I have no idea what size my cranks are, but from reading this, I bet they're 165s (Trek 5200 WSD with 650 wheels). I was thinking the same thing about our collective height! I am 5' 1" (though I may have shrunk a bit?) and it seems like there are tons of people on this list that are my height... do you think there are more women cyclists who are short for any specific reason?
I just got back from a bike tour with Trek travel. The bike i used was the updated version of my bike (a Madone 5.2). Somehow, in updating the design, they managed to put 700 wheels on a 47 cm bike. I spent half of the trip getting used to the feeling of being higher up and the different feeling of turning with larger wheels. i did not like it at all! Maybe it's my poor spatial abilities, but I liked getting back to my own teeny bike with teeny wheels. A creature of habit, I guess.
