I've got a Trek 930 (DB steel) with a cheap Kalloy seatpost wedged in it real good. I've tried everything from brute force and ignorance to squirting half a can of Liquid Wrench through bottle cage mounts and leaving overnight, also heating/cooling cycles and even slicing off top of post and cutting slot down inside with a hacksaw blade, still the m/f will not move! I have gotten to the point where a deeply personal vendetta exists between me and the seatpost, I will not quit! If anyone has any magic cures for this problem I would greatly appreciate hearing about it. (I have visited Sheldon Brown's "15 ways to remove a stuck seatpost by the way so I don't need telling about that again)
Ride on.
