Shimano Derailleur RDM8250 Rear Deore XT 12 Speed DI2 10-51T

Features:

• Wireless electronic derailleurs for tackling everything from XC MTB racing and everyday trail riding to blitzing technical enduro courses
• Robust skid-plate design with a wide link structure incorporates a durable aluminum plate and solid pulley for outstanding reliability and longevity
• Shielding pulley cage design prevents trail debris from jamming up and potentially stopping the moving pulley and chain
• RD Protection Function returns the derailleur to its original position after an impact
• Shadow ES evolves chain stabilization with a slimmer, stronger iteration
• Wedge Shape adds an additional 23mm of ground clearance and deflects impacts from rocks or trail debris
• Mid-Cage GS option optimizes the use of a smaller chainring with a 9-45T cassette for a lighter and more compact drivetrain configuration that adds even more clearance
• Battery tucks safely within an enclosed space for total security and is easily removed when it is time to be recharged
