I just want to mention -- unless you've had WSDs before and been happy with them, don't assume they'll fit you.

When I was looking for a mountain bike, I came in looking specifically for a WSD frame. I figured it was cool that manufacturers were putting research into it, and I wanted to support that.

Anyhoo, I tried all three sizes of WSD for this frame, but the shop guy wasn't happy. He practically begged me to try the smallest unisex bike. Lo and behold -- it fit me like a glove.

Not every woman does well with WSD. Fit is very personal -- don't buy something without testing it out.
