? Why Is the Right Cadence Vital?
Knee Strain (Grinding)
Pedaling at low cadence in a heavy gear overloads the kneecap cartilage and quickly fills the leg muscles with lactic acid, causing early fatigue.
Gold Standard (Endurance)
It shifts the load from the muscles to the cardiovascular system (heart and lungs). This is the scientific secret to riding hundreds of kilometers without exhaustion.
Fast Spinning
Use it for rapid acceleration, sprint attacks, and the critical sections of steep climbs. It raises your heart rate.
