The SRAM XS-1275 GX Eagle Transmission 12-Speed Cassette is engineered to deliver exceptional shifting performance under load. Its full X-SYNC design ensures that the harder you pedal, the smoother it shifts. Designed for a 55mm chainline, it reduces chain angles throughout the gear range, enhancing precision and extending component longevity. The cassette offers a 520% gear range with a 10-52 tooth configuration, featuring optimized gear steps in the lower range for improved climbing efficiency. Constructed with a combination of Pindome and MINI-CLUSTER technologies, it balances durability with weight savings.
