Got a new saddle for xmas. I need to readjust the seat post's height. Went to take off the seat post and couldn't. It was hard to budge. I could move it back and forth about 2 inches and could pull it up about 1/2 inch, with a lot of elbow grease. I know it wasn't sticking metal-to-metal, 'cuz I can move it back and forth.
I gave up and took to the LBS to see with they can do. I was lucky that there was a guy there that was twice my size. After huffing and puffing for 15 minutes, he was able to pull the seat post off. Man, I was tired and sweating from the ordeal.
Anyway, installed the new saddle that I got from xmas and went to insert the seat post and could barely get it into the seat tube. I was able to force it in about 1cm. My wife's bike had the same seat post (27.2), so I try inserting mine into her bike and it went in fine. So, my seat post is fine, it's my seat tube that has shrunk.
I'm wondering what happened to my seat tube. Did it shrink? Did I tightened it too much in the past that now it won't open up? I placed an order for a 27.0 seat post. I thinking this should be fine, eventhough my seat tube takes a 27.2. But what can I do, the seat tube has gotten smaller. Is it ok to use 27.0 seat post on a 27.2 seat tube? Or is there a way to get the seat tube back to be able to take a 27.2 seat post?
