RD-M8120 Inner Plate SGS
The Shimano RD-M8120 Inner Plate SGS is a replacement component for Shimano Deore XT 12-speed rear derailleurs. This inner plate forms the structural foundation for the derailleur's parallelogram mechanism and pivot points, made from aluminum for durability. Precision manufacturing supports proper alignment and smooth cage movement throughout the cassette range.
This SGS (Super Long Cage) inner plate suits the wider gear ratios found in modern mountain bike drivetrains. The component holds the tolerances required for Shimano's Shadow RD+ clutch mechanism and cage stabilization system. Installation calls for careful attention to torque specifications and pivot alignment to restore reliable shifting performance.
