Good chain maintenance is essential to keep your gears running and changing smoothly, so as your chain stretches over time, it’s a good idea to check if yours has stretched too far. This easy to use LifeLine tool will clearly show when it’s time for a chain change on your bike, possibly preventing you encountering a snapped chain when you’re out for a ride.
The industry standard for chain replacement is when the chain wear is between 0.75% and 1.0%. Simply place one end into a link on your chain and if the 0.75% side fits in your chain will soon need replacing, if the 1.0% side fits in it's time to replace it immediately.
