I'm 5'5" and I ride a 54 cm Specialized Ruby Pro and I absolutely love my bike. It climbs like a dream and absorbs so much shock from the roads that I swore some of my local streets were repaved. The Ruby line comes in 3 models, all carbon fiber. One comes with Shimano 105, one with Ultegra and the Pro comes with Dura Ace components. Of course, I swapped out the Dura Ace for Campy Record, but that's a whole other thread.
