The Sram XX SL Eagle is a power-measuring crankset designed for 12-speed MTB drivetrains. Its hollow carbon fiber arms offer exceptional stiffness and very low weight. This design allows the creation of a crankset with the highest performance, appreciated by riders who enjoy trail riding and weekend racing. The completely new power measurement located in the spider enables precise training or performance monitoring with an accuracy of +/- 1.5%. It uses an innovative bolt-on chainring system, providing maximum stiffness without adding unnecessary weight. The T-Type tooth profile works perfectly with the chains, offering reliability and smoothness in all conditions. The DUB Wide spindle offers excellent features and broad compatibility with frames. Eagle Transmission technology revolutionizes mountain bike drivetrains. The completely redesigned mechanisms are built around a universal fixed core—the spindle. This solution requires almost no adjustment while offering exceptional speed and precision, even under maximum load. The suspension-free freehub support system significantly improves impact resistance. T-Type items bearing this symbol offer full compatibility with each other, allowing parts mixing between groups without concerns about performance or proper function. The DUB is a modern spindle standard, with a diameter of 28.99 mm, providing greater stiffness and simplicity. An additional advantage is its compatibility with any frame by selecting the appropriate bottom bracket.
