Description
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. The updated CC-3.2 is longer, more accurate and features permanent measurement markings.
