HOw big is your wife? I am 5-3 with a 29" inseam. QUOTE]

I am VERY short and my bike shop guy (who is WONDERFUL) was trying hard to get me into 700c wheels AND carbon. We tried the smallest Madone, because of the slopping top tube and WDS design. It came real close in fit, but my legs/inseam just tooooo short. Trek does a great job fitting small women. I tried a 44 Ruby--again 700c wheels. The upper body fit/reach was ok, but not quite right. I was still sold on Trek bikes. Believe it nor not I was fit for a Lemond Zurich, 700c wheels (yippee), carbon and really a nice ride. (diff geometry that an Trek, but alas still in the "family".) Not a bike many folks think about or ride, but easier to get hands on. Madone delivery takes forever. This small size Lemond came in less than a week. Price was good for the all components. Fit was perfecto!
The key is riding before you ride, not a luxury always for us small gals!

Good luck on whatever your decision is.
