We make no compromises on functionality and durability, thanks to a material mix in our cassettes optimized for weight and wear: while the largest and heaviest sprockets are made of aluminum to save weight, the smaller sprockets are made of particularly High Tensile steel to better withstand the higher torques applied to the small number of teeth. Our Grad cassettes therefore offer greater durability compared to conventional cassettes, from which you benefit through higher mileage (i.e. longer service intervals) and consistently superior shifting performance. Our Grad cassettes feature special ramping plates for the chain, making all your gears shift faster and smoother, so you don't have to think about shifting and can fully concentrate on cycling. This cassette is suitable for 8-speed gears and has a gradation of 11-28 teeth.
