Aaaaaarghhh!!!!

So that old recurring problem: creaks and squeaks in the bottom bracket area.

Probably looking for sympathy as much as advice:

Once my bike warms up (or I do), I have a click or double click on every crank revolution. It stops when I stop pedaling and occurs at the same pedal position on every revolution. Hence I have concluded it is pedal/bottom bracket/chainset problem rather than wheels or drive train.

Took pedals off – greased everything put them back on. Noise recurred (it also occurs when I unclip and pedal with just one leg on either side).

Took cranks off, removed BB, greased everything put it back together: Noise.

Repeated above, fitting a new Dura Ace bottom bracket: Just the same noise.

Nothing catches (e.g Front mech wire), chainset bolts are tight.

It is so annoying!!! Any other suggestions (pretty sure it is not my knees)??!! I think I may go mad.
