off to get the blow torch now mybikes do you know why it says im banned from teambad (phonixmtb)?

I'd get the cranks out and then douse the seatpin in WD from the underneath via the hole at the bottom of the seat tube where it mates to the BB shell, leave it overnight and have another go at shifting it in the morning.

Soak in plusgas. Then get a big hammer and hit the post into frame - then put a old seat onto the post. Then get a lever (I used a barbell) then twist out.

I tried everything when an alu post was stuck in an alu frame.

BTW Tom don't sue me if it damages your frame.

i think ill let mi dad do it then if he brakes it he can buy me another 😉 im going to try the vice and twisting/pulling it out if all else fails ill blowtorch it out

if it's really bad - wd40, clamp frame, drill through the post and put a metal bar through (I used a large drill bit) and twist. Use a rubber mallet to try and release it if you can't do it by hand (hit the bar you've put through, not the frame!)

If all the above fails, we removed a seriously stuck post by sawing the top off,sliding a snug fitting metal block (like a slide hammer for fitting crown races to forks)on the post,and after clamping the post in the vice tightly, drove large screwdrivers between the vice and metal block. It worked, where four of us swinging and pulling failed.

No need for destructive removal, it'll actually slide right out if you use window cleaner (contains ammonia, which dissolves aluminium oxide)
Spray liberally, twist, spray, twist... This has worked for me before. If you used WD40 also, it might make it easier to pull the post out.

Guessing you must have got this out as it would appear that you're selling it on the classifieds with no mention of the stuck post? Or is that a different frame?
