    Know the State of Your Chain.

    The easiest way to ensure that your shifting is the best it can be and prevent unnecessary wear on the rest of your drivetrain is ensuring that your chain is not excessively worn. Park Tool offers the CC-3.2 which is by far the easiest to use chain wear measuring tool that is so quick to use we should all be embarrassed at how little we check our chain's wear. The CC-3.2 is a go/no-go gauge that accurately indicates when chain wear reaches 0.5 and 0.75-percent, the points where most manufacturers suggest replacement. Simply put the end of the chain checker in the chain and see if you can place the permanent measuring marked ends into the chain links. For 1 through 10-speed chains, replace it if the gauge on the 0.75-percent side fits into the links. For 11 and 12-speed chains, replace when the 0.5% side fits. The CC-3.2 will quickly save you from frustration and money.

    Great tool to have

    • Familiarity: I've used it several times

    This tool helps keep your chain in check and drivetrain running smoothly. Definitely a must have for the home mechanic or even the occasional rider. Plus you can’t go wrong with park tool.

    You Need This in Your Toolbox

    • Familiarity: I've put it through the wringer

    This is a necessary tool. Keep an eye on your chain and the rest of your drivetrain will last longer. This is the tool I used daily as a mechanic - a general rule of thumb for 11s chains is if the 0.5% side drops in, replace your chain, if the 0.75% drops in there's a good chance you'll need to replace the cassette too.

    The 4 star rating is because Shimano's chain checker is more accurate due to the way it preloads the links in both directions, but it's also way more expensive.

    Check your chain often!

    • Familiarity: I've used it several times

    If you're putting in the miles, you need to be using this tool all the time. The more you use it to check chain wear, the more money you save in the future by avoiding wearing your whole drive train down. This is a must have tool.
