Careful with that fit, if you are long torso short legs that could be exactly right, but if you are long legs, short torso that may be a bit big. You won't feel it until you've been riding for some time (like a few hours) so just sitting on it in the shop, or taking a spin around the block won't really do. I'm 5' nothing as well, they did try to talk me into buying a 48, but I really need a 44....... my legs are long enough to stand over a bigger bike, but my arms (and neck) are unhappy spending very much time on one.
