Whats the best way?
I've got a mid school gt pro xl alloy frame and a gt alloy micro adjust stuck in it!
I've had it in the vice but the post just bends.
Any ideas?

How deep is the post inserted down the tube?  When an alloy post/frame corrodes, it's almost as if it's welded together.   >:(

After trying all methods available to me, I chopped the top off the post and cut the rest of it out using a hacksaw blade whilst wearing a suede builders glove.

It took a while mind so only consider doing this as a last option.

Drilling would work if you get access to a pillar drill or similar.

MartyC:
belt the top of the seat post with a very large hammer to break the seal that has formed, if that fails then fill the seat tube with diesel and leave for a day or so before trying again.

GavinDavis:
Tighten and old stem around it and use a tube for a bit of leverage on the quill.....worked for me :)

Doing this ^^^^^ on an ali post with an ali frame  :-\ :-\ :-\  :shocked:

Like Ozone said, a pillar drill. I'm sure you have a metal workers place near where you live. Go through the drills in sizes using each one as a pilot drill but make sure it's straight with the frame. Slowly does it is the best way.
