I think that's what Merline is trying to say, yes?

Having said that, using aerobars on a bike designed for aero is ok, no matter what the distance. Its just that not all road bikes are designed to be ridden with aerobars because the aggressive seat angles cannot be achieved. Its the design of the frame.

Now, Cervelo's Soloist had a seat post that can be flipped to simulate a steeper angle. But still, Cervelo had its line of the "P series" of aero bikes.
