My time for each was about treefiddy.
Are you claiming the aero improvement is actually significant?
Are you claiming I can't find his claim to be dumb when paired with a very unaerodynamic frame and bike setup just because he is a talented cyclist who has completed long rides?
Like really, what is your point here because your response doesn't actually counter what I posted.
The guy's 'science' has been taken to task over and over again for years now. The guy's bike is objectively un-aero so doing a bunch of wind tunnel work to improve a specific area of airflow is...goofy.
On a related note- I have 35mm deep rims on a steel frame. Marginal gains despite starting at a distinct disadvantage to purpose built products can be seen all the time on bikes. Jan is ko different. If he wants an aero setup, then get a legit aero setup.
