I've been keeping an eye out for cyclocross bikes and frames, mostly to be used for commuting duties. They don't come up often and they aren't common in bike shops to take for test rides. And I would rather buy second hand for the price savings.
Anyway, I was under the impression that cyclocross frames were a bit more relaxed compared to your typical road racing frame. This is good for both riding in traffic (more upright) and just general comfort.
However I have recently been told by one bike shop that in fact they are quite aggressive and aren't really built with comfort in mind. And this was because CX races generally are only run for 1 hour or less, so comfort isn't a priority.
So which is it?
