| Park Tool CC-3.2 Chain Wear Indicator |
 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-speed chains, replace as the 0.5% side fits. The CC-3.2 is long, accurate and features permanent measurement markings. Shipping Weight: .25 lbs. Price: 9.86 |
