How to replace your chain

A worn chain reduces efficiency and accelerates wear on your drivetrain. Regularly measure your chain to know when it’s time for a replacement. This can extend the life of your cassette.
How to replace your chain?
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..
