How Bike Chain Works

How to Find a Master Link on a Bike Chain: The Easy and Quick Method

A bike chain consists of different links, both wide and narrow, in a pattern throughout the length of the chain. On each link, you see two side plates, and these are connected to each other by rivets or pins. The links will also fit into slots on the sprockets, and there is a roller on the outer link.

When riding your bike, the chain is wrapped around the sprockets and will move. It provides the force that moves your bike while you pedal. The chain rub links go against the sprocket teeth when you pedal, causing it to rotate. This turns the crank in effect and will spin the wheels. If you are looking for a new bike, consider buying one of the best road bikes under $500.

Another function of the chain is to transfer power to the rear wheel from the pedals. This is why the chain must not be loose, or it can slip off the sprockets. The derailleur is what keeps the chain tight; this is a part of the bike that transitions the chain between sprockets.
