Stuck Seat Post

[DebW]

I've heard of clamping the post in a vise and trying to twist the frame (you'd need a new seatpost after that). They can get really stuck and sometimes there's nothing you can do. That's why you always grease a seatpost.

Here's the farm fix - wipe off any oil or grease (anything flamable) then hold a lighter to it, not enough to set anything on fire but just enough to make the metal expand a bit. Then give it a sharp whack with a mallet, not up or down but just to make it twist. Once it's moved even just a little it will be easier for the oil to get in between the parts and you'll be able to wiggle it to where you need.

Clever, Kat!

Sheldon Brown has an extensive article on stuck seatposts (of course):

As a music teacher you get a lot of students who get their mouth pieces stuck in their brass instruments, normally we have this nifty tool but with tubas it doesn't work so we would put the tube (your bike frame) against a softish hard surface (mdf or something like that) and tap tap tap with a rawhide mallet, always worked. it'd give it a go.

yeah, Karen, did you fix it?

No success yet -- but it's not a real high priority project, since it's unlikely he'll ride that bike again. On the other hand, maybe if this can be solved, he will want to ride it, but otherwise, some new owner will be happier with it if the seat is adjustable, so I'd like to solve it eventually!

That is indeed the worst problem a bike can have, and its the thing LBS guys dread the most. I just read an article on this in Bicycling magazine...here's the link:

Good luck!!!
