So what is the trick behind the use of shorter cranks? The difference certainly won't show while riding up the famous cobbled climbs of Tour of Flanders, however the a clear advantage is seen when a rider needs to maintain a higher cadence for a longer period of time - something
Tadej Pogacar would know a thing or two about with the amount of long solos he had pulled off in 2024...
This was also shown by a scientific study at the University of Utah in 2021. An advantage of a higher cadence is also that there is less muscle fatigue if you sit on the bike for three hours or longer. Contrary to the story about being able to pedal at a higher power for longer, this is not undisputed scientifically proven.
