I recently built up my first aluminum frame, and I was feeling what I thought was flex in the BB. I could look down and see it moving, everyone just told me it was just frame flex. I took it all apart and regreased and retorqued everything just for my own sanity, now a couple days later I was looking closely and I can see the cups moving in the shell, I'm scared to take it apart, but I am assuming I have stripped my BB shell. My questions are A: how the hell did this happen? and B: is there any solution to this or is my frame now trash?
