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. Features Higher quality steel races, better quality and grade balls, and a superior surface finish. Single, non-contact, removable rubber shield for easy cleaning and less friction. High speed nylon ball retainer for greater strength and speed. Pre-lubricated with Speed Cream racing lubricant. Skate Rated clearances, tolerances, materials and lubricant provide the best performance and durability possible.
