These are better then my other bearings. Because of the both sides are closed with caps, dirt doesn't get in easy. I'm using them 14 months, 1/week (for recreational use and jumping) and they're still spin as fast as day one ! Awesome job thoses Bionics. Still didn't have to clean them since buying them.
