CONTEC cassette sprocket "Grad"

Enjoy better ride quality for longer with our Grad cassettes. We make no compromises in terms of function and durability, thanks to the weight and wear-optimised material mix used in our cassettes: While the largest and heaviest sprockets are made of aluminium to save weight, the smaller sprockets are made of particularly hight tensile steel to better withstand the greater torques that are applied to the fewer teeth. As a result, our Grad cassettes offer increased durability compared to conventional sprocket sets, from which you benefit through higher mileage (i.e. longer maintenance intervals) and longer superior shifting performance. Our Grad cassettes have special climbing aids for the chain that make each of your gear changes faster and smoother, so you don't have to think about shifting but can concentrate fully on riding. This cassette is suitable for 12-speed gears and has a 10-50 teeth.The CONTEC Grad cassette sprocket is now also suitable for a Micro Spline mount.
