The SRAM Innenkäfig/Schaltrollen X01/X1 is a dedicated replacement inner cage and pulley wheel set designed specifically for SRAM X01 and X1 rear derailleurs. Over time, derailleur cages and jockey wheels are exposed to dirt, impacts, and wear, which can compromise shifting precision and drivetrain efficiency. By replacing these components with original SRAM parts, you restore crisp, reliable shifting performance and help extend the life of your high-end drivetrain. This set is ideal for riders who demand consistent performance on challenging terrain, whether on long climbs, fast descents, or technical singletrack.
Using genuine SRAM replacement parts ensures perfect compatibility with your existing derailleur, maintaining correct chain line, tension, and guide pulley alignment. The pulley wheels are engineered to run smoothly and quietly, helping to reduce friction and improve overall drivetrain feel. Installing a fresh inner cage and pulley set can also reduce chain noise and improve chain retention, especially under load. Whether you are performing routine maintenance or repairing crash damage, the SRAM Innenkäfig/Schaltrollen X01/X1 offers a straightforward way to bring your shifting back to factory-level performance.
