Bloody BB refuses to leave me alone; pinging sound has returned after a complete stripdown and running a toothbrush over the frame threads with degreaser. Now my biggest worry is that I may already have cross threaded or stripped part of the BB shell (when I removed the BB there was definitely some thread that had been stripped), since the BB threads themselves seem fine (though I have no idea if it's the cranks being loose on the BB) - is it worth buying a tool to clean/tap my frame BB threads (toothbrush wasn't good enough) or should I just pay the 30 quid for my LBS to do it?
