The Shimano Deore XT group has proven time and again that it is engineered for performance and reliability. The Deore XT RD-M8120 12-speed Rear Derailleur is no different. 13T pulley wheels increase chain wrap for smooth and efficient shifting while the bumper on the pulley cage keeps things silent in rough terrain. Shadow Plus is a low-profile design that keeps the derailleur tucked close to the bike and tensions the drivetrain to eliminate chain slap and dropped chains.
