I've thought about picking up a women's Paramount for my wife if I find a bargain. One thing I've noticed on those on eBay. The headtubes seem to be very long compared to the seatube, which would place the bars high for a "normal" amount of exposed seatpost. That is, it seems that if there were a toptube connecting the seatlug and headlug, it would slope noticeably upward from seatlug to headlug. I suppose this might have been done to raise the bars as Rivendell much more recently has advocated. Was there some other reason for this design feature? Did other makers of this type of frame do the same?

Does anyone have experience with "Woman's" frame (not mixte)
lightweights? They get no respect, but builders not known for
putting out floppy frames, such as Grandis

BTW I'd love to see links to others
I'm wondering if they performed significantly differently than the men's versions of similar bikes.
I also would like to know what size seat posts they used. (To estimate seat tube wall thickness.)
I'm thinking about building my wife a lighter frame.
I could build her another, lighter, mixte. But the article by Peter Weigle in this month's Bicycle Quarterly has me thinking about the relative merits of the Woman's frame vs. the Mixte. Most of the added rigidity of a Mixte over a "Womans" frame seems to be in the vertical plane.
One of the challenges of building a good frame is reducing vertical stiffness (within limits) without sacrificing torsional rigidity. A high quality seat tube can give significant vertical compliance without ever nearing it's yield point. I'm wondering if it might be better to invest the weight of the mixte stays in slightly heavier seat tube and chainstays.
This bike would be used for day trips or supported touring by a rider who probably weighs about 180 lbs and who never stands when riding.
