CONTEC cassette sprocket "Grad"

Enjoy better ride quality for longer with our Grad cassettes. There are no compromises on the function and durability of our cassettes, thanks to a mix of material for weight and wear-optimisation: While the largest and heaviest sprockets are made of aluminum to save weight, the smaller sprockets are made of high tensile steel to better withstand the larger torques, which loads on fewer teeth. Thus, our cassettes offer increased durability compared to conventional sprocket sets. You benefit from this, as it offers you higher mileage (and therefore longer maintenance intervals) as well as superior shifting performance for longer. Our Grad cassettes have special climbing aids for the chain, which make each of your gear changes faster and smoother, so you do not have to think about shifting and can fully concentrate on riding. This cassette is suitable for 8-speed gears and has 11-28 teeth.
