Its Time to Replace Your Cassette

Pedaling, shifting, and the rough road you travel on your bike will gradually wear down your bike's chain and sprocket.

Pedaling, shifting, and the rough road you travel on your bike will gradually wear down your bike’s chain and sprocket. The chain stretches and so the shape of the teeth of your cassette gear changes, so that they become sharper and the planes between them larger.

This causes a gradual deterioration in gearshift performance, as a result of which your gears may slip. You will also see changes in the shape of the teeth of the chain, but because there are more teeth in the chain in contact with the chain, the results may not be as obvious. On the other hand, chains are often more expensive to replace than cassettes, so you should try to reduce chain wear.

We have a guide on how to CHECK CHAIN WARE; usually when it’s 0.75 percent worn, it’s time to change your chain. You should also replace your cassette at the same time, otherwise the quality of the tape change may become worse.

Of course, the derailleur works with a variety of cassette sizes, so you might also want to swap out your cassette for a wider or narrower gear range, or maybe you just bought some shiny new wheels.
