Super Reds are expertly designed to be some of the best bearings on the market. Super Reds aren't just REDS with a better finish. 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. REDS and Super REDS not only differentiate in style but quality.
