XTR M9250-GS Di2 Wireless Upgrade Kit - I-Spec EV Shifter

The Shimano XTR Di2 12-Speed Upgrade Kit is the most advanced wireless drivetrain Shimano has ever created - designed for elite XC racers and enduro riders who demand instant, flawless shifting in the harshest conditions. From race day precision to rugged trail reliability, this Di2 kit delivers unmatched performance.

At the heart is the XTR M9250-GS Rear Derailleur, built with a medium cage, wide-link construction, carbon fiber pulley cage, and an impact-deflecting profile. It features Shimano’s Automatic Impact Recovery, which returns the derailleur to its position after a hit, and Shadow ES design for a low-profile, rock-glancing shape.

Paired with the XTR M9250-IR I-SPEC EV Wireless Shifter, this system offers intuitive ergonomics with a familiar feel and extensive adjustability. Customize your shifting experience with multiple modes—single, double, or multi-shift - plus a programmable third button via Shimano’s E-TUBE Project app.
