I assume a lot of the pros choose rim brakes to save weight. Contador used mechanical groupo until very recently IIRC to save that 200g of weight on mountain stages. When you have to climb 3 everest mountains every grand tour, the lightest bike is the way to go. I assume the same for aero bikes, i have not seen 1 aero bike in any size that's even close to 6.8kg. Until disk brakes become lighter than rim brakes, pros are going to stay with rim brakes.
