A worn chain shifts poorly and wears sprockets at an accelerated rate. The CC-3.2 Park Tool Chain Wear Indicator 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. The updated CC-3.2 is longer, more accurate and features permanent measurement markings. Works on all 1/2" pitch chain, from 1- to 11-speed.
