I have skimmed the previous creaky threads in here, so this is more of a vent than anything else. I of course welcome advice on anything I may have missed.
Rode home in a bit of a rainstorm last week. This, after I had spent the previous weekend cleaning my BB shell and cups, lightly greasing the shell and threading the cups with teflon tape. Removed and cleaned the RD, hanger, and seatpost as well. All that's left are pedals and then possibly *gulp* the frame. Since the symptoms cropped up after the rain, but having just rebuilt the BB, I am thinking it's not the BB. I even removed and re-installed the FD just to be sure.
Guess it could be the chainrings, but hoping for the best. Only happens under load, but it doesn't take much to get to Creaksville.
