Abstract
A transmission chain, particularly for a bicycle, has inner links alternated to outer links. The inner and outer links are constituted by pairs of plates articulated to each other by means of pins. The plates of the inner links have their outer surfaces with a depressed central portion. The plates of the outer links have their inner surfaces with a depressed central portion. The plates of the outer links further have through holes for engagement of the articulation pins with enlarged end mouths opening on the outer surfaces of these plates, which receive the riveted ends of the articulation pins.
