Track cycling performance is dependent upon three major variables.
1. training for power, maximum cadence, and endurance.
Regardless of how and how much you train PowerCranks can help you to get more out of that time spent training. Track racing usually requires a trade off. A small gear optimizes acceleration but limits speed because high speed requires high cadences with low gearing. Cadence is limited, usually, by less than optimal coordination. PowerCranks train optimal, efficient, coordination to allow the rider to reach higher cadences. PowerCranks also allow the rider to easily experiment with optimum crank length as higher cadences are easier with shorter crank lengths. PowerCranks also train more muscles which allow riders to generate more power at low cadences and shorter crank lengths for better acceleration at low speeds.
Track racing requires a lot of different skills from very short high powered accelerations or sprints to sustained power for long periods in pursuit/time trials to long endurance in the Madison and six day races. Because track bikes are "fixed gear" bikes, track riders tend to ride at much higher cadences that road riders because of the need to balance both top speed and acceleration in one gear. PowerCranks can help the user develop all of these skills. Used by some of the best track cyclists in the world including Olympic medalists Miribella, Llaneras, and Roulston.
One track racer reported he was able to improve his maximum unloaded cadence from 180 to 240 and his max sustainable cadence to over 200 with 6 years of PowerCranks training.
