How to check if you should change your chain kit?

If you want to use your chain kit as long as possible, it is important to regularly check and maintain the components on your MX or enduro bike. The wear of chain, front und rear sprocket can't be avoided and is individual in the respective parts. The wear is influenced by your riding style, weather conditions and the ground on which you ride regularly.

So how do you know if you should change the chain, front or rear sprocket? With a chain gauge you can check if your chain has extended and a replacement is necessary. This method is more accurate than pulling off individual chain links on the rear sprocket to determine the lengthening of the chain. Another indicator are deformed teeth on the front sprocket as well as the rear sprocket. The typical shark tooth shape of the front sprocket occurs because the teeth on the sprocket are worn unevenly over time. When you notice one of the described indicators on your drivetrain components, you should change your chain, front and rear sprocket as soon as possible. Because these components become worn together, they should be replaced at the same time.
