XS-797 T-Type Downhill 7-Speed Cassette

What Our Gearhead® Experts Are Saying:

"I’ve sprinted out of the gate on this cassette and never had to back off to get a clean shift. The 7-speed range keeps ratios tight, and the T-Type design holds the chain solid under load. If you’re racing downhill, this is built for exactly that job."

When the clock starts and we’re driving every watt into the pedals, we don’t want to think about shifting—we just want it to happen. The XX Downhill AXS Transmission Cassette is built for that moment, delivering seamless shifts under full load so we never have to ease off the throttle between features.

Its optimized 7-speed 10-24T range keeps gear steps tight for gravity racing, helping us stay in the power band from start hut to finish line. The full X-SYNC tooth profile maintains constant chain engagement, working in lockstep with T-Type chains and AXS-driven cassette mapping to preserve momentum during every shift. Available in XD and XD SLIM variants to match hub standards, it integrates cleanly into modern downhill builds while maximizing clearance and wheel strength. This is downhill-specific gearing designed to move fast and stay composed under pressure.
