So on moving to the Scottish Borders its become acutely obvious that my stuck seatpost is a liability..., even having to walk down some stuff last night around Innerleithen (the shame :oops:).
So ideas on how to get a SDG I-Beam carbon seatpost out of a 456Ti (Lynskey if it makes any difference) frame, which I think comes with an alloy shim/support inserted (if memory serves me).
The post has been in a couple of years, as I didn't want to break it on discovering it was stuck previously.
And any deals on 27.2 droppers around? 🙂

Good luck!
I had to cut my last one one out. Should be too hard to cut carbon while not damaging the Ti.
wear a mask if cutting carbon and either cut it wet or hoover the dust up.
Why did you have to walk down? Just MTFU and ride down with the seat at its normal height! It's not obligatory to drop the saddle!
My Easton carbon post does get stuck in my Global Ti frame. It's a tight fit anyway and when mud gets in it becomes even tighter. The only way is to rotate it while pulling upwards and accept that the lacquer is going to get worn away.
Then give it a good cleaning and clean out the seat tube with a corner of a rag pushed down with a long stick.
Best bet is clamp the seatpost in a vice (i.e. with the frame upside-down) and rotate the frame around the seatpost - you can get far more torque on it this way - worked a charm for me a few years back when in the same pickle - good luck

Hmm, this picture should give you an idea - and although my legs are long enough to can get behind the seat, its a recipe for disaster on a steep offcamber down through trees, at dusk.

The post was 'welded' to the shim, now spent the best part of four hours trying to get the bit off the post that fell in (to the gap between the shim and BB) - not one of my better days.
