Chain-Wear Indicator

$10.95 USD MSRP SHOWING COLOR:  POLISHED
Product Information

A worn chain shifts poorly and wears sprockets at an accelerated rate. Park Tool's 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.
