PROX CHAIN LINK X-RING 520MXR RIVET TYPE

ProX has developed a premium line of Roller Chains to team up together with the ProX front and rear sprockets. This is a high quality chain manufactured exclusively for ProX. The MX chains are assembled out of various different components that all have their specific and crucial function to make the chain a high quality product. Pins do feature an exclusive pin treatment providing an extremely hard outside coating, leaving a softer inside to increase strength while reducing overall chain wear. The pins are heavy press fitted and do feature quad staked riveting for ultra-strong connection. The solid bush inside the shot-peened, solid roller and plates are all heat treated to offer an incredible tensile strength in combination with low friction and high wear resistance. Inner plates are designed in a specific shape allowing less material to be used which in combination with the unique lightning holes results in a 3% overall lighter chain without compromising tensile strength. All ProX chains are pre-stressed and pre-stretched to reduce initial chain stretch and immediate performance and come with a clip type chain link as standard.
