Tried that, tried drilling the side and putting bolts through and ive weleded it to a metal bar, seat post just got destroyed. Sit post moved slightly but down instead of up
Gonna try cutting the inside of the post and ill try rolling it inside itself
Bit worried that the soda will eat away the alloy threads and mounts etc
Anyway ordered some caustic soda anyways.

I would try some WD40 before going nuclear with caustic soda. Flip the bike upside down and spray a liberal amount in the seattube from the BB or dropper cable routing hole if there is one. leave it for a few hours and then try pulling again.
