The all-new 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 features a super low profile design and optimized slant angle for super light shifting action and uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting.

The XT RD-M8100 rear derailleur is compatible with the below models of shifters:
XTR SL-M9100-R / XTR SL-M9100-IR / XT SL-M8100-R / XT-M8100-IR / SLX SL-M7100-R / SLX M7100-IR / Deore SL-M6100-R / Deore SL-M6100-IR
