HELP: Dx this!

So I get on my second bike the other day and do some hills. Creak,
creak, damn. Hate that.

The following were performed in attempts to isolate the problem:

- swap wheels
- swap pedals
- remove, clean, lube, replace chainring bolts
- pull crank and bb, clean threads, lube,re-install and torque to
specs
- remove stem/spacers, lube spacers, lube stem bolts re-install
- lube chain

None of these things made it go away. Also, standing on the cranks
and locking the brakes while applying as much pressure as possible
WILL cause the creak both during pressure and when released or when
switching to the other pedal.

I'm thinking BB, despite my efforts. Chase the threads, use teflon
tape? I am almost to the point of going to the not-so-local BS (about
a 45 minute drive) cuz I don't seem to be able to fix this one.

Help!!!

Hollow tubes transmit sound quite nicely. So tracking down the source
of the noise can be tricky. I would check the handle bars/stem. I would
also examine the cranks carfully to see if they are cracked. Same thing
with the BB, check for a BB that is about to break.

Could be the interface between the crank arms and BB. Could be something
with the fork and/or headset, like the race on the fork crown or the cups
that are pressed into the frame. Since you're sweating this problem, might
as well make sure that your seat post is greased just to rule-out one more
possibility.
