I got an aluminium seatpost stuck fast in my carbon XLS frame. After a bad day at work I went at it using a hacksaw cutting it within an inch of the frame, my intention was to try the method where you cut a slot in it using a hacksaw blade. I had to resort to this as clamping the seatpost in a vice and turning the frame was making no impression on it at all.

Problem is that cutting a vertical slot in it seems almost impossible with a single hacksaw blade. Has anyone invented a tool that can help? Or can anyone offer some other advice, at the moment I’m in despair and googling for disk compatible CX frames

Are you trying to cut a slot down the length of the seat post internally?

Keyhole saw for that job. Don’t see how it would free it up though.

Yes inside the post. Sheldon Brown told me to do it.

I my also have just accidentally ordered a Crox de Fer

Try theseatpostman

He’ll get it out

Drywall saw

Saw a number of slots then spiral it in on itself with molegrips.

+1 for the seatpost man. He’s on Facebook as well if needed

When leverage has failed and before going down the cut/grind route, badly seized things usually come out when one part is heated or cooled! I wonder if a plumbing freeze kit could work, or a sensible application of the opposite, never attempted it on a bike seatpost TBH!
