stuck seat post

October 17, 2008 (about 1 year ago)

I have a really good question: How do I get a stuck seat post out of an old Fuji bike? I got this frame for free because the post is stuck in there really tight. When I received it, the post had marks from a pipe wrench.

I tried hooking up a seat then pulling by the seat.
I tried using a couple different wrenches.
I tried cutting down the side of the post and pulling with vice grips.
I tried drilling a hole through the side and putting a bolt through the hole. I then tied a strap to the bolt and pulled on it with the car! I was scared it would pull the frame apart and screw up the car so I gave up on that.

I am assuming that it is permanently stuck.
Ideas?

Looks like Steven read Zinn and the Art of Bike Maintenance. There is a fairly elaborate description in there.

what material is the frame what material is the post? you could consider using heat... but you need to be careful!... Other wise, Grip the seat pin in a Bench vice and use the frame as leverage.... again be very careful, I've seen a seat posts twist and snap using this method....

I've heard of people using a hack-saw blade to squeeze in and physically break up corrosion.

yes, that and liquid wrench. The longer it marinates, the better. However, find out if the previous owner used a bonding agent to permanently seize the post in place. In that case, you might have a fixed post...

Kroil. Pour it down the seatpost, and if possible, take out the BB, flip the bike, and pour it up the seat tube. Let it sit for a week. Then, with the bike upside down, put the seatpost in a vice, and use the bike as leverage to break the corrosion. I have done this on numerous occasions with success.
