Given that the builder could ream it to any size they wanted, the idea that tube set X is seatpost diameter Y is at best a little floored.
Your premise is a little floored. Both my Reynolds tubesets have seatpost diameters smaller than I had somehow ended up believing they would be. Unless your builder is able to ream material back into the tube, rather than take it away.
