I just got my road bike a month ago, so by all means I am not an expert. I test road a Trek, Bianchi and Jamis. I had narrowed it between the Bianchi and Jamis and ended up with the Jamis Xenith Comp Femme. I love it! It is lighter than the Bianchi which I love! I am also 5'3 and I have the 48 frame.
