10. Inspect The Chain And Sprockets

Chain Wear Check

First, you should inspect the sprockets. A worn sprocket will take its crooked teeth and chow down on your shiny new chain. So, look closely at the sprockets. Are the sides of the teeth worn? If so, expect to find a matching wear pattern on the inside of the chain. Do the teeth of the sprockets look like cresting waves? Are teeth — gasp — missing? If you answered yes to any of these questions, you definitely need new sprockets. At the very least, should change an aluminum rear sprocket with every new chain. The soft aluminum tends to wear more quickly than the OE steel sprockets. However, if your aluminum sprocket is hard anodized, it should withstand a couple of chain replacements.
