I have the blade grips with the 2 ball bearings and a brass tube and I assumed I had the 2 bb grips but when I went to the lhs to get the 3bb grips I looked and the package said 3 bb but had the same setup as mine 2bb and brass tube then the other option was a pack of blade grips just had brass bushings.Am I crazy or where is the third bb or did the store mark the package wrong? Do I have the 2 or the 3 bb grips (I would assume only 2)? Also where can I see a pic of the 2 or the 3 bb grips so that I can identify what I have?
