Robust. Resilient. Ready for Anything - The Shimano XTR Di2 12-Speed Upgrade Kit provides riders with the pinnacle of wireless MTB shifting technology. The kit features an all-new XTR M9250 Di2 wireless rear derailleur that's optimized for impact survivability to make it the choice for both Shimano's top enduro athletes and weight-conscious XC racers alike. 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 wireless shifting speed and top-level performance. 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 precision, while a tunable third button allows for additional system tuning or third-party connection. Kit includes an XTR M9250 Di2 wireless derailleur, XTR SW-M9250 Rapid ES wireless shifter, BT-DN320 Battery, EC-DN100 Charger, and Quick Link.
