I'd like to know too
I picked up the guide to womens saddles listed below, measured by butt region, let DH help me measure it again, and figure those sit bones are 7" apart. My saddle is 6.5" wide ~ purty sure that's not such a good fit

I haven't been to a shop yet to sit on other options - but did find a lbs that carries Specialized, think I'll start there.
