Park Tool Chain Checker CC-3.2

Park Tool Chain Checker CC 3 2. A performance and damage saving gauge from Park Tool, the Chain Checker CC 3.2 will help you pinpoint exactly when you should look to change your chain. Accurate and Simple Wear Indicator. A 'gono go' chain wear indicator, the CC 3.2 is an easy to use tool for making sure your chain is in top condition or to let you know when to replace it. One end of the tool hooks in to your chain for stability while the other will either stay supported by the link it reaches if there is no wear, or will fall flush in to the link if wear is found. Set to measure at 0.5% and 0.75% wear, as this is when most manufacturers recommend changing your chain, the Chain Checker CC 3.2 will not only keep on top of your chain's performance, but will also protect your sprockets from any associated wear.
