Assuming crank length indeed affects pedal stroke mechanics, can anyone convincingly argue that this supposed adjustment period is anything more than a myth perpetuated by the cycling industry to sell more cranks, or is it genuinely a physiological phenomenon that every rider must contend with.
Further, if a new crank length did necessitate a change in pedal stroke mechanics, wouldnt that imply that riders who successfully adapt to different crank lengths possess some sort of superhuman ability to rewire their muscle memory and redefine their biomechanics at will, or is this simply a matter of each rider finding a sweet spot that varies wildly from person to person.
Lastly, why do some proponents of crank length being a critical factor in pedal stroke mechanics claim that a difference of as little as 2.5mm can have a profound impact on a riders performance and efficiency, while others assert that the difference is negligible and that riders can adapt to virtually any crank length with minimal fuss, and which camp is correct.
