Think it could be better and now a days with the wide carbon rims 28 are better in terms of rolling resistance and aero (supposedly) so faster road riding.
I think HUNT for example say that their wheels are most aero with 28mm Pro One.
EDIT
I'd be looking for 19-20mm Internal, however looks like lightbicycle does 18mm on their 700c rims.
