Physics of bicycle gears
WebbUsing BikeCalc we can determine the speed a bike will travel in each of the gear ratios by plugging in a cadence of 95RPM with a 700x44C wheel. We can then add the different rates of power (231 to 242 watts depending on gear ratio) as well as a rider+bike weight (85kg) into Bike Calculator* to find out the speed and time differences over 100km.
