The SunRace MZ800 12 speed cassette is a high quality wide range cassette designed to deliver smooth, reliable shifting for modern mountain bike and gravel drivetrains. Offering an impressive 11 to 51 tooth gear range, it provides the low climbing gears needed for steep technical terrain while maintaining efficient gearing for faster sections.

Designed to work with Shimano 12 speed transmissions, the MZ800 is fully compatible with Shimano SLX, XT and XTR 12 speed drivetrains while fitting a standard Shimano HG freehub body. This makes it an excellent option for riders looking to retain their existing HG freehub without upgrading to Microspline.
