XS-797 T-Type Downhill 7-Speed Cassette

What Our Gearhead® Experts Are Saying:

"The first thing you notice is how tight and direct the gearing feels. The 10-24T spread keeps shifts small and fast, and you can shift at full sprint without losing momentum. Just make sure you match the correct XD or XD SLIM driver—there’s no cross compatibility."

Downhill racing demands acceleration without interruption. The XX Downhill AXS Transmission Cassette is engineered around a 7-speed 10-24T configuration that prioritizes tight gear steps and sustained power delivery. Designed specifically for gravity riding, it allows riders to shift under full load without sacrificing speed, maintaining continuous chain engagement through SRAM’s T-Type architecture.

The full X-SYNC tooth profile optimizes inboard and outboard shifting performance while improving chain retention in rough terrain. Integrated with AXS firmware-driven cassette mapping, it keeps the chain engaged during gear changes to preserve forward momentum. The cassette is available in both standard XD and gravity-focused XD SLIM variants, each requiring the matching driver body with no cross compatibility. The XD SLIM option enables improved spoke bracing angles and enhanced heel clearance on 148mm rear ends. Purpose-built for the XX DH Transmission system and compatible exclusively with T-Type chains, this cassette delivers precise alignment, faster shift intervals, and uninterrupted power transfer for riders chasing every possible millisecond.
