SRAM XX Eagle T-Type XS-1297 12-Speed Cassette

The XX Eagle T-Type 12-Speed 10-52t cassette is a major reason why Eagle Transmission offers one of the best-ever inboard and outboard shifting performance under load. Thanks to its full X-Sync design, the harder you pedal, the better it shifts. Literally. Engineered as integrated and interdependent transmission components, the XX Eagle Transmission Cassette and derailleur contact directly, ensuring perfect alignment on every bike.
