Bicycling Gear

The ideal road racing pedal stroke is smooth and efficient, maximizing power output while minimizing wasted energy and unnecessary full-body movement. Sport science research indicates trained cyclists perform best at cadences around 90 to 100 RPM, where aerobic efficiency and fatigue resistance are optimized.

Throughout the pedal cycle, different muscle groups contribute to power production. During the downstroke phase (1–5 o'clock), the gluteus maximus and quadriceps generate the majority of propulsion, extending the hip and knee to drive the crank downward. Around the bottom of the stroke (5–7 o'clock), the calf muscles, particularly the gastrocnemius and soleus, help transfer force through the ankle. During the recovery phase (7–11 o'clock), the hamstrings and hip flexors assist in unweighting (pulling upward) the rising pedal, reducing resistance against the opposite leg. Core muscles stabilize the pelvis and torso throughout the entire revolution, allowing efficient transfer of power to the bicycle.

Biomechanics and exercise physiology consistently demonstrate that a smooth, high-cadence pedal stroke distributes muscular workload across multiple muscle groups, reducing peak force demands on any single muscle. The result is improved endurance, lower muscular fatigue, and more sustainable power output, especially during long mountain climbs.

Enter the power meter integrated into the cycling pedal. Now a rider can read (on their cycling computer) real-time data, allowing you to make real-time adjustments to your form.

As you read through the Gear Score Cards, you will notice that not only is power output data available, but a full range of analytics is available in real time and for your post-race/ride analysis.
