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.
