XX Downhill XS-797 T-Type Cassette - For XD Driver

SRAM XX Downhill XS-797 T-Type Cassette is a DH-specific 7-speed cassette built for racers who need clean, predictable shifts while putting down big power. With tight 10–24t gearing and a full X-Sync tooth profile, it’s tuned to keep cadence changes small when accelerating out of corners, sprinting between compressions, or dropping gears on steep starts—without the “soft pedal” habit that costs time.

This version fits the widely used XD driver and is compatible only with T-Type chains (sold separately), making it a purpose-built match for SRAM Transmission DH setups where durability and shifting under load matter most.

Race-day details that matter

1. 7-speed DH-only range (10–24t) - Tight gear steps help maintain momentum and cadence control on high-speed tracks
2. Full X-Sync tooth profile - Designed for precise inboard/outboard shifts and strong chain engagement under power
3. Shifting under load - Supports confident gear changes while pedaling hard, reducing the need to back off in critical sections
4. Included Setup Cog - Streamlines installation and helps dial in the system correctly the first time
5. XD driver interface - Broad hub compatibility for straightforward wheel and freehub pairing
