I share your dilema as I too am looking to get a new bike. I have been to several high end bike stores and heard allot of diffrent opinions. The Kuota Khan is highly regarded and an incredible bike. The Serrotta Ottrot st is also awesome but almost twice as much money. Another highly regarded frame set is the LOOK 585.The best value for the money is the Felt C1F. Several pro racers swear by this bike as the fastest ride they have ever been on. I hope to make my decision shortly and am leaning towards the Kuota Khan.
