I just started working for a large chain bike shop. A woman and her husband came in looking for entry-level road bikes. He was 6'2", she was 5'1". We had nothing in road bikes for her, because we don't seem to have a 44cm on the floor, and maybe one that would fit him. It sucks from both sides : You can't get what you need (I've been there too), and they can't help you get what you need , which is disappointing. Sadly, if you don't fit within a certain range of sizes and proportions, bike shopping sucks.
