1) Most importantly, there is no difference in body dimensions between men and women. If you look at a 5'1 man and a 5'1 woman, the average body dimensions are identical. Since women are shorter on average than men it appears to be a gender issue, but it really isn't, it's a short-person issue. So the trick is not to design women-specific geometry, but to make sure the geometry makes sense for shorter people. We do that, and every bike company should do that - one has to make sure that not only the geometry for a 56 or 58cm frame is properly designed, but also the 51cm and the 48cm.
