The Shimano XT M8250 Di2 Wireless Upgrade Kit brings your 12-speed mountain bike drivetrain into the future with fast, reliable wireless shifting and impact-ready durability. Designed to meet the needs of trail and enduro riders, this upgrade kit includes everything needed to convert to Shimano’s latest Di2 system.

At the core is the RD-M8250 rear derailleur, built with a wide-link design, solid pulley construction, and 23 mm of added ground clearance for improved impact protection. Shimano’s new Automatic Impact Recovery function helps maintain performance after crashes by resetting the derailleur’s position instantly. Whether you opt for the mid-cage with a 9-45T cassette for a lighter setup or the long-cage with a 10-51T cassette for maximum range, the M8250 delivers precise, stable shifting you can trust on any terrain.

The SW-M8250 Di2 shifter offers a familiar feel with improved adjustability thanks to Shimano’s I-SPEC EV mounting system. It features a responsive tactile click, customizable shift modes including multi-shift options, and a programmable third button for added control via Shimano’s E-TUBE PROJECT app.

This upgrade kit includes the derailleur, shifter, internal battery, charger, and a 12-speed quick link, making it a complete solution for riders ready to experience wireless shifting at its best.
