Derailleur cages like the SRAM Schaltwerk Käfig innen XXSL/XX/X0 are essential small parts that keep modern drivetrains running precisely and reliably. This inner cage plate is designed for use with selected SRAM XXSL, XX and X0 rear derailleurs, helping to guide the chain accurately across the cassette. By replacing a worn or damaged cage, you can restore crisp shifting performance, reduce chain noise and improve overall drivetrain efficiency without having to invest in a complete new derailleur.
Ideal for riders who push their bikes hard on demanding terrain, a fresh inner cage helps maintain correct chain tension and alignment, which is especially important on wide-range cassettes and 1x setups. Whether you are rebuilding a race-ready mountain bike or refreshing a well-used trail machine, this SRAM-specific cage ensures proper fit and compatibility with the matching derailleur models. It is a smart workshop spare to have on hand, allowing you to extend the life of your existing components and keep your shifting feeling precise season after season.
