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

The XX Eagle Transmission (T-Type) cassette is the main reason why Eagle Transmission offers the best inboard and outboard shifting performance under load. Thanks to the full X-Sync design, the harder you pedal, the better the shifting gets. Literally. Designed as integrated and interdependent drivetrain components, the cassette and the XX Eagle Transmission derailleur come into direct contact, ensuring perfect alignment on every bike. From the huge 520% gear range, the 52-tooth sprocket steps down with better gear progression with 44 and 38-tooth sprockets in the lower range (compared to the 10-52 tooth Eagle transmission cassette). It lasts much longer and offers greater precision thanks to the use of less extreme chain angles across the range. With a clearly marked setup sprocket, installation is simple and foolproof. It uses a hardened steel X-Dome design for the cluster, while the 38T and 44T stamped steel sprockets are attached to the lighter 12th aluminum sprocket. (Spider sprocket)
