Not sure this is the best forum but it is the most technical.
Anyway today I rode on the flat into a 20mph+ headwind doing about 10mph.
So aero drag is equivalent to doing 30mph and should totally dominate.
Fact is I can't remotely do 30mph on the flat no wind, around 20mph, so how can
I do 10mph into a 20mph wind ? Coming back the other way with the wind I think
I hit 25mph maximum on the flat, how does that work with a 20mph tailwind ?
Before you say the wind simply wasn't that strong I can assure you it was.
