Exclusively manufactured for ProX by the reputable and leading Factory factory in Japan. Pins features special treatment providing an extremely hard coating, leaving a softer inside to increase strength while reducing overall chain wear. Pins are heavy press-fitted and have quad staked riveting for ultra-strong connection. Solid-type bush, roller and plates are all heat-treated for incredible tensile strength in combination with low friction and high wear resistance. Inner plates are designed in specific shape and in combination with unique lightening hole resulting in 3% overall lighter chain. X-Ring type chain uses QX-type seal offering 40% less friction and at least 150% increased durability over standard MX chain. All chains are pre-stressed and pre-stretched to reduce initial chain stretch and immediate performance. Chains come with a clip-type chain link as standard. Separate chain links available for each type of chain.
