Keep chain wear in check

The Park Tool CC-4.2 Chain Checker accurately measures a long section of chain and comes in contact with the chain in three places, taking the guesswork out of judging chain wear.

The tool works on any 5 to 13-speed chain or single-speed chain and is designed to indicate when a chain reaches 0.5%, 0.75%, and 1.0% wear.
