CC-4 Chain Checker

Product Information

The Park Tool CC-4 Chain Checker is an essential tool for maintaining your bike's drivetrain health. This drop-in style gauge accurately measures chain wear, helping you determine the optimal time for replacement. By strategically contacting a long section of the chain in three places, the laser-cut CC-4 takes the guesswork out of assessing chain stretch. Timely chain replacement prevents poor shifting and prolongs the life of more expensive drivetrain components like your cassette and chainrings.
