Obviously the width of the bicycle chain must be somewhat wider than the thickness of the chainrings and cogs or sprockets. A typical bicycle chain comes in two widths: 1/8 (3.175mm) The standard width of a bicycle chain for BMX riders and also the older one and three speed bikes. 3/32 (2.38mm) width The standard for all modern multi-speed bicycles. These chains are commonly referred to as derailleur chains, thus any bicycle that uses a derailleur to shift gears.
