Method for finding a creak

Okay, the creak wasn't in the bottom bracket, the crank or the pedal
fixings, which have all been disassembled, greased and retorqued. THE
CREAK IS STILL THERE.

If I stand up on the pedals, the creak goes away.

What I need is a suggestion of where to look next.

Thanks.

"stand up on the pedals, the creak goes away."

Saddle, post, clamp etc?

My Brooks creaked for a while, leather rubbing agains a rail. Sounded
just like a loose crank creak. Drove me battier. Touch of sno seal
at all the leather steel interfaces cured it.

Mind your own beeswax, eh?

There's your method - you've just eliminated the seat.

The seat.

I had something similar and it turned out to be coming from my front
dropouts. Put a bit of grease and tightened the easy off more and it
went away. Subsequent tests showed that the grease was not necessary.

That was my reason for posting here and it worked out.

Yeah but depending on the bike, standing may shift weight OFF the front
wheel.

Seriously - if all else fails - find a quiet road and a friend. If the
creak appears at low speeds then cycle slowly while the friend jogs
along beside you listening carefully until they can locate where the
creak is coming from. If it only occurs at higher speed then your friend
cycles beside you and attempts the same - harder to locate accurately
though.

This really works as human ears are really only designed to locate
sopunds in a horizontal plane (assuming a relatively upright body). Your
friend can reposition themselves to locate the sound whereas your ears
(unless you have a very unusual body construction) are symmetrically
placed over the bike which makes it almost impossible to localise in the
up/down, forwards/backwards directions.

Once you know precisely where the noise is coming from - saddle, frame,
headset, cranks, rear bearings etc... - you shoulkd find it much simpler
to work out what is causing it.

I had similar. It turned out to be the clip mechanism on the SPD pedals.
When I changed the position of my foot e.g. standing up, it went away.

I poured some oil over the clip springs and this fixed it.
