46 CM comes in 26" not 700C wheel size.
nothing wrong with that, you are more likely to get a spare tire in Ushuaia
in a 26" than a wide 700c. being short, riding that small a sized bike frame
is tough to adapt to a larger wheel ,
the geometry gets wacky .. steep seat tubes, low angled head angles
to get any room for your toes , Or Ms Terry's solution 2 wheel sizes..
fitting a pair of 1.5" wide tires will roll just fine..
Guess I'm a retro grouch, but I don't like the look of disc brakes on a road bike.
You'll barely know they're there, hidden behind the 4 stuffed Panniers and such..
