Your bike chain, cassette and chainrings will all wear out eventually, but how do you know when to change them? Here's our guide.

A newly minted drivetrain makes your bike feel great, and keeping on top of chain wear and old parts on your bike will make for cheaper repalcements as our chain wears faster than the cassette and chainrings.

Measuring chain stretch or wear can be done with a specifc tool, a ruler or just by pulling the chain.

Chainrings generally last a long while - and the tell tales sign is "shark's teeth". The cassette is similar - "shark's teeth" or "ghost shifting" just after you've changed your chain.

Making sure you change your chain, cassette and chainrings as they wear will ultimately make your riding cost less, so get measuring your chain now!
