Whether you are assembling a new bicycle or your chain has succumbed to chain stretch, changing out or installing a chain can be an intimidating, dirty job if you don't know what you are doing. Luckily, the process is very straightforward. Let's dive in!
First, we have to understand the basic nature of a bike chain. It consists of a repeating set of links connected by rivets (also known as pins). Over time, the holes through which the chain rivets pass can elongate due to the strain of powerful pedaling stokes. This is called "chain stretch" and can make your chain slip while shifting or when pedaling powerfully.
