    Post on this problem recently.

    You will probably have to buy a new seatpost after you destroy old one getting it out.

    Might be worth talking to Mr. Skeffington as he can probably get the old one out and supply you with a replacement.

    THe only way left now is to cut it out with a new hacksaw blade (along the inside of the post) if it's alloy you will cut it out in 15 min, if its mild steel it will take longer. Tedious job but always works.
    Good luck with it.

    Hi new to this forum and this is my first post.
    If the frame is metal you could try to gently heat it where the seat post is and while it is hot try to remove the seat post. You could use hot water to heat it.

    If you are that desperate, and almost ready to write off the frame. I would consider heat and as a last resort, crushing the post.

    First, spray wd40 on the outside, and inside - cut the post if you have not already done so. I would do this every day for a week. Use at least a full can. Your bottom bracket will probably not be too happy with this technique so get ready to take it out and re-grease.

    Next, drill a hole through the seatpost at the top so that you can put a bar or screwdriver through in order to try and break it free.

    Then, I would heat it up. Don't glow it, yet, but have patience. Heat, try to twist, cool, WD40, and so on.

    If the frame isn't worth much, or if you do not have a lot of patience, get it nice and hot, and try twisting.

    In the end, you may wish to try and crush the bar into itself, more complicated than it sounds as you do not wish to take the circular cross section and make it oval. The frame will not appreciate this.

    If you can see where the rust is prominent, try crushing so that you lose contact there.

    But, if it is between the trash or crushing...
