BikeMaster 520×120 BMXR O-Ring Chain – Pink

Ideal O.E.M. replacement offering 1.5 to 2x longer wear resistance than regular O-ring chains. Each refined component, designed with computer analysis, provides higher tensile strength. Specially controlled heat treatment means tougher material and more durability. Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and endurance. Q4 seal ring offers less friction, which minimizes power loss, almost half that of standard O-ring chain. Note: This chain must be correctly matched to the machine size and power output. Failure to do so could result in chain failure, causing machine or property damage, serious injury or death. It is the responsibility of the installer to ensure that the chain selected is correctly matched to the machine and installed correctly. If you have any doubts, contact a professional before use.
