Designed with high quality materials. One of the most common questions about bearings, is ?What ABEC are those?? but a better question should be, what does ABEC mean? Basically ABEC is a rating system for the tolerances in a bearings. The higher the number, for example ABEC 7, the less the tolerance in the bearing. Having smaller tolerances means that your bearing will spin faster, for longer.
