FurryBlue - I think you did a very good job of explaining the effect of seat tube angle on cockpit length and how it plays into reach. I also liked the way that you explained how top tube length is important as it affects (with the head tube angle) toe overlap. But all in all, top tube length is a huge component of reach and the concerns these women have about the reach of these frames seems justified.
