I just got a Surly Long Haul Trucker and I was amazed at how 'small' a frame I required! I bought a 46. My road bike is a 50cm women's specific design. I had to get over the 26" wheel thing, but I really like the bike. It's geared for carrying a load (more like a mtn bike than a road bike). I climbed some serious hills on it this weekend, and only went into the smallest chain ring (front) two times. Other than that, I stayed in the middle chain ring and it was fine. It rides well loaded down and looks cute with fenders Obviously, I'm biased since I bought the thing and feel compelled to like it, but I really do like it and it is equally good for commuting as for touring... JMHO
