I'm not an expert fitter, however, my wife is 5'9" and her "LG" Quick fits her, though it looks to me like she's pretty cramped on it. She says she's really comfy on it though and LOVES it. What does that mean to you? I don't know...other than I agree that TO ME, the guy who knows nothing about fitting, it looks like you're pretty cramped in the cockpit.

Your idea of riding a road bike on an extended test ride is a great idea. It will give you an idea if you prefer the style and are more comfortable on it.
