Sunrace CSMX9X 11 Speed XD Drive Cassette

The SunRace MX9X is an 11-speed cassette that is designed to be the perfect solution for riders that don’t want to resort to an expensive expander sprocket – and want a smooth, clean shift between gears. Featuring “Fluid Drive Plus” technology, it ensures each cog works with its neighbour to optimise shifting performance. The XD-Drive design of the cassette means SunRace can use a smaller 10T cog to increase the gear range and improve top speed. This makes it perfect as a replacement cassette for 11-speed SRAM drivetrains or for use with SunRace’s own 11-speed groupset.
