The Details

The all-new Shimano DEORE XT M8100 series of derailleurs brings a new level of drivetrain silence thanks to decreased tension in the low gear position and an added bumper on the pulley cage.

Larger 13T pulleys increase efficiency and chain management while compatibility with SHIMANO's new 12-speed cassettes boosts range.

Shadow plus technology offers a super low profile design and optimized slant angle for super light shifting action. Shadow plus also features a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting.

 

  • Single tension spring prevents contact with the chainstay resulting in a silent ride
  • Rubber bumper on pulley cage for added silent drive
  • 13T pulleys and decreased derailleur tension prevent high chain tension in low gears
  • Specifically designed to work with 12-speed 1x drivetrains
  • Max low sprocket: 51T (1x 12-speed)
  • 41T capacity SGS cage

Our Verdict

The new Shimano XT Shadow plus 12-speed rear derailleur offers fast and precise shifting performance and has been optimized to take on any trail.
