Laing, your point is exactly my point. If you use the same lugs you do not change the OD otherwise the lugs would not work. If you want to use the same lugs and want a thicker tube, then it must get thicker on the inside, so the inner diameter must decrease with a thicker tube. That's my understanding of why the seat post is now smaller in diameter.
