It's not the front hub - this was dismantled and greased a couple of weeks back.
It might be the seatpost (again) but it doesn't sound the same as it did last time.
I don't think it's the BB (changed the bearings last week as it was a 'bit stiff' ie. the NDS bearing had seized and it's now spinning freely).
Any other suggestions? Could it be that I've not seated the BB bearings properly (BB30 and pressed home with a headset press until they stopped)?

saddle, seat clamp, seatpost, pedals?
can you narrow it down?
standing, not pedalling
standing pedalling,
seated not pedalling
seated pedalling
and see if it comes and goes?
I'd check where the gear cables go into the frame etc - mine squeaked for a while until I put a dob of grease on them.
saddle, seat clamp, seatpost, pedals?
I shall try lubricating all of the above.
Seems to happen at slowish speeds (ie climbing) and I'm not sure there's much difference between standing & sitting. I [i]think[/i] it happens more when I'm pedalling. It's not the fork cycling.
Can a BB (esp. a press-fitted one like BB30) spin smoothly but creak under load? If it is that, are there any solutions (apart from Loctite - but if I do that, will I ever get the bearings out again)?

Drag your brakes a little to see if it is the pads on the rotor.
After installing new pads I'm getting a small squeak.
How likely is it that the bearings the freehub spins on could be seizing?
Definitely not BB; squeak only there when pedalling (so freehub turning on its axle) and not there when freewheeling. Not pedals, though I concede they're a bit stiff and need attention.
