Regina 520 Pitch OROX Series Plain Chain 110 Links. Quality chains: performance, durability and style designed for urban vehicles. Special extended bushings, developed to increase the press-fit into the inner link plates of the chain, ensure a high resistance to chain kinking. All chains are pre-stretched to increase fatigue and made in gold colour to increase wear resistance.

The 520 pitch ORO chain has an ultimate tensile strength of 28.5KN and weighs in at 1.37Kg/100 links.
