Why are you making decisions about gearing and fit, and asking us for fit, based on nothing more than the fact that she's a woman?

You're not designing a generic WSD bicycle, plastered in purple powder coat and sent to thousands of bike shops, to be sold to the esteemed Mrs. Generic Woman. You're building a particular bike for a particular person. This should be no different than building up a bike for a dude.

Make fit decisions based on her physiology and how she prefers to ride a bicycle. Make gearing decisions based on the sorts of routes you'll be riding, the load she'll be carrying, her strength, and how she prefers to pedal. Etc.
