The new SHIMANO DEORE XT M8100 Series derailleurs achieve a new level of drivetrain quietness thanks to reduced stress on the low gear position and increased damping in the pulley case. Larger 13D pulleys increase efficiency and chain management while compatibility with SHIMANO’s new 12-speed cassettes increases range.
