the best bike and the worst were separated by where you choose to place your hydration. I've said this for some time - glad to see it backed up. That for the most part there really is not much difference between the best bikes. The ill-placement of a water-bottle on the bike has more impact on the aerodynamics than the frames themselves.
So could we also conclude that with the rather significant variable of riders-aboard the bikes (that has a much greater impact on overall aerodynamics) that really the differences in the frames are insignificant in the real world.
To be clear, the best bike and worst bike might have been separated by where we chose to place the hydration. In the front. The hydration tests we ran with behind-the-saddle bottle configurations did not add a statistically significant amount of drag one was basically half a watt lower and one was one watt higher (confidence interval about +/- 2 watts).
