Most bikes used nowadays have a gear changing system that facilitates the cyclist's effort. Through the gear shifters whch can be found on the handlebars, the chain's position both on the chainrings and the cassette sprockets can be changed in order to improve performance when cycling uphill or downhill.
In order to ensure the cassette of your bike is kept in the best condition, is very important to use lubes so that the friction of the chain with the teeth of the chainrings and cassette sprockets does not end up damaging the material. If these components are not greased regularly they will end up wearing out and their lifespan will be much shorter.
How to choose the cassette for your bicycle?
When we talk about the cassette , we are referring to the complete cluster of cassette sprockets, which is slotted onto the freehub body on the rear of your bike. The cassettes can be composed of 7 to 10 sprockets. The classification used for the cassettes reflects only the number of teeth of the smallest and largest sprockets. For example, in a normal mountain bike cassette the classification would be 11/32, which refers to a 9-speed sprocket, since it is composed of a small sprocket of 11 teeth, then one of 12, one of 16, of 18, of 21, of 24, of 28 and finally a large sprocket of 32 teeth. This said, in road bikes, the cassettes can have more sprockets, which can allow for more speeds.
