This is huge.
Absolutely correct. I over simplified. And this is even more important if she has long legs, which it sounds like she does.
Given your last post, I would strongly recommend checking out Specialized, Terry (if you can, it's harder to find dealers) and Giant in the WSD models. Terry and Specialized tend to be a little shorter through the top tube. Giant and Specialized are good bang for your buck in terms of componentry. As mentioned previusly, if you can get an '07 model, better yet.
