A properly lubricated, Heavy-Duty racing non-”O”-ring chain will perform efficiently as long as there is a “lubricating oil boundary layer” between critical bearing surfaces. However, once the boundary layer dissipates from high speed running, lack of maintenance, or simply over time, the inner bearing surfaces will overheat, kink, cause severe drag, and ultimately fail. RK “O”-ring chains prevent this from happening by continuously lubricating and protecting critical internal bearing surfaces.
