How to determine the wear level of a cassette?

This question comes up quite often, but unfortunately there's no magic answer. In fact, the cassettes cassettes have no wear indicator, and the design of the teeth, which differs from brand to brand, makes it difficult to create a tool to check wear.

Nevertheless, we're going to try and help you by looking at the different methods available to judge wear:

  1. The first is as simple as it is obvious: gears are unstable when the material is too worn. If you've just replaced your chain and the rest of your drivetrain is in good condition, but the gears aren't shifting properly, then there's no doubt that the cassette needs replacing.

  2. The second requires a bit of an eye. Look at the shape of the teeth on a new cassette, and you'll see that almost all of them end with a more or less bevelled tip. If the teeth of your cassette are worn to the point of ending in a point, it's high time to replace it.

  3. The third is a manufacturer's recommendation: replace the cassette every two chains.

For chain and chainring wear, we invite you to consult the relevant aids.
