• There are ways to loosen a stuck post. You can try soaking it in oil, you can even take out the bottom bracket and poor oil down the seat tube from the inside. With a steel frame you can also resort to heating the frame with a flame to make the metal expand.

    You might be lucky, you might not. It's a bit or a risk and if it does not work then the rest of the bits of the bike aren't really worth the £50 they are asking for it.
