Heres the dealio, I can't get my cranks spaced right so that they wont shift back and forth. By shifting back and forth, I mean the arms, Spindle and bearings altogether. I'm not sure if it is the tube spacer in the middle that is not the right size, cause the cranks only came with one, but I tried using an arm spacer along with the tube spacer between the cups and bearings, and it solved nothing. I need to get these running soon otherwise it'll drive me nuts and I wont be able to ride without going nuts thinking something will get fcuked up.
