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.

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.
