STANDARD CYCLE CHAIN

Most bicycles use cycle chains to transmit power from chain rings to the rear wheels.  Cycle chains can be categorized into two types:

1/2" pitch x 1/8" width or 3/16" width:
Used for simple transmission without derailleur gear.

1/2" pitch x 3/32" width:
Used for both simple transmission as well as transmission with derailleur gear.

In additional to bicycles, these chains can also function in other transmission operations used for, for example, agricultural equipment or electric garage doors, etc.
