Bicycle Cassette Replacement

소개

The cassette on your bicycle can get worn down over time. With regular use of the bicycle, including continuous pedaling and shifting, the cassette wears down which then causes wear on the chain and performance issues for the entire bicycle. This excessive chain wear can cause further damage to the chain rings, which can lead to the entire drivetrain of the bicycle needing replacement. To avoid this from happening, replacing a worn down cassette is beneficial as it can extend the lifespan of a drivetrain and lead to a more enjoyable biking experience. This guide will show you step by step how to replace the cassette on any 7-12 speed bicycle.

Before starting this guide make sure that you detach the rear wheel of the bicycle that holds the cassette. Also make sure to have all necessary tools listed in the guide.
