joann... there's a huge difference! i have a dolce elite (04) and the ruby pro is MUCH smoother on the roads... i'm sure it's a combination of the carbon frame... zertz inserts and carbon handle bars!

and of course the whole bike is lighter!! i was really surprised though, when i picked up the ruby comp in the store... it was actually "heavy"! but the lbs guy was telling me that the carbon used to make the pro frame is even lighter than the carbon they use on the s-works!

however i LOVE that you see the weave on the comp (black) and elite (blue)versions... the carbon on the pro is different and you don't see that distinctive weave! especially the comp... but that's cuz i love black bikes!
