The M9050 XTR Di2 E-tube Rear Derailleur is compatible with Shimano Di2 11-speed groupsets, and is best suited to mountain bikes and other off-road applications. The GS Medium Cage can carry your chain between the sprockets of a rear cassette ranging from 11T to 42T (2x11-speed) or 46T (1x11-speed).
Constructed with sealed pulley bearings, this is a hard wearing derailleur with an inner structure that is protected from strong impacts. Either mount it conventionally or with the newer direct mount standard and enjoy flawless shifting all day long, on any trail or path.
A mixture of carbon fibre and aluminium pulley plates balance weight-saving and durability. Specifically designed to work with the XTR M9000 11-speed Dyna-Sys drivetrain.
