Greetings fellow bike nuts.
I have an old Diamondback Sorrento frame that I want to build up into a short haul (1.5 mile with some hills) bullet proof commute beast for a friend. It's nothing fancy by a long shot but it is a very sturdy CroMo frame that is just what my friend, we shall call him "Tubby" needs.
Problem is that it came with a dumb shock absorbing POS seat post that is stuck, and I mean STUCK in the frame and needs to be removed because the funkey hardware on the top end is trashed. I suspect part of the problem is that to accommodate it's internal spring this pig is at least a foot deep into the frame.
I have pulled a lot of stuck seat posts but never had this much trouble. Have tried all the usual tricks like soaking it in ATF from both ends, installing an old steel seat clamp and beating the slobbering wizz out of it, heat gun on the seat tube and ice cubes down the post. No joy.
Only trick I have left is to drill a hole in the BB and use a long steel rod to try punching it out from the bottom but I would like to avoid drilling holes in the frame.
Any bright ideas other than toss it in the recycle bin at the dump?
