Maximize your drivetrain’s lifespan by being aware of your chain’s wear and replacing the chain when necessary. Chain wear depends on ride conditions and cleaning habits, so it’s a good idea to learn how to measure for it:
1. Choose an approved chain wear indicator.
2. Install the hooked end of the tool on a link against a roller.
3. Attempt to install the other end of the tool into the chain.
4. If you can insert the tool, the chain is at 0.8% elongation and needs to be replaced.
5. If you can’t insert the tool, the chain is not yet worn enough for replacement.
