Shimano Deore Di2 RD-M6250 Rear Derailleur Description:

The Shimano Deore Di2 RD-M6250 Rear Derailleur features a design that offers incredible wireless shifting performance and better clearance over trail obstacles with improved survival odds if an impact unfortunately occurs. The derailleur body incorporate a skid-plate design with a durable steel plate that helps deflect strikes, a wide link structure for enhanced drivetrain stability, and a pulley cage that shields solid pulleys to prevent debris from jamming up the moving components. A revolutionary wedge shape adds considerable clearance that helps to avoid and/or deflect impacts, and an integrated RD Protection function instantly returns the derailleur to its original position after impact. Shadow ES chain stabilization is an evolution of the original Shadow chain stabilization system, and has been developed in part to create the lower profile at the leading edge of the derailleur while maintaining strong chain retention and reduced chain slap on the chainstays when hitting rough terrain. As for the shifting, lightning quick and very precise shifts happen at the moment the Di2 Shift Switches are actuated, with the rear derailleur effortlessly gliding the chain up and down the HYPERGLIDE+ cassettes. Last but not least, the long cage design enables the use of a 10-51T cassette for a robust 510% effective gear range that allows a rider to be able to hold their own over the most demanding, technical terrain.

Note: Rear derailleur does not include the XT Di2 Battery.
