A fact for all those wheel suckers!



A fact for all those wheel suckers!

A 69kg rider plus 4kg bike riding a 7% gradient at 14mph at that altitude with a drag coefficient of 0.65 and frontal area 0.4sqm will require about 370 watts of power. Of that, 50 watts is aero drag, so drafting someone in that situation will still save maybe 25w, worthwhile if you're on the limit!"
