Before diving into the buying process, I found it crucial to understand what a chain tensioner does. Essentially, it keeps the chain taut, preventing it from slipping off the gears. A well-adjusted chain tensioner ensures that your bike runs efficiently, which means fewer maintenance issues and a more enjoyable ride.
