Super REDS™ are designed from the ground up to be the best bearing on the market at this price point. What Super REDS™ are not is a REDS™ bearing with just better super finishing (surface polishing). Super REDS™ are a superior quality bearing,using higher quality steel races,better quality and grade balls,and a superior surface finish. The result is a bearing that is as fast as REDS™ but quieter,smoother,and longer lasting. Super REDS™ use a black shield and laser engraving to differentiate themselves from original REDS™.
