Jen, if you are that short, 650c wheels are starting to be considered a good thing again. The womens world TT champ and Ironman champ both rode 650c bikes this year. Kind of sucks that you just bought new 700s for the roadie though. All you really need is a $100 disc cover for the rear wheel, and a cheap aero front would be easy enough to find. Wouldn't be too expensive.
