Rolling resistance...
Well, shimano makes excellent hubs and freehubs that have very low rolling resistance. Same thing for campy. Rolling resistance of the hubs do make a slight noticable difference like when you are coasting down a hill with your buddy. In your case, the r550 has smoother hubs than the bontragers. But this is small when compared to...
... rolling resistance of tires. I believe that the attack force has lower rolling resistance than the gp4000 and hence they will roll faster. Combine this with a smooth hub, the r550/AF combo is surely gonna feel faster than your other set of wheels even tho they are heavier. Weight means nothing in the rolling ability of a wheel.
