Whats the current understanding of how crank length affects sustained Zone 2 climbing efforts, and are shorter cranks a viable solution for improving efficiency and endurance during prolonged ascents?
Is it still widely accepted that shorter cranks result in a higher cadence and reduced torque, and if so, how does this impact the overall energy expenditure during sustained climbing?
Are there specific physiological and biomechanical considerations that need to be taken into account when evaluating the suitability of shorter cranks for Zone 2 climbing, and how do these factors influence the decision to adopt shorter cranks for this type of effort?
