They are 10 under bearings and 10 under grind... but does my above question seem alarming to you? Have you done 216 bearings before? It just seemed odd to me that they come up passed the deck etc... half of a circle isn't going to come past half of a circle, lol. I've never don a shimmed type bearing before though. Thanks for the comment and good question, any one else any input? -freezerburn
