I will be in the market to purchase a new road bike this spring. My price range is up to $2000. My LBS sells Cannondale, Fuji, and Raleigh. I am 298lbs., and 6' tall. I have loved Cannondales my whole life, so I will definitely be going that route. My question is, which one? I will be using the bike mostly for general road riding, commuting once in a while, and a century or two this summer. I would like something comfortable, but not geriatric feeling. I was originally looking at the CAAD9 because of countless excellent reviews, and with it being made in the USA really is appealing. I started looking at the Synapse and Six series lately too, and am not sure how I feel about carbon. I know it is the latest and greatest thing, but is it really better than C-Dale aluminum? I really had my choices narrowed down to the CAAD9-3 or the Six Carbon 6. What do you guys think?
