The chain ring is the circular disc that forms part of your crankset. As you pedal the crank will rotate the chain ring. The teeth on the chain ring should be spaced to fit into and engage every link of the chain as it passes through the chain ring. This process converts the power generated from pedalling to the rear wheel and gets you moving.
