Snapped seatpost

    The seatpost snapped in half on my aluminum Trek, lucky enough I was on the turbo when it happened.

    Unfortunately one half is still in the frame! Absolutely wedge to it

    I’m going out to the Docman later to have a look at it, but does anyone got any tips to how I can get the remainder of the seatpost out of the frame?

    Use a pair of water pump pliers and some WD40 to twist it out. Or you could drill a hole through it and use a long bolt to twist and pull it out, same as you would by holding the saddle.

    I did it years ago with great patience and a hacksaw blade. I did 2 cuts and then very gently tapped it away with a screw driver. If you have access to taps and die you can thread the interior and put a bolt into it and then use that to remove it.

    Good ideas, but unfortunately there is feck all of it sticking out of the frame to work with! Thanks anyways.

    Thanks Wicklowrider. I presume you didn't cut all the way through the seatpost, just enough to weaken it. It looks like it could be one tedious job!

    I cut until I was through the post at the top edge - because of the the angle I was working at it didn't got through the post further down - its a real drudge of a job.



    Would this be possible with a seatpost, is it not too thin?[/QUOTE]

    I've read online of people doing it.
    Another tip I remember was to use a screwdriver with a right angle at the top. Use it as a hook and tap against the handle with a hammer. You can bend the top of a screw driver in a vice.

    I think that sums it up! Thanks for the tips.

    Is there a narrow slit in the seat tube near the top, to allow the tube to be clamped around the seatpost? If there is, it might be wide enough to get a screwdriver tip in to touch the broken seatpost, and tap upwards with suitable hammer.
