SunRace MZ90 12-Speed MTB Cassette 11-50T | Ultimate Wide-Range Upgrade
Unleash the full potential of your mountain bike with the SunRace MZ90 12-Speed Cassette. Designed for the demanding world of MTB cycling, this cassette is the ultimate upgrade for riders seeking a massive gear range, reliable performance, and exceptional value. Whether you´re tackling grueling climbs that seem to go on forever or sprinting on fast, flowing singletrack, the MZ90 provides the perfect gear for every situation, transforming your ride experience and boosting your confidence on the trail.
This cassette is engineered to be a game-changer for your 1x drivetrain setup, offering an expansive range that eliminates the need for a front derailleur while ensuring you´re never over or under-geared.
Key Benefits:
* Conquer Any Terrain: With its enormous 11-50T gear range, the MZ90 empowers you to winch up the steepest technical ascents with an easy-spinning cadence, thanks to the massive 50-tooth climbing gear. On the other end, the 11-tooth cog provides the top-end speed you need for fast descents and flat-out pedaling sections, giving you unparalleled versatility.
* Seamless & Cost-Effective Upgrade: One of the standout benefits of the SunRace MZ90 is its compatibility with traditional Shimano HG freehub bodies. This means you can upgrade your bike to a modern, wide-range 12-speed system without the extra cost or hassle of purchasing a new wheelset or swapping to a different freehub driver (like XD or Micro Spline).
* Optimized Lightweight Performance: Every gram counts in MTB cycling. The MZ90 features lightweight, anodized red aluminium spider arms, a spacer, and a lockring. Crucially, the two largest sprockets (42T and 50T) are crafted from high-strength, lightweight 7075 T6 aluminium. This intelligent design reduces rotational weight where it matters most, improving your bike´s acceleration, climbing efficiency, and overall handling.
* Crisp and Reliable Shifting: SunRace´s advanced tooth profiling and ramp design ensure smooth, crisp, and precise gear changes, even when you´re shifting under load during a challenging climb. You can count on the MZ90 to deliver the gear you need, exactly when you need it, for a frustration-free ride.
