Park Chain Checker CC-3.2 / CC-3.2 – Chain Wear Indicator
A chain checker is an essential too for every cyclist and mountainbiker that wants to avoid unecessary wear and expense on their groupset.
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.
