Find the creak

[shouldbworking]

Ribble winter audax. Creaking each pedal stroke, particularly noticeable when putting the power down. Can't reproduce it in a workstand.
Have tried - cleaning and regreasing entire drive train and (spd)pedals
Checking for play in BB / crank arms
Checked chainring bolts

The chains never been apart before and as its seen a few thousand miles use im somewhat cautious about how it might behave with a powerlink in. At the moment its not slipping or anything.

I guess I should just get on with it and break the chain / remove cranks to see how the BB feels, but I just wanted to see if there were any other ideas before I tear into it?

Cheers all, good ideas for me to chase down. I haven't tried seatpost / headset or saddle rails yet. It still happens when out of the saddle, sounds like its coming from the BB area but experience has taught me that where it sounds like its coming from when riding can be a deceptive.

Had a proper look at it finally this weekend. Combination of two things - one very very very slightly out of true chainring, and a front mech that had apparently managed to work loose and slip down to the point where it would just contact the teeth of the aforementioned chainring. Moved it back up to about 3mm clearance and all is well.

Not sure what I'll do about the chainring though. It's not causing any dramas riding it... it'll go on the back burner along with the new wheels required. Drivetrain might find itself on here in pictures soon as I'm a little unsure about the level of wear on it.
