Bicycle Rolling Resistance Coefficient. Tubeless vs latex vs butyl tubes. Rolling friction coefficients some typical rolling coefficients.
Since rolling resistance can be very small determining the coefficient of rolling friction is not an easy task. Despite rolling resistance only accounting for about 10 of the total resistance experienced by a typical ultra distance cyclist over an entire race different tire choices can make a significant impact on average cycling speed. 29 kmh 18 mph load.
