Biophysics of Cycling Speed and Aerodynamic Power
On flat roads, the primary force resisting cycling speed is aerodynamic drag. The power required to overcome drag increases in proportion to the cube of your velocity (Power ∝ Velocity³). This means going slightly faster requires significantly more effort. Mechanical efficiency is also dictated by tire rolling resistance and drivetrain friction. Maintaining an optimal pedaling cadence of 80 to 95 RPM reduces torque demand on your knee joints, shifting the physical burden from skeletal muscle fibers to the highly efficient oxidative cardiovascular system.
