My Masi track frame (04 34) measured 27.2, my seatpost measured 27.13.
Possibilities:
Assuming correct measurements:
Seat lug squeezed down from use of undersized seat post.
Upside down seat tube. Seat tubes are single butted, 1.0x.07, thick on the bottom and thin at the top.
Was there ever (to your knowledge) a correctly sized seat post in the frame?
Good luck,
Jim
