The Shimano XT RD-M8000-GS Rear Derailleur is a top-performing mountain bike component designed for 11-speed drivetrains. It features a medium cage and black color, as well as a clutch mechanism that helps to reduce chain slap and dropped chains. The derailleur has a maximum capacity of 46 teeth for 1x11 drivetrains, 42 teeth for 2x11, and 40 teeth for 3x11, ensuring smooth and reliable shifting. The low profile design of the cage minimizes the collection of debris, which helps to protect the derailleur from damage. The clutch is externally adjustable, making it easy to fine-tune the spring tension. Additionally, the optimized slant angle of the derailleur reduces shift effort while improving shifting and driving stability. The RD-M8000-GS is compatible with Shimano mountain bike shifters and has a chain wrap capacity of 39 teeth. It weighs 271 grams.
