K-CC-3.2

Park Tool CC-3.2 Chain Checker

A worn chain shifts poorly and wears sprockets at an accelerated rate. The CC-3.2 is a go/no-go gauge designed to accurately indicate when a chain reaches .5% and .75%, the points at which most chain manufacturers suggest replacement. For 9 and 10-speed chains, replace chain just as the gauge fits the 0.75% side fits flat into the chain. For 11 and 12-speed chain, replace as the 0.5% side fits. The CC-3.2 is long, accurate and features permanent measurement markings.

 

The CC-3.2 works on all 1/2" pitch chain, from 1 to 12-speed. Check with manufacturer for specific replacement instructions.
