Just wanted to share....
I have an old bike that I haven't ridden in many years (my son is getting his first MTB and I want to ride with him).
So I brought it to the LBS for a tune up after I doused the thing with CLP and rode it home.
But, I noticed the seat was too low.
So I tried to raise it. But the post wouldn't budge. I figured: No big deal, I'll squirt some CLP Break Free and get a wrench and all will be fine.
many hours later, my suspension post chewed up nicely, I was no where closer to loosening it.
So I turned to the web and found great articles about the many ways to attack this problem. I had intuitively done many of them already, but there was plenty of info I did not know.
Most importantly, that the posts are typically aluminum and when aluminum oxidizes inside an iron tube, it creates a super tight bond.
So I got a jug of ammonia and a quirt bottle, turned the bike upside down and took out the 2 screws that would hold a water bottle holder and filled the tube with ammonia.
Did that many times over the course of hours and sure enough, got the thing out.
I ruined it in the process (it had play in a twisting direction from the torque of the wrenching), but I quickly replaced it at the LBS.
I feel all happy about this now.
BTW, I know just about zero about fixing bikes.
Thanks for letting me share (maybe this post will help the next guy who is in this situation).
