The holes on the spider arms used for attaching a chainring can have a variety of dimensions, referred to as the bolt circle diameter, commonly abbreviated as BCD. This measurement is sometimes referred to as pitch-circle diameter (PCD).
Cranks designed to mount one or two chainrings will almost always use a single bolt circle diameter. Cranks designed to mount three chainrings will almost always use two different bolt circle diameters; the larger to mount the two outer rings and the smaller to mount the inner ring. Most modern two-chainring cranks use either a 110mm or 130mm bolt circle diameter.
Bolt circle diameters of common cranks:
Single
130, 135, or 144 BCD
Road double
130 BCD (Shimano and others), or 135 (Campagnolo)
Road triple
130/74 BCD (Shimano and others), or 135/74 BCD (Campagnolo)
Compact/touring double
110 BCD or (Campagnolo carbon 4×110/1×113 BCD)
Compact/touring triple
110/74 BCD
Mountain bike (4 arm)
104/64 BCD
Mountain bike (5 arm standard)
110/74 BCD
Mountain bike (5 arm compact)
94/58 BCD
