Pinas are definitely great bikes!! The thing that caught my attention is that the top tube lengths are pretty much the same between the two brands, although different models may change that a bit. ( for instance in the womens frame, size 48 the top tube length is 51.5, mens is 52-52.5 depending on model)

I too, thought that I'd never be a Cannondale person, but I can tell you that I have sold LOTS of them and own three now... of course with an eye for a new one as well.
