The Sunrace CSMZ90 is a wide range, 12-speed 11-50T cassette that fits a standard Shimano driver. This means that you don't have to upgrade to a SRAM specific XD driver in order to run an expanded gear range. Fluid Drive Plus tooth design mimics Shimano's Hyperglide ramps and pins to keep shifting smooth and quiet, and a black coating increases durability and longevity of the cogs.
