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.
ok my post was a bit more snarly than needed, mea culpa
I guess I don't understand the dissing of Jan. yes he is iconclastic bordering on eccentric, and I don't buy everything he does, but I do think he is sincere and he bikes the talk himself, but is not a luddite.
His bigger tires are not slower (to some logical point) have been embraced by tour de france riders with many riding 30mm (with more like 32 measured tires)
his moto style fenders for aero, are not for sale so he is not hawking that
his focus is long solo rides like the long gravel rides and paris-brest-paris so aero is in that context of having to bring things along
but the key point is he rides what he is pitching, and gets some top times. Is it the rider, the experience the gear? as always a bit of both. will it work for everyone, probably not....especially super thing flexy frames and bigger riders like me
