Those look VERY nice. I am 5'3 and currently have a 50 cm Cannondale with 700c wheels. I wonder how it would be to go to the 650c wheels.
My girlfriend had 650 c wheels on her Trek 2300 but we found she was always the one to get TWO flats on group rides, and the rest of us have 700c so couldn't help out. She loves the road sparkles!
