I've also preserved the paint on all the bikes, including one touring bike with all sorts of stickers from the lands it graced.

novel way to remove a stuck post

Maybe that is how 'the seatpost man' does it?

any tips for carbon seatpost stuck in carbon frame? will more than likely send to the seatpost man but thought i'd at least try something first...

I have lived with a stuck post for over 12 years. There's a lovely Salsa seatclamp around it that I'd like to repurpose though so hot & cold method will be tried which might yield a saved seatpost too I guess. Keen to avoid destroying frame.

Get some ice and be diligent about the hot and cold then penetrating fluid for a couple or more times a day.

I've most success the longer it is left.

Time and patience is key.

Just thought i'd report back and say yet another endorsement for the seatpost man. Posted my frame to him yesterday, he received it today and I had an email from him this evening letting me know it had been removed - great service!

Are you doing ice cubes then kettle alternately?

Yup, if I feel generous.

Gonna attempt a triple extraction in a day next week, signing off in style!

Stumbled across this thread… my brother purchased a 753 frame (unusual ‘Spen Velo’) some time ago with an alloy seatpost stuck.. managed to remove the old one using a horizontal boring machine at work.

An extreme way to go by machining the bore of the post until it went to wafer thin alloy, but did the trick 👍

Seatpost No. 30 removed!

Bloody thing had only about an 1 1/2" sticking out!

Must have been all the way down to the bottom bracket.

Don't usually have to loosen the bottle cage bolts to get the seatpost out!

Didn't even noticed that.

That wasn't me, someone else called me in after they've failed.

Is this with the ice and boiling water technique you’ve mentioned previously?

Yup!

Do it enough and it'll eventually comes out.

Finally got round to getting this one out, in the end copious amounts of plus gas about two hours of my day and loads of leverage in my my vice broke it free.

I don't think it had probably moved since my other half bought the bike from Tokyo Fixed about 12 years ago, it was locked on Waterloo Bridge all day for a number of years, proof that the ball bearing trick stops the seatpost/saddle being nicked but that it's a good idea to remove it and move it now and again (and that maybe it was corrosion not the ball bearing eventually)!

Finally got a seatpost twisting in the hole, that's been in there for over 10 years. So, it looks like it's going to come out eventually.

What should I do post-removal to tidy the inside of the seat tube, and stop it from happening again?

I’m trying to remove a carbon post from an aluminium frame, I really want to save both the frame and the post. So any top tips? If it comes to it I’ll cut the frame up to save the post, it’s only an old SWorks after all.

Isn't it that it formed a bond due to lack of grease on the post and if you grease the new post (and check it now and again) you should be fine?

What material is the frame?
