Lube the Chain Before It Squeaks
Squeaking sounds when you're pedaling indicate unnecessary wear and tear on your drivetrain and the noise almost always comes from a dry chain. If you look at the chain and see bright, shiny links, you've waited too long to add lube. Always try to keep a thin film of lube on the chain and you'll prevent rust, squeaks, poor shifting and premature drivetrain wear. Lubing the chain like this is one of the easiest bicycle repairs you can perform!
