I also ride a Specialized Dolce. There are different models of them and according to my husband I am sure one of them is similar to the Trek. You would be staying with Shimano components instead of going to Campy's which I think that is what they use on Bianci. I am not too familiar with the Pilot, but if it is a road bike for comfort, than Roubaix as Spazzdog mentioned is in that catagory and also comes in different models. I did test the Allez 50 inch, I am 5'2" and although my leg stretch was fine, the reach was a bit more than I wanted. It might be worth going on the Specialized website and you can compare specs and components with what the Pilot offered you.

Hope this helps ~ JoAnn
