That's good to know; so at least one other person finds them fast. The 650C 23s are really skinny, though -- barely 22 mm on the 19 mm (outside) semi aero rims.
The 23s are fine on smooth pavements, and our pavement isn't that bad, at least where I ride, except for the huge expansion cracks due, I guess, to large low-to-high temperature differentials. I have to be careful about those. On Thu, Jan 2, 2014 at 5:25 PM, Jim Bronson <jim.bron...@gmail.com> wrote: > I love, love,love the ProRace3's on my go-fast bike!
