So I have a stuck post.....Its a Dura Ace Easton post stuck in a Colnago Master frame. Tried WD40 soaking and reading through Sheldon my next stop is Ammonia. I was planning to hang it upside down and pour it through a bottle boss ? Should I really think about stripping the bike down and going in through the BB ? Also will this harm the paint work ? presently I cannot get enough purchase on the post as clamp is now rotating at the top of the post. Next steps ?
1) Drill a hole through the post and get a large screwdriver to give me more leverage ?
2) Cut it out, I can hacksaw down through the slot in the seat clamp
Which will be the best way to protect the frame ?
I suppose my only real question is the Ammonia / Paint one.....
Also in future which is better to protect the post, grease or copper grease ?
