I'm a 6'9" 255 lb. clydesdale. I've been riding a road bike with ultegra hubs and mavic open pro rims. Next year I want to upgrade my ride to a custom tri bike with 200mm cranks, but I'm not sure which way to go with the wheels. Do Hed3's have any advantage over Zipp404 Clyde's? And, do disc wheels support riders that are 100lbs heavier than the average racer?
