    ParkTool CC-4 | Chain Checker

    R319.90

    The CC-4 is a drop-in style gauge that measures bicycle chain wear. The laser-cut CC-4 accurately measures a long section of chain and strategically comes in contact with the chain in three places, quickly and easily taking the guesswork out of knowing when chain replacement is necessary. A worn chain will cause poor shifting as well as accelerate drivetrain wear. The tool works on any 5 to 12-speed derailleur chain (including SRAM® AXS®) and is designed to accurately indicate when a chain reaches .5% and .75% wear, the points at which most chain manufacturers suggest replacement.

  • ParkTool CC-3.2 Chain Checker

    ParkTool CC-3.2 | Chain Checker

    R219.90

    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% “stretch,” the points at which most chain manufacturers suggest replacement. For 9 and 10-speed chains, replace the chain just as the gauge fits the 0.75% side fits flat into the chain. For 11 and 12-speed chains, replace the 0.5% side fits. The CC-3.2 is long, accurate, and features permanent measurement markings.
