You know that's not true. There is a reason why you have a 16.1lb Rossetti bike, right?
For a given amount of wattage, the newer bike will go faster because it has less air drag, and accelerate faster because it is lighter. That's just physics. It applies to the top flight riders and it applies equally to average joes.
