In the price range of the Ruby, you could go custom and really treat her properly! If you're waiting until spring, take the time to search out a bike shop that can really fit her well with a Serotta fit bike or something similar. Read lots. Look at some of the non-big brand stuff. Perhaps buy a frame and order parts. Are you in an area with high end roadie shops? Might be worth a trip just to ogle non-big brand bikes to get a feeling of everything that is out there and she might find something really intriguing.
Your shop might also be willing to swap out the double crank to a triple but not sure if Dura Ace will shift a triple.
Hey girls, other carbon bikes to look at? Parlee, Calfee, who else? Seven makes a Steel/Carbon combo. Titus does an alu/carbon combo. All of these would solicite envious stares from others. Independant Fabrications - do they use carbon?
