If you aren't averse to chemical burns, lye might be fun.

Priceless advice, thank you. I am going to try each recommendation,
methodically. The seatpost is a Kalloy Uno, and the frame is
(probably) Reynolds steel tubing, so I think that is a chrome finish
on steel. If that's so, ammonia will is probably contraindicated, but
I will try that, too, if all
I had the same problem with an aluminum post stuck in a steel Bianchi
Volpe frame. I tried all matter of twisting, tapping, penetrating,
etc. I finally pulled the bottom bracket and turned the bike upside
down. Ran about 2 or 3 cups of ammonia down the seat tube and let it
sit overnight, did th
Another vote for soaking with liquid penetrant. You should consider
removing the water bottle screws from the seat tube and using them as
a way to add penetrant from the bottom of the bike. If your Trek does
not have water bottle mounts on the seat tube, you could remove the
bottom bracket and a
Thanks very much for the suggestions. I particularly like the advice
to wait a while & let the penetrant do its thing, because that is what
I'm doing now. I have the bike in my living room to remind myself to
drip a little more liquid wrench in every day, and to give the
seatpost a daily nudge o
I'm with Bill C. Let it soak in a few applications of penetrating oil

It won't help now, but one thing you DON"T want to do is mix greases,
like using both Phil and anti-seize. Grease is basically oil plus a
thickener, and many of the different thickeners used are chemically
incompatible with each other. They may react and either lose their
thickening power and ge
I have occasionally experienced this too. Eventually it will release.
The ultimate fix is to cut the top of the post off just above the end
of the seat tube, then use a hacksaw blade down inside the post to cut
a slot. This always works. Just be careful you don't cut into the
seat tube: gentle
