The SHIMANO DEORE XT M8100 series of derailleurs brings a new level of drivetrain quiet, 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 12-speed cassettes adds range.
