    What is the function of a cassette on a bicycle?



    A cassette consists of several sprockets which are fixed on a freewheel, they are driven by a chain. The cassette is one of the items used to vary the gear ratio or reduction ratio of the drivetrain so that the speed of rotation of the rear wheel varies. Lower the number of teeth of the sprocket driven by the chain, greater the speed of rotation of the wheel will be. The number of gears on a bicycle is given by the number of sprockets on the cassette multiplied by the number of chainrings.Generally a cassette is made up of 5 to 12 speeds.
