The Shimano XT M8250 Di2 Wireless Upgrade Kit gives you everything you need to take your existing Shimano 12-speed mountain bike into the wireless future.
Optimized for impact survivability, the RD-M8250 rear derailleur is the top choice for everyday trail riding, offering unmatched durability and quick, precise shifts. Featuring all-new wireless Di2 shifting, automatic impact recovery, and 23 millimeters of additional ground clearance for a bash-free ride, the M8250 rear derailleur is built to be relentlessly reliable so you are free to focus solely on the trail ahead. Get added weight savings and quicker shifting when pairing the mid-cage with Shimano's 9-45T compact cassette or get the range and robustness to tackle every trail on the mountain pairing the long-cage with a standard 10-51T.
The SW-M8250 Di2 Wireless 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 and 2-step multi-shift, offer versatility and precision, while the tactile click prevents mis-shifts and a tunable third button allows for additional system tuning or third-party connection.
