Chain Checker CC-3.2

The Park Tool CC-3.2 Chain Wear Indicator is a useful tool that allows you to find out how worn your chain is before you need to change it. A worn chain not only shifts poorly and wears down sprockets at an accelerated rate, but it also causes damage to other components of the drive chain. To use the CC-3.2 Chain Wear Indicator, simply insert the tool into the top of the chain and read the measurement. If the chain reaches between 0.75% and 0.5% then the chain is worn or beginning to reach its end and needs to be replaced before other chain components are affected too. - R.K.

Key Features:
