I would go with WD-40
Anything other than that!
Well, Im out of ideas really, WD-40 is my go-to for just about anything (that I don't intend to eat).
Maybe you can add what the material of the frame and the seatpost are to the best of your knowledge?
I'm sure there will be an irrelevant music clip or some useful advice shortly
Might sound weird, but can you figure out how to soak it in vinegar overnight (cheapo homebrand white vinegar)? I forgot about this old diving trick and used it on a completely stuck/corroded window latch this weekend. Unfortunately I can't figure out how to actually do it to a stuck seatpost.
I know another bloke who has 50 ways ...
...as predicted by PT.
Well I posted the irrelevant clip. Where's your useful advice?
Well, I had this problem many years ago with a steel post stuck in a steel frame. I resorted to sticking the post in a vise and twisting and pulling and wrenching and destroying the seatpost and still didn't get it out.
So, I am not sure how useful that is (though it is certainly more useful than an irrelevant music clip) but, depending on how much you value the frame, it might be worth a try...
Ah if if only it was a thread about a stuck wheel skewer - fifty ways to ease your lever:
SBS You're an absolute classic, tell me did you ever do training in song writing?
I think you really have a hit there! Lols.
(I'm sure most of us were sitting there watchin Mikes posted Youtube clip listening to PS and the dulcit drummings technics of Steve Gadd, and reading your lyrics, come on you know you were :+P)
Apologies for going off topic....my only suggestion LBS it before it too late!
