This is a great thread to resurrect. When buying my mtn bike last year I went back and forth about WSD. At 5'8" I can reasonably ride a vast majority of bikes. Nonetheless, my legs, while not supermodel long, are longer than they would be if I were a man, 31 inseam. Some of the men's bikes (it's not unisex, they're built for dudes) I test rode felt good. But nothing felt as good as Specialized's WSD, (Era). I will probably lean towards WSD bikes forever. Plus, I see buying WSD stuff as voting with your dollar, forcing companies to recognize that women ride bikes, buy gear, and deserve attention.
"I think it has done more to emancipate women than anything else in the world. It gives women a feeling of freedom and self-reliance. I stand and rejoice every time I see a woman ride by on a wheel...the picture of free, untrammeled womanhood." Susan B Anthony
