You will need something like a 62 to 64cm bike measured traditionally. Your problem is that most bike stores wont stock such a thing because the orders are few and far between for extra large bikes. You will have to be measured for fit and if you don't like the fit you will probably be stuck with it. It's well worth doing some homework before you walk into a store. Some options in large bikes are the Trek Domane, Emonda and Madone, Pinarello Dogma, Cannondale CAAD, and Cannondale Super Six for road bikes.
