Super REDS are designed from the ground up to be the best bearing on the market. In fact, we don't think any other bearing can challenge Super REDS until you get to the Bones Swiss. What Super REDS are not, is just a REDS bearing with better super finishing (surface polishing). Super REDS are a superior quality bearing, using higher quality steel races, better grade balls, and a superior surface finish. The result is a bearing that is as fast as REDS, but quieter, smoother, and longer lasting.
