I did win the auction, as well as that of an older step-through frame Raleigh that has been converted to a single speed so she will get to try two different ends of the spectrum. We also stopped by the LBS where they didn't have a large selection of bike that fit her, but she was able to try out a Trek 1.2 and 7.3 FX (both WSD.) She decided that she doesn't like STI levers (they're a long reach for her hands) and that maybe all-out speed isn't quite as important as she thought it was. She really wants something faster than a hybrid but more comfortable than a road bike: she wants a touring bike.

We did measure her inseam and I think she would be ok on either the 16" or 17.5" frame. The 17.5 would probably be a slightly better fit while riding, but standover height would start to become an issue. If some wider tires and perhaps some more relaxed bars aren't enough to make her comfortable on the 16" Symmetry, then I will continue to look out for a Madeleine/Classic. I will keep the longer stem suggestion in mind, especially if we swap the bars for something like the Nitto Albatross or a set of mustache bars.
