SRAM XS-797 T-Type 7-Speed Cassette Smaller steps, quicker shifts, faster descents. The SRAM XS-797 DH-specific cassette is built for riders who keep their foot on the gas on the biggest descents. Designed with tight, DH-specific gear steps, the XS-797 7-Speed Cassette keeps cadence changes small while accelerating out of corners and dropping in at top speeds. A full X-Sync tooth profile boosts shifting performance both up and down the cassette range, even when shifting under load. Like the rest of the SRAM Transmission ecosystem, it's made to work seamlessly with T-Type components for consistent chain engagement and dependable shifts with unbeatable durability. Choose XD or the gravity-specific XD SLIM driver option to match your hub and optimize spoke bracing angles on narrow 148mm rear ends. Features Full X-Sync Tooth Profile for best-ever shifting performance under load, both inboard and outboard DH-specific 7-speed gear range with tight 10-24t steps for faster cadence control and stronger acceleration Under-load shifting designed to perform when you're pedaling hard, not backing off SRAM Transmission specific built exclusively for SRAM T-Type/Transmission chains and drivetrains Driver Options available in XD or gravity-specific XD SLIM hub interfaces to suit different hub dimensions SPECIFICATIONSSpeeds (Cassette)7Gear Range10-24t Cog Sizes10, 12, 14, 16, 18, 21, 24Drivetrain Configuration1x Chain Technology T-Type Only Driver Body Compatibility XD or XD SLIM (variant-dependent) | Sram | Xs-797 T-Type 7 Speed Cassette 10-24 Xd
