SSS, it seems those who are writing on this thread may have their heads heads up the butt where the sun don't shine and therefore don't need any aero strap on's. One never knows what the advantages would be cause they can't see which direction they are going anyway. Sorta like the two wheel hero rider in Vegas that can't figure why the slinky don't work on the up escalator. I better go to the garage and do something before I go nuts.
