We had a mystery noise that would come & go only when pedaling and on the bike, never on a stand. It turned out being a loose BB, not the BB itself, but the retention cup/nut/thing. It really sounded like it was the stoker BB and all of our investigation was focused there, but it was actually the captain's BB.
