OK, not sure I have much of a question here but maybe a cautionary tale. Bought a cheap Planet X Ti frame 6 months ago and installed an FSA Mega Exo BB that I had lying around which was used but in fairly good condition. Threads all greased, very careful not to cross thread etc etc.
THe bike has been used but not every day by a long chalk. Today riding home I noticed some play, took the cranks off and the drive side BB cup just fell out of the BB shell along with the cranks. On inspection the threads on the cup are completely stripped. The internal threads inside the BB shell seem to be OK ish - they aren't as bad as the BB cup - so hopefully the frame isn't scrap. I haven't got any spare BBs knocking about so will need to buy a new one and check it can be successfully fitted. fingers crossed.
Must admit I am shocked the BB could be trashed that comprehensively - anyone seen anything like this before or can tell me what I did wrong so it doesn't happen again? Many thanks
