Park Tool Chain Wear Indicator for Cyclists CC-3.2

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. This tool quickly checks chain stretch and wear, and it will determine if a chain is good or bad. The updated CC-3.2 is longer, more accurate, and features permanent measurement markings. Made from precision, laser-cut steel, it fits derailleur and one-speed chains, including 9 and 10-speed.

The condition of a chain is crucial for the overall performance and longevity of a bicycle's drivetrain. A worn chain not only shifts poorly but also accelerates the wear on the sprockets, leading to increased maintenance and potentially more frequent component replacements. To address this issue, the CC-3.2 gauge is designed to provide a reliable and accurate assessment of chain wear.

Developed by chain manufacturers, the CC-3.2 is a go-no go gauge that allows users to quickly determine if a chain has reached the recommended replacement thresholds of .5% and .75% wear. This is a critical point, as most chain manufacturers suggest replacing the chain at these stages to ensure optimal performance and prevent excessive wear on other drivetrain components.

The updated version of the CC-3.2 gauge features several improvements over its predecessor. It is now longer, providing a more accurate measurement of chain wear, and the markings are permanently etched onto the tool, ensuring they remain visible and legible over time. This tool is designed to quickly and effectively check the chain's stretch and wear, giving the user a clear indication of whether the chain is in good condition or needs to be replaced.

Crafted from precision, laser-cut steel, the CC-3.2 gauge is built to withstand the demands of everyday use. Its durable construction ensures long-lasting reliability, making it a valuable tool for both professional mechanics and cycling enthusiasts alike. The gauge is compatible with a wide range of chains, including those used in derailleur and one-speed systems, as well as the increasingly popular 9 and 10-speed configurations.

In summary, the CC-3.2 chain gauge is an essential tool for maintaining the health and performance of a bicycle's drivetrain. Its accurate and easy-to-use design, combined with its durable construction, makes it a must-have item for anyone who values the longevity and efficiency of their bicycle.
