How does the Park Tool CC-2 measure chain wear?

The Park Tool CC-2 Chain Wear Indicator takes the guesswork out of chain replacement by giving you a definitive go/no-go reading in seconds. The precision-machined gauge drops into chain links at a calibrated depth: if the tool seats fully, your chain has stretched past the wear threshold and needs to be replaced before it accelerates cassette and chainring wear.

Built from hardened steel for lasting accuracy, the CC-2 provides a simple, repeatable measurement that takes the subjective judgment out of chain service decisions. Catching a worn chain early is one of the most cost-effective things you can do for drivetrain longevity, and the CC-2 makes that check fast enough that there's no reason to skip it.

FAQ

How do I use the CC-2 Chain Wear Indicator?

Place the CC-2 into the chain links on the lower run of your chain. If the gauge seats fully at the wear mark, the chain is worn and should be replaced. If it does not seat fully, the chain still has usable life.

What speed chains does the CC-2 work with?

The CC-2 is compatible with standard roller bicycle chains across 5- through 12-speed drivetrains on road, gravel, and mountain bikes.

Why does chain wear matter for the rest of my drivetrain?

A stretched chain wears cassette cogs and chainrings faster than normal. Replacing the chain at the correct interval protects these more expensive components and maintains clean, reliable shifting.

Best For

Mechanics and cyclists who want a simple, accurate tool for checking chain wear before it causes costly cassette and chainring damage on any road, gravel, or mountain drivetrain.
