Regina 428 Pitch ORT Series O-Ring SealedChain 112 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 color to increase wear resistance.

These chains all either meet or exceed manufacturer's OEM specifications for O-Ring chain, and represent a worthwhile upgrade for bikes originally equipped with a plain 428 pitch chain.

The 428ORT chain has an ultimate tensile strength of 22.2KN and weighs in at 1.08Kg/100 links.
