Whats the real impact of 160mm cranks on pedaling efficiency, and why do so many cyclists still swear by them despite the optimal crank length equation suggesting otherwise. Ive seen countless threads on this topic, but it seems like nobody can provide a straight answer.
Is it really just a matter of personal preference, or are there some underlying biomechanical factors that make 160mm cranks more efficient for certain types of riders. And what about the trade-offs between crank length, gear ratio, and cadence - how do these variables interact to affect overall pedaling efficiency.
Ive noticed that a lot of commuters and touring cyclists seem to prefer longer crank lengths, despite the fact that conventional wisdom suggests that shorter cranks are more efficient for high-cadence riding. Is this just a result of the fact that these riders often need to generate more torque to haul heavy loads or navigate steep terrain, or is there something else at play.
And what about the role of crank length in determining optimal pedal stroke and muscle activation patterns. Some studies suggest that longer crank lengths can lead to more efficient use of the hip flexors and knee extensors, but what about the potential downsides - increased stress on the knee joint, for example.
Id love to hear from some of the more experienced cyclists out there - whats your take on the relationship between crank length and pedaling efficiency. Do you think the benefits of shorter cranks are overhyped, or do you swear by the optimal crank length equation. And what about the potential for innovation in crank design - are there any new materials or technologies on the horizon that could revolutionize the way we think about crank length and pedaling efficiency.
