PARK TOOL CC-3.2C Chain Wear Indicator

The PARK TOOL CC-3.2C chain wear indicator provides a quick and simple way to check the degree of wear on your chain, in order to maintain smooth transmission and extend the life of your chainring(s) and cassette.

This tool features two wear indicators, at 0.5% and 0.75%. For 9- and 10-speed chains, it is recommended to replace the chain when the 0.75% threshold is reached. For 11- and 12-speed chains, manufacturers recommend replacing it at 0.5% wear.
