I am looking at buying one of these. The Cannondale has an aluminum frame but better components (Ultegra, better crank). The Scott is an all carbon frame with 105 & better wheels. I love the look of the Cannondale. The Scott looks OK. The CAAD10 aluminum is supposed to be comparable to carbon on bikes in this class. What would you do?
