One of the main reasons that the XX SL Eagle Transmission drivetrain system provides the best shifting characteristics even under load, is the perfectly matched T-Type cassette. The cassette and the rear derailleur of the XX Eagle SL series are designed as integrated and interdependent transmission components that mesh directly with each other to ensure perfect alignment on any bike.
The stronger the rider pedals, the more the Full X-SYNC™ tooth design of the XS-1299 cassette plays out its potential and improves the shifting performance accordingly. With the help of the large 52-tooth sprocket, the 12-speed cassette also achieves a huge gear ratio range of 520 %.
By using an aluminium spider for the three largest sprockets, the XX SL model even becomes SRAM's lightest Eagle cassette to date – without compromising on durability and precision. This is thanks to a lower chain angle across the entire range. But also the X-DOME™ design of the sprocket unit (gear 4 to 12) benefits the durability, while the optimized gear gradation in the lower range provides a smoother shifting behavior.
Features of the SRAM XX Eagle SL Transmission cassette
- Full X-SYNC™ tooth design for the best shifting performance under load and in both directions
- optimized gear jumps in the lower range thanks to the sprockets with 38 and 44 teeth
- tuned to 55 mm chainline for lower chain angle and correspondingly less wear and higher precision
- X-DOME™ architecture with a very light sprocket unit milled from a steel block (10-32 teeth)
- ultra-light aluminium spider for 38, 44 and 52 tooth sprockets
- small sprocket with 10 teeth to extend the gear ratio range
- clearly marked setup cog for a simple and tool-proof assembly
- compatible with XD freewheels
Note: Only compatible with SRAM Eagle Transmission drivetrains and T-Type components only.
X-SYNC™ | The sophisticated tooth design with high, square edges ensures maximum performance and durability. Not only the narrow, sharp tooth profile grips the chain earlier than teeth with the traditional triangular shape, also the rounded chamfer edges support the chain's guidance. In addition, to withstand adverse conditions, X-SYNC™ chainrings are provided with mud-repellent recesses, which protect the links and rollers of the chain from dirt.
X-DOME™ | The one-piece design of the X-DOME™ technology creates incredibly light, precise and robust cassettes. The open design not only repels dirt better, it also gives the component a longer life and smoother shifting performance.
Material:
- sprocket unit (10-32 teeth): steel (milled, hardened)
- sprocket spider (38/44/52 teeth): aluminum
