Checking your bicycle chain wear is crucial in ensuring safety and preventing damage to your sprocket. It also improves your chain shifting experience. This chain wear indicator can allow you to check the bicycle chain wear and is easy to use. If the indicator shows wear above 0.75%, it is recommended to change a chain. If it shows above 1%, you should change your chain. If both ends of the chain checker cannot be placed into the chain gap at the same time, it means that the wear is within normal range. If both ends fit easily, you should change your chain too.
