Look at the Cannondale Six Series. A Six Carbon 5 gets you 105 Components and a BB30 crank (lighter/stiffer). All that for around 2k. Carbon will dampen the road vibrations a bit better than Aluminum. I'm riding a Caad9 1 and its not as harsh as I expected. I have had a bad experience with Trek and will never buy one again after dealing with their company.
