|Seat Post diameter constant?||t-bill|

|I have an American Classic 27.2 seatpost in a Cinelli Supercorsa. Lately I've had a lot of trouble getting the seatpost to stay where it belongs. About a half an hour into every ride it starts to slide down. I though it was just that I coudn't get the binder bolt tight enough (it's a unusual three-piece bolt). But then when I removed the post to try to get a homemade shim in there I noticed that while re-inserting the post it seems to have been harder/easier to slide at certain points. In other words it seemed as though the bottom half of the post had a larger circumference than the top half. Could this be possible? Is it just too worn at the usual binder spot and in need of replacement?

|As stated by Crankist, there may be a problem with the seat tube on the frame. Or maybe the seat post isn't perfectly straight (even if it does have a uniform diameter).|| |
