Checking your bike chain for wear is a breeze with the Pedro's Chain Checker Plus II. This essential tool helps cyclists maintain top - notch drivetrain performance and cut down on maintenance costs. It quickly and easily checks for 0.5% and 0.75% chain wear. Thanks to its three - point design, it accurately measures pin and roller wear, unlike two - point designs that can give false readings. This means you'll get the most out of your chain. The Chain Checker Plus II also comes with a chain hook tool for hassle - free chain removal and installation, and a chainring nut wrench for chainring work. It's compatible with 1 - 12 speed chains and is SRAM - approved for use on EAGLE 12 - speed chains.

Using the Pedro's Chain Checker Plus II is super easy. First, find a straight part of your chain and insert the tool into the chain. Check the markings on the tool to see if your chain has 0.5% or 0.75% wear. If it does, it might be time to replace the chain. When using the chain hook tool, just hook it onto the chain and pull to remove or install the chain. For the chainring nut wrench, simply fit it onto the chainring nut and turn to remove or install the chainring. Remember to keep the tool clean after each use. You can use a dry cloth to wipe off any dirt or grease. Store it in a dry place to prevent rusting. Also, always double - check your measurements to ensure accurate results.
