what did you try on the seatpost? some guys here seem to have luck with removing the BB and pouring amoena down the seattube and letting it stand for awhile.
First I tried penetrating oil over a several day period, and I tried household ammonia again for few days. After destroying 2 saddles I managed to get it to turn about 45 degrees left and right, but I could not get it to move vertically. At this point the seat rail clamp on top of the seat post started turning. Since it fits me with the saddle thats attached I gave up.
Looking at Sheldon Brown's article again I did not try the dry ice approach. so I will do that this weekend. Unfortunately I am limited in the torque I can apply with the seat clamp twisting on the post. I'll have to drill a hole in the post and put a bolt through it to apply more torque at which point I would be fully committed to removal and replacement, since it would probably no longer be safe to ride.
