Its surprising that despite the abundance of data on crank length and its effects on performance, theres still a lack of concrete evidence to support the notion that one crank length is universally better than another. Whats even more astonishing is that many cyclists and coaches still swear by the traditional 172.5mm crank length as the gold standard, despite the fact that human physiology is far more complex and varied.
Can someone explain to me why were still using a one-size-fits-all approach to crank length when its clear that factors like leg length, muscle fiber type, and pedaling style all play a significant role in determining optimal crank length? And what about the impact of crank length on different performance metrics, such as power output, cadence, and efficiency? Is it really possible to make blanket statements about the benefits of one crank length over another when the data is so clearly nuanced?
Furthermore, why do we always seem to focus on the extremes of crank length, with some advocating for super-short cranks and others pushing for ridiculously long ones? What about the middle ground? Wheres the data to support the idea that a 165mm or 170mm crank length isnt just as effective as the traditional 172.5mm? And what about the impact of crank length on different types of riding, such as climbing, sprinting, and endurance rides?
Its time to challenge the status quo and take a more nuanced approach to understanding the relationship between crank length and performance. So, Id love to hear from the experts and enthusiasts out there: whats the real story on crank length, and how can we use data to optimize our performance?
