Broken off seat post

Yo,

My seat post broke off in my frame and I've tried all sorts of things with no luck.

Any ideas as to how I can get it out. I seems to be corroded in there.

Its a cro mo frame redline monocog frame with an alloy seat post stuck in there.

Thanks in advance for all replies.

Do they come in waves?

A bunch of new folk come on and they are all about posting silly questions without doing some research first, then they all catch on and the next wave of new kids DO utfs, but they don't notice when things have been posted.

Can we study this so that we can predict the patterns?
How about a warning message before anyone in the nursery is allowed to post?

"Wait! Make sure you really want to send this comment. Do you think this is something that someone else might have already asked multiple times? If so, don't post about it again or you will have an angry deaf bob jackson enthusiast grumbling at you.
Have you checked the date on the thread your posting to? If your inquiring about something that was offered for sale more than six months ago, you might want to wait and send a PM (when you are out of the nursery) addressing the fact that you doubt the seller has it anymore, but you thought it was worth a go anyways. Do this or you will have a cranky American woman taking the piss out of you.
If you are certain that the post you are about to submit will not cause people to create tags about you or ridicule you unduly, then post away!"

IS there any post protruding out of the top of the seat tube?? If not you could try fitting a crowbar down and hooking under the bottom edge of the post.

You might have to spend some time with a hacksaw blade cutting the post into sections if there isn't enough showing to get a grip on. This can be a long drawn out process but it does work with some patience.

Very good tip that was given to me when my seat post get stuck (well cut, from some light fingered t**t) insert a quill stem if you can, tighten up (make sure you have handlebars attached still) and twist to feck :) worked for me and i had 5mm of tupe left sticking out of mine.

Cool, thanks for the replies. The guy at Armourtec says that when they bake the frames to 800degrees to burn off all the old paint, it will probably melt the broken post enough for it to fall out. the paint getting a bit tired now any way so I might do that. but I'll try all your suggestions first before spend £50.

Cheers.

If it's an alloy post in a steel frame then you can also try plugging all the holes in the frame and filling the seat tube with bicarbonate of soda, this eats away at the alloy but the steel is unaffected.

Brilliant tip - thanks. I have a remnant steel post deep inside steel (vintage 1950's) frame.

The easiest way to remove stuck seat posts from experience is to hacksaw or use an alligator saw, you can rent this at most hire and buys, Make sure that the blade is long enough to cut through the whole length of the existing stuck piece of tube.
