Please also note that we highly recommend fitting a new chain with your cassette. This is because chains and cassettes wear sympathetically with each other.
Our cassettes are manufactured with fine tolerances, therefore if you do not change your chain, there is a chance issues may arise such as shifting and noise.  To remedy this we recommended fitting a new chain and cassette at the same time.
