The Shimano Inner Plate GS-Type is a genuine replacement part designed specifically for Shimano rear derailleurs that use a GS (medium cage) configuration. As part of the derailleur cage assembly, the inner plate plays a crucial role in guiding the chain smoothly across the cassette, helping to maintain crisp, reliable shifting under load. Using an original Shimano inner plate ensures precise fit and alignment, which is essential for consistent performance and long-term durability of your drivetrain.
This inner plate is ideal for riders who want to restore the performance of a worn or damaged derailleur cage without replacing the entire derailleur. Whether you ride on the road, gravel, or trails, a straight, properly shaped inner plate helps reduce chain noise, improve chain retention, and minimize unwanted friction. By choosing an authentic Shimano GS-Type inner plate, you can confidently service your derailleur, extend its lifespan, and keep your bike shifting as the manufacturer intended.
