Get the right tools
You only need a chain wear measurement tool—a small investment that saves money over time. Look for one that measures 0.5% wear or less
Measure the wear
Replace your chain as soon as it reaches the 0.5% wear mark. Competitive cyclists may want to replace theirs sooner, as a worn chain significantly impacts performance. You start losing 1 watt after just 0.2% wear..
