Looty... yes, I was refering to the cadence portion of your comment. I think you were trying to say that a reduction in drag accounted for your speed increase at the same cadence... THIS can not happen. I am guessing though, you reduced the drag, and it was easier to spin, so you spun a little faster... thereby increasing your speed.

As one poster said, you are basically reducing the power required to go a certain speed when you reduce the drag.
