bad luck- High performance bicycles are made of thinner tubing, so the hole will be larger if the outside diameter is kept the same.
As a result, a larger seatpost size is often a sign of a higher quality bicycle. This has resulted in a de facto standard of 27.2mm for high quality bicycles that have 1 1/8 O.D. seat tubes. Since high quality seatposts are widely available in 27.2, most high end aluminum and carbon fiber road bicycles also use 27.2.
