When considering crank length in relation to power consistency, the general consensus is that a shorter crank allows for more efficient pedaling in higher cadence situations, while a longer crank is better suited for lower cadence, high-torque efforts. However, when it comes to Zone 2 efforts, which are characterized by a steady-state, moderate intensity, the relationship between crank length and power consistency becomes more nuanced.
Zone 2 efforts typically involve a cadence range of 80-100 RPM, which is relatively high, but not as high as the cadences often associated with shorter cranks. In this context, its unclear whether the benefits of shorter cranks in terms of power consistency would still apply. Would the increased mechanical advantage of a longer crank be offset by the increased muscle stress and decreased pedaling efficiency, or would the shorter cranks ability to reduce muscle stress and improve pedaling efficiency be enough to overcome the potential loss of mechanical advantage?
Do shorter cranks allow for better power consistency in Zone 2 efforts, or is the relationship between crank length and power consistency more complex and dependent on individual factors such as leg length, pedaling style, and fitness level?
