Rear derailleur 1x12-speed Shimano XT RD-M8100-12-GS SHADOW RD+ Rear Derailleur XT series, ideal for smooth and precise shifting, suitable for mtb use.

The new SHADOW RD gear mechanism is designed for more aggressive riding. Its excellent low-profile design brings many benefits. Due to the slender design and uniform tension, the gear mechanism stays closer to the gear system, avoiding hits in difficult riding conditions. The result is smooth and quiet performance.
