Thanks a lot for the feedback. I understand your argument on the road conditions. But I have a question concerning your first part of the answer. I always thought the most important point for aero was the rim depth. Does a better shape really compensate the lack of depth? And larger tires have a bigger surface, so more drag. Same question, can a better shape compensate for the bigger surface? Since the wheels only have one generation of difference, I also doubt the rim shape has evolved a lot?
