The XTR Di2 drivetrain kit combines the all-new XTR M9250-SGS long-cage derailleur with the M8250 SHIMANO RAPID ES shifter, BT-DN320 battery, and EC-EN100 charger. The 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. The shifter feels instantly natural out of the box, but can also be moulded to fit any hand, thanks to its familiar fit and evolved adjustability design. Available with either I-SPEC EV compatibility or band clamp mounting options depending on your setup requirements.
