Can rotate seat post, but it won't extract or insert in the seat tube.
Hello. Hope someone can help me with a situation I've got with a cycle. I have two cycles where on one I've managed to raise the seat post with some difficulty and on the other cycle the seat is stuck down, yet on both cycles I can very easily turn the seat-post round. (Obviously with the QR clamp released.) Does anyone have any good tips on how to release the stuck seat-post so I can raise it out of the other cycle? These are new cycles.
It looks like on the seat-tube I managed to raise that there is burring (if I've used the right word) along the length of the seat-tube.
I can't post any pictures at the moment as this is my first post.

What are the materials of the frames and seat posts? Use a magnet to determine if anything is steel. Have you used penetrating oil yet?
One method involves a bench vise and a helper, with the wheels removed and the seat post in the vise.

I think if the bikes are new, you should take it back to the shop and let them handle it since even though this is a pretty simple problem if anything were to get damaged while you were trying to remove the posts, they could claim it was your fault and leave you with the cost of repair/replacement.

Yes. They are new. That is what is going to happen. I just don't understand how its happened. Didn't think about using a magnet to see of it's steel aluminium or some sort of alloy.

I'm going to ask a daft question. Are there seat posts that have circular burring along the length of the seat-post as opposes to smooth seat-posts? (It would be easier to show the issue, but I can't put up a picture until I've written 10 posts minimum.)

By rights it should be a trained member of staff that would be adjusting the bike, but I can see someone trying to adjust a bike that should not when I'm not looking.

I learned a lot more when working for a LBS.
I get my knowledge from whereever I can.
I would be a fool to refuse hands-on knowledge that could be easily obtained locally.

I'm not seeing the issue. The circumferential texture is from machining during manufacture.
Your post & seat tube should be greased though. Any generic plain bearing grease ought to work well enough to prevent binding. Your bike shop should have applied it during assembly.
(I'll reserve judgement whether or not your bike shop is reputable for another time.)
Seeing that they couldn't bother to take the time to properly grease the seat post, you may want to take it upon yourself inspect & grease all the other thread interfaces on the bike to prevent a lot of future heartache.

Now there is a good question. I will check this today. Won't be able to check this on the second cycle where the seat post is stuck down, but will try again to free it Bike shop is a reputable one. The leisure trust I work for had purchased numerous things from that and there have not been any problems.

2) I’ve got some split wooden blocks with seatpost-sized holes in them which allows me to clamp simple seat posts w/o ovalizing them.
3) to ovalize a seat post to the point of making it (more) stuck or damaging the seat tube, you’d basically have to grasp it right outside the seat tube. If you clamp it 4” away, it’s not a problem.

Problem was solved at a cycle workshop, but there where four cycle mechanics hanging off the cycle. I'm guessing two holding on and the other two pulling at the seat.
Seems the bottom of the seat-post got stuck on a weld within the down-tube. Seat post was shortened. I had no chance of doing this myself.
Case now closed. :-)
