very gutting but... please learn from this and do it properly next time! so many threads on this kind of problem! 1. left cup in, half way. 2. right side with bb axle in all the way, tighten. 3. left cup in all the way, tighten. and note : if you feel any resistance at all, stop tightening! just wind it back out. the cup should feel silky smooth going in if you've done it right (providing theres no threadlock on the threads ovcourse )
