The XT rear derailleur RD-M8000 by Shimano - easier to use

The Shimano XT RD-M8000 rear derailleur features a Shadow Plus mechanism that allows you to switch between maximum chain stability and minimum operating forces. The extremely low profile and shallow angle of attack are also beneficial for safety on difficult, narrow trails. In addition, the RD-M8000 is better at handling a slanted chain than its predecessors and has larger derailleur pulley teeth for even smoother shifting performance. In the Dyna-Sys11 system, it thus performs its service efficiently and consistently. Both cages of the rear derailleur are made of lightweight aluminium. In the shorter version (GS) it is compatible with 1x11 and 2x11 systems and cassettes up to 46 and 42 teeth respectively. In the long version (SGS) it can also be used for 3x11 drivetrains with an 11-40 cassette.

The real advantage of 11-speed is the ability to have all the range you require without sacrificing the rhythm you need. Dyna-Sys11 maximizes rhythm while driving and climbing with " Rhythm Step" gears in the most frequently used range. Driving efficiency is a key drivetrain performance indicator. Dyna-Sys11 means more speed for the same effort.

Less distraction, quiet drivetrain. Rear derailleur stabilizer, reduces chain slap. Simple solution for chain drop. Lighter and more efficient than roller type chain device.
