As a rider owned shop, it really bother me how gimmicky the bearings in our industry are. I hated ordering junk generic bearings that costs extra just because a brand put their name and promote their "ABEC" rating. That rating system has nothing to do with how fast or durable your bearings are. So we sourced our own high quality bearings, no gimmicks, no fake wording. all bearings break; thats just the nature of the sport, but our bearings are a reliable high quality set that will keep you rolling smooth for a while, with a titanium coated casing and quality plastic separators to reduce friction. Complete set for a scooter, 4 bearings and 2 spacers.
