Super REDStm are designed from the ground up to be the
best bearing on the market at this price point.
What Super REDStm are not is a bearing with just better super finishing
(surface polishing) Super REDStm 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 REDStm but quieter,
smoother, and longer lasting!
