I have the CAAD 12 dura ace disc, so any specific questions, please feel free to ask.
It rides much more like my carbon bike than my other alu bike i.e. Smooth.
I have tinkered with it a little and it now has fulcrum Quattro carbon disc wheels among a few other minor changes. I like it very much and am planning some longer rides on it, including the double Dun Run, so 200 miles+
Mine weighed 8.3kgs when bought, with pedals fitted, so light but not the lightest. I am guessing mine probably just gets under 8kgs now having shaved 250grms from wheels and some from saddle etc.
Loke it a lot and think it is a very good bike.
