PARK TOOL CC-3.2C Chain Wear Monitor

The PARK TOOL chain wear monitor CC-3.2C makes it quick and easy to check the degree of wear on your chain, to keep your transmission running smoothly and extend the life of your Chainring(x) and Cassette.

This tool features two wear marks, at 0.5% and 0.75%. For 9- and 10-speed chains, we recommend replacing the chain when the 0.75% threshold is reached. For 11 and 12-speed chains, manufacturers recommend replacement at 0.5% wear.
