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.
