Caustic soda
My brother had used this as have many others on here. Nasty stuff but be careful and you will be fine

Probably worth asking in the pre '97 retro chat section and you will get plenty of friendly help from more helpful people than me! :roll:
 
Re:

Not Caustic soda, because this is an aluminium frame.
Caustic soda is sometimes used to dissolve aluminium seatposts, in steel frames only.
It would seriously would damage an aluminium frame.

It looks like someone as had a go at getting it out already, and not much seatpost is left sticking out, to grip onto, and work with.

Probably the best method left for you is to try and cut it out with an hacksaw.

From Sheldon Brown website:
"Cut the seatpost off so that about 1/2" is left sticking out, then insert a hacksaw blade into the seatpost and carefully cut a slit (vertically down) in the post. This is very laborious, and you run the risk of damaging the frame if you cut too far, but this approach cannot fail. Once you have cut the slit, grab one edge of the cut with a locking plier and roll the seatpost up inside itself and pull it out."
You can find examples of people who have done this on the web:

Or maybe you could take it to a local bike shop, see if they can do it.

Note to self: read the thread properly / click on the links :oops: :facepalm:
Quite right, caustic soda only works when aluminium post is stuck in a steel frame so this is no hope to you at all.

As Ceefax says, Sheldon Brown is a great site/technical assistance for things such as this so well worth a look.
