Considering the rising trend of bespoke crank lengths and the importance of optimizing rider-specific geometries, can shorter cranks (sub 170mm) actually provide tangible benefits for taller cyclists in terms of improved pedaling mechanics, reduced muscle strain, and enhanced overall performance?
Specifically, would the reduced lever arm and resultant decrease in torque requirements lead to more efficient power production and a lower incidence of overuse injuries for taller riders, particularly those with longer femurs and potentially compromised pedaling dynamics?
Are there any empirical studies or data-driven analyses that have investigated the biomechanical effects of shorter crank lengths on taller cyclists, and if so, what were the key findings and implications for bike fit and equipment selection?
