Does sitting on someone's wheel cause them to work harder than if they were out there on their own? I don't mean by being a "wheelsucker" and not helping them. I am talking about the physics of their aerodynamics. I heard hat it somehow wrecks their drag and creates a larger envelope of air for them to pull or something on those lines. I heard that teams will do this to someone who is a contender when they try to do a solo break. Anyone ever hear of this?
