The Park Chain wear tool CC 3.2 is an easy to use tool that quickly and accurately tells you when your chain is due for replacement due to wear. A worn chain shifts poorly and wears sprockets at an accelerated rate.
Simply place the tool on your chain between the rear wheel and front crank run. The “go-no go” gauge will accurately indicate when a chain reaches .5% and .75%, the points at which most chain manufacturers suggest replacement. The newer updated Park Chain wear tool CC 3.2 is longer, more accurate and features permanent measurement markings.
