Competetive gravity riders rejoice at the X01 DH XG-795 7 Speed Cassette thanks to SRAM's ditching of excess cogs for that optimal spread. From the 10T small to the 24T large the gears jump an even two teeth providing consistent changes rather than the variable spread of traditional cassettes. The X01 DH Cassette is only compatible with XD driver wheels and the Mini-Block X-Dome technology works with all SRAM 1X drivetrains. The dome is machined from steel with a durable JET black coating to ensure it's ready for anything a World Cup circuit can bring to the table.
