errmmm okay I am a novice I do admit. But I really am not understanding why I need bearings at all?An ultimate wheel has stationary pedals attached to it...I hope that clears up another sloppy communication on my part. Welding it in place is no issue I was just hoping to make the axle removable as well but I'm guessing not. I'm considering placing the axle then using jb weld to lock it in place and and then tighten down the race cups and weld them on.. then use the axle for pedal arm mounting,
