The Shimano Rd-M8150 Deore Xt Di2 rear derailleur is a quick and smooth shifting system designed for E-bikes. It features programmed automatic motion at the touch of a switch, making it effortless to shift. The removal of traditional mechanical cables in favor of electrical wires eliminates poor shifting caused by contaminants, corrosion, and stretching. The derailleur contains a saver function, where the inner structure is protected from strong impacts. It also features aluminium pulley plates for weight saving and durability. The M8150 is specifically designed to work with 12-speed cassette and drivetrain, and is 12-speed E-tube Di2 compatible. It has a max low sprocket of 51T and a total capacity of 41T.

Love the product. Smoothest shifting, easiest time indexing gears I've ever had once you read the user's manual. Free shift is good, but auto shift brakes chains and in some cases deraileurs.
