The RD-M8050 rear derailleur retain the accurate and stable shifting developed for XTR Di2 components.

The technology to change your ride: Shimano XT Di2 11-speed Rear Derailleur RD-M8050 GS Shadow+
Computer-controlled auto trim on the front derailleur keeps the drivetrain running smoothly. Meanwhile, at the rear, changes are seamless, even under high loads, on steep inclines or when cassettes are more mud than teeth. The derailleur motors are twice as powerful as those on Dura-Ace and Ultegra Di2 to give precise shifting in difficult conditions.

Battery performance is identical to that of its big brother, XTR Di2, giving a minimum of several hundred kilometres of power under heavy usage (eg lots of shifting over three chainrings plus control of ancillary devices). The visual LED display indicates battery charge and the LED screen shuts off after a few seconds of inactivity to save battery life. If you do find yourself running low, charging the battery takes around 90 minutes and internal batteries work on a simple plug and play operation so can be easily swapped.

Durability is also in line with XTR Di2 components. A sealed, waterproof system means DEORE XT Di2’s electronic signals will stand up to mud, water and dirt from the worst of winter. Plus, with no worrying about cross-chaining, cable stretch, or cable adjustments, your gear changes will be incredibly consistent.
