The DEORE XT M8100 series of derailleurs offers an enhanced level of drivetrain silence, achieved by reducing tension in the low gear position and adding a bumper to the pulley cage. The larger 13T pulleys improve efficiency and chain management, while compatibility with SHIMANO's new 12-speed cassettes increases range.
