is the frame in question Steel or Aluminum?
i just reset a Tange Champion steel frame and that sucker is tough to move..
If your frame is steel. you may have bent OTHER tubes and twisted the frame as you reset it.
that twist may have left the seat tube "centered" in the middle, but out of true at the top and bottom......... a definite possibility.
