How to determine the wear level of a platter?

This question comes up often enough to try and answer it, but unfortunately there's no magic answer. In fact, the chainrings don't have wear indicators, and the different tooth designs of different brands make it difficult to create a tool for monitoring wear.

Here are a few ways to judge the wear of your chainring


For chainring wear chain and cassetteWe invite you to consult the relevant help pages.

  • The first is as simple as it is obvious: gears are unstable when the equipment is too worn. If you've just replaced your chain/cassette set and your front derailleur is in good condition, but the chainrings don't shift properly: no doubt about it, the chainrings need replacing.
  • The second requires a new chain. Place the chain on the chainring, pull on the chain, and at the highest point you must not be able to reveal more than half the chainring tooth.
  • Finally, the manufacturers' recommendation: every 2 chains, replace the cassette. And, every 2 cassettes, replace the chainrings. This is not true for a single-plate transmission.
