Park Tool CC2 - Chain Checker

Keep your bike's drivetrain running smoothly and avoid costly component replacements with the Park Tool CC2 Chain Checker. By accurately measuring chain wear, this simple tool helps you identify the exact moment to replace your chain—before it damages your cassette and chainrings. Most manufacturers advise replacement at or before 1% stretch, as even that small amount of elongation can cause poor shifting and uneven drivetrain wear. With the CC2, you can extend the life of your transmission parts and save money in the long run.

- Measures chain stretch with precision to detect 0.5%, 0.75% and 1.0% wear levels

- Simple two-step operation: place the tool on the chain and read the indicator pins

- Durable hardened steel construction for repeated workshop use

- Compact design fits easily in a jersey pocket or toolbox

- Compatible with all standard bicycle chains, including 5- to 12-speed systems

- Eliminates guesswork and ensures timely chain replacement

Take the guesswork out of drivetrain maintenance and keep your rides smooth and efficient.
