A bicycle chain is a chain that transfers power from the pedals to the drive-wheel of a bicycle thus propelling it.


The chain in use on modern bicycles is a roller chain with a 1/2" pitch. Chain comes in either 5/32", 1/8", 3/32" or 3/16" roller widths: 5/32" is used on cargo bikes and trikes, 1/8" with the common low cost coaster (back pedal brake) bike, hub and fixed gearing and on track bicycles, and 3/32" with the derailleur gears most commonly fitted on racing, touring and mountain bikes.
