SunRace MZ600 12-Speed MTB Cassette with 11-51T Wide Range - Shimano HG-M Fit
The SunRace MZ600 12-Speed 11-51T Cassette is a high-performance wide-range MTB cassette designed for modern 1x12 mountain bike drivetrains. Featuring an expansive 11-51 tooth gear range, this 12-speed cassette delivers exceptional climbing capability, smooth indexing and durable construction for aggressive trail riding, enduro and all-mountain use.
Engineered with Shimano HG-M (MTB) freehub compatibility, the MZ600 cassette fits standard Hyperglide mountain bike freehub bodies, making it an ideal upgrade or replacement option for riders seeking wide-range gearing without changing their rear hub. The massive 51T large sprocket provides ultra-low climbing gears for steep technical ascents, while the 11T high gear ensures efficient speed on flats and descents.
SunRace’s Fluid Drive+ technology optimises tooth profiling and shift ramps for smoother, more precise gear changes under load. Precision-engineered steel cogs deliver strength and wear resistance for high-torque riding, while the alloy lockring keeps weight down and ensures secure installation.
Finished in sleek black, the SunRace MZ600 12-speed cassette combines durability, wide-range performance and reliable shifting, making it a strong choice for trail riders, enduro racers and mountain bikers upgrading to a 12-speed drivetrain system.
The SunRace MZ600 features a 12-speed configuration with an 11-51T gear range, Shimano HG-M (MTB) freehub compatibility, Fluid Drive+ indexed shifting, durable steel sprockets and a lightweight alloy lockring.
