I have a perfectly good Caad 10 that I frequently race on. If I had one complaint about it, it is that the toptube is very wide, and because I ride with a lot of setback, the rear brake cable rubs against my inner thigh, and if I'm not paying attention, I sometimes bang my knee into the toptube. (It's one of the older ones without internal routing.)

I am now thinking of buying one of those Allez Sprint frames just because I like the color scheme.
