8250-SGS

The all-new DEORE XT M8250 long-cage derailleur paired with a standard 10-51T M8200 cassette gives all types of riders the range and robustness to tackle every trail on the mountain. With built-in Automatic Impact Recovery, a new, impact-deflecting wedge shape, and simple covered-pulley solutions, this derailleur stands up to harsh trail impacts and still retains its lightning-quick shifting speed and high level of performance.

Features

Robust Design: A wide link structure, skid-plate design, durable aluminum 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 RD+ concept.

Precise & Clean Wireless Shifting: Ultra-fast shifting and a no-sacrifice 500% gear range.

Protected Battery: Tucked safely inside an enclosed space, the battery won't budge even in rough terrain, while remaining easily removable for charging.

Covered Pulleys/Cage: The solid pulley and shielded pulley teeth prevent trail debris from jamming up your flow.
