Saddle Problem

    Hi

    I have a mountain bike with some wear and tear. It's a good bike. My friend left it out in the rain and it rusted up a bit. I got it all repaired but I cannot raise the saddle. It is jammed pretty tight. I've tried throwing on some wd-40. Still won't budge. Brought it to Quay Cycles in Drogheda and the guy said that I won't be able to move it because it's "set". Does anybody have any suggestions as to how it might be possible to budge this seat. I've tried using a car jack but the force just wasn't going in the right direction and I was bending the saddle. Has anybody any ingenious ideas for sorting this out. It's unlikely to move but I want to try!

    You may have to sacrifice the seatpost. You should be able to re-use the saddle. Seatposts are not very expensive.

    Who repaired it and what were the nature of the repairs? If the repair was recent and involved the seat post which has subsequently stuck maybe the person who did the repair will stand over it?

    If you are going to get the seat post out yourself you should start with taking off the saddle befoe it gets further butchered. Then read the tips which blorg linked to.

    1. Remove saddle
    2. unscrew seat post clamp
    3 secure seatpost into a bench vise
    4. Use bike frame as lever and twist the frame off the seatpost.
    5. Buy new seatpost
    6. grease newseat post BEFORE putting it back into the frame to prevent same happening again.

    I think the danger of putting pressure on the frame is that you could bend it.

    If the seatpost is THAT tight, then so be it...clamping the frame and trying to twist the seatpost is harder and much more likely to damage the frame.

    If you can bend the frame by clamping the seatpost in the vice and twisting, then the frame is not strong enough to be safe to ride. Hence there is no loss breaking the frame in such a way but only the win of preventing a potential serious injury.

    Seriously the frame is put under more pressure riding down the road than you can produce in the above scenario

    Maybe your right. But you can put massive pressure with a lever the size of a bike in a vice. I've seen vices break with people putting pressure like that on a vice. As thieves can bend a frame around a lampost I imagine they are not that hard to bend. Maybe I'm wrong I've never done it.
