Ladies bikes

I'm just being annoying.

In fact maybe you can advise. I have been informed according to Adultdata from the DTI whatever way you measure it, average ratio of legs to stature is near enough identical between men and women. So how come we need shorter top tubes?

I have been told it's to do with pelvis but I reckon it's arms. Maybe I just have short arms though.

I've heard various theories concerning this. There could be a shoulder factor involved (men using their wider shoulders to stoop forward, making it possible for them to use longer top tubes), or pelvic factors could mean that women are less at ease bending forward as much as men when achieving a sporty position (although that obviously has a lot to do with fitness). Ultimately, I suspect that, strangely enough, women are just as varied as men are in their body geometry. :)
