I have been using Crap bearings exclusively for a few years now, and they hold up very well. They are priced very reasonably, and they last a long time, as long as you avoid skating in sandy or wet conditions. Obviously all bearings will suffer under these conditions. Crap bearings have the longevity and durability that I have grown to trust, and I recommend them to fellow skaters looking for the same quality in the products they choose.
They come in a pack of 8, which is enough to refresh the bearings in the outer wheels of your anti-rocker/freestyle setup, or you can buy two packs of 8 if you skate flat or need to update your anti-rocker wheels as well. Click THIS LINK to check out the product page.
