The bike seems to be your size. I'm your height and prefer to ride 54s or 56s. But I'm opposite of you, I have long legs. Your inseam is a bit short for your height, but that'd typically mean you'd want a bigger bike, to accommodate your "longer than average" torso and arms. I think you're on the right size bike though. It'll just take a while to get it set up just like you want it.

However, the fact that you have to put the saddle all of the way forward is worrying. Maybe other's will chime in.
