I'm 5' 3.5" and ride a 51 cm Ruby. I have a 30" inseam, short torso, and a long reach. My previous road bike was a 47cm Allez which fit pretty well. The other think I love about the Ruby is the way the bars are sized for a woman. You mentioned that you have small hands, so you will love the way the bars are sized and shaped. I can ride the hoods and reach the brakes/shifters or I can ride in the drops and reach them as well.

I'm willing to bet that you can be fit on a Ruby.
