Where did crank length come from? Where did these lengths that we consider “standard” originate? Has crank length just been passed down from one generation to another and over time has just become accepted even though there is no basis for the current “standard” with the current bicycles we ride today.
Optimizing your bike position, equipment, and setup is free speed. Not monetarily free, but free as in you’ll go faster without an increase in form or fitness. Athletes should check all the boxes. Buying a set of fast tires doesn’t mean you can take the week off from training.
