Our 15 year old just did the MS ride on a Jamis Coda Femme - http://www.jamisbikes.com/usa/thebik...codacompf.html

She's taller than your daughter, but is also all legs as well.

She didn't want a traditional road bike look because she also uses it to get around with her friends and the road bike (drop bars, etc.) isn't "cool". We got her pedals with SPD on on side and flat on the other so she used her bike shoes for training and riding the MS ride and can use sneakers to get around town.

We also put a rack on the bike so she can carry things. It is a great entry level bike.
