Considering the vast array of crank lengths available, its astounding that the notion of crank length affecting gearing choices remains a topic of debate. Will switching to 167.5mm cranks necessitate a reevaluation of gearing choices, or is this simply a case of the emperors new clothes, with the cycling community being duped into believing that minute changes in crank length have a profound impact on performance?
If the answer is indeed that crank length affects gearing choices, then it stands to reason that the industrys standardization of crank lengths is nothing more than a farce, and manufacturers are simply catering to the whims of uninformed consumers. Conversely, if crank length has little to no impact on gearing choices, then why do so many cyclists swear by the benefits of bespoke crank lengths?
Furthermore, if crank length does indeed influence gearing choices, then what is the optimal crank length for a given rider, and how is this determined? Is it based on some arcane formula, or is it simply a matter of trial and error?
Its time to put this debate to rest and provide a clear, concise answer: will switching to 167.5mm cranks necessitate a reevaluation of gearing choices, or is this simply a case of the cycling community being led astray by pseudoscience and anecdotal evidence?
