The SRAM XX DH Transmission XS 797 cassette is built for downhill racing, where every shift counts. Its tight 7-speed 10 to 24T range keeps cadence steady for hard accelerations, while the full X Sync tooth profile delivers secure chain control and smooth shifting under load. Designed to handle full power sprints without backing off, it gives riders the confidence to shift exactly when needed. Available in XD and XD SLIM options to match different hub standards.
