I have a problem that's been discussed plenty of times, but none of the methods have worked. I have a carbon fuji team frame that is stuck with an aluminum post. I brought my bike to a bike shop and they tried putting the post on a vice grip and twisting the frame, and that hasn't done anything at all, other than gouge up the seatpost. Lately i've been shooting pb-blaster down the edges of the seattube, but that has not worked.
I'd definitely try to shoot the pb-blaster or coke up the seattube via the bb shell and let it sit, but that would require me be off the bike for a few days/weeks, and that's not quite an option for a long time seeing as it is road season now. Most of what sheldonbrown's site isn't very much help, and most of the success stories i've read came from non-carbon frames. Any ideas?
