• Post is kalloy, almost went for a nitto but i'm glad I didn't now because I gouged the crap out of this one just trying to fit it. Cutting it down is an option.

    Any ideas why it would jam after a few inches? The top of the tube doesn't seem flared, infact the whole frame is in really good shape except for the paint. I might just attack the seat tube with a small wire brush on a drill and some wd40.

    Theres also some artefacts rattling around in the tubes, flux or a bit of rust maybe. Any solutions?

  • Take it to your LBS and have them ream the seat tube to match the specs. There could be anything down there - leftover brass or other schmutz, or possibly even a slight bend that constricts the tube enough to stop the post.
