Hello,
Has anyone else had problems with (re-) installing steel seat posts?
Over the past year or so, I've only dealt with a few steel posts,
but had the following problems:
1) I undid, removed and regreased a steel post, then reinstalled it
but found I could not get the post clamped securely in the frame,
there was always a bit of movement. I am pretty sure it was the right
sized post for the frame - it was secure when I bought the bike, but after
removal I couldn't get it tightened up enough. I eventually gave up and
used an aluminium post.
2) More recently, someone asked me to do up a bike for him. I noticed
the new steel post he had used was loose, but again I could not get it tight enough. I measured the post and frame, and both seemed to match, but
even with the clamp done up very tight the post slipped when I put any significant weight on it. In this case, I replaced the original post with another
old steel one I had in my bits box, which I was able to get tight enough to ride.
Any idea why these very frustrating problems occur with steel posts? I know there are inaccuracies with the measurement of frames and posts by manufacturers, but that doesn't explain the first case, where the post seemed to fit at first, then didn't later on... Is it something to do with the
use of chrome on the posts? Or the flexible nature of steel compared to aluminium?
Sorry for the long rant, this has been quite annoying...
