Shimano Deore XT RD-M8120-SGS Rear Derailleur

Thanks to lower tension in low gears and an additional buffer on the pulley cage, the completely new Shimano DEORE XT M8100 series of derailleurs offers a high quality silent transmission system. The larger 13D pulleys offer greater efficiency and chain management and are compatible with Shimano’s new 12-speed cassettes.
