Does the conventional wisdom that shorter crank lengths reduce the torque output in Zone 2 actually hold up to scrutiny, or is this another case of cyclists parroting what theyve been told without actually understanding the underlying biomechanics?
It seems to me that the reduction in torque output is often attributed to the shorter crank length not allowing for the same level of hip and knee extension, but doesnt this overlook the fact that the riders power output is also influenced by factors such as cadence, muscle fiber recruitment patterns, and neuromuscular efficiency?
If we assume that a rider is able to maintain a high enough cadence to compensate for the shorter crank length, wouldnt the actual reduction in torque output be negligible, especially in Zone 2 where the rider is not yet at maximum intensity? And what about the potential benefits of shorter crank lengths, such as reduced muscle strain and improved pedaling technique, which could potentially offset any perceived losses in torque output?
Furthermore, dont the findings of studies on crank length and power output often conflict with one another, and arent these studies often limited by methodological flaws or small sample sizes? So, is it really possible to make a definitive statement about the relationship between crank length and torque output in Zone 2, or are we just speculating based on incomplete data?
Im not asking this question to stir up controversy or to provoke a reaction, but rather to genuinely understand the underlying science and to challenge the conventional wisdom that has been perpetuated in the cycling community. So, lets have a nuanced and informed discussion about the relationship between crank length and torque output in Zone 2, and lets separate fact from fiction.
