Seamlessly compatible with Shimano Micro Spline freehubs, this cassette is built for performance and longevity

CONTEC Grad 12-Speed Cassette | 10-50T for MTB & E-Bikes

Unleash the full potential of your mountain bike or E-bike with the CONTEC Grad 12-Speed Cassette. Designed for the ambitious rider who demands reliability, a wide gear range, and smooth performance, this cassette is the ultimate upgrade for your Shimano Micro Spline compatible drivetrain. Whether you´re tackling technical MTB cycling trails or powering up hills on your E-bike, the Grad cassette provides the gearing you need to conquer any terrain with confidence. Experience a new level of control and efficiency on every ride, from epic climbs to fast-paced descents.

The standout benefit of the CONTEC Grad cassette is its expansive 10-50 tooth range. This massive gearing spread ensures you´ll never be left searching for the right gear. The small 10-tooth cog allows you to maintain high speeds on flat sections and downhills without spinning out, while the massive 50-tooth large sprocket provides an incredible climbing gear to help you winch your way up the steepest, most demanding ascents. This versatility makes it the perfect choice for modern MTB cycling, from all-mountain adventures to enduro racing.

Engineered for both performance and longevity, this cassette features an intelligent hybrid construction. An aluminium double spider provides a stiff and lightweight foundation, ensuring precise shifting even under the heavy load of aggressive riding or the increased torque from E-bikes. The largest sprocket is also crafted from lightweight aluminium to reduce overall weight, while the remaining sprockets are made from high-tensile steel to offer exceptional durability and wear resistance where it´s needed most. This smart design achieves a perfect balance between low rotational mass and the robustness required for thousands of miles of hard riding. Seamlessly compatible with Shimano Micro Spline freehub bodies, this cassette offers a hassle-free installation and integrates perfectly into your existing 12-speed setup.
