Whats the logic behind the assumption that shorter cranks are inherently beneficial for improving pedaling technique at Zone 2, and why do so many coaches and fitters recommend shortening crank length as a solution for inefficiencies in a riders pedal stroke when the primary limiting factor in most cases is likely to be a riders inability to properly engage their core and upper body in the pedaling motion, rather than any inherent biomechanical issue related to crank length.
Isnt it simplistic to attribute poor pedaling technique solely to crank length, rather than examining a riders overall fitness and technique, including their ability to maintain a consistent cadence and apply even pressure throughout the pedaling motion. And given the highly individualized nature of bike fit and the significant variability in body proportions and riding styles, shouldnt we be cautious of making blanket recommendations about crank length without also considering a riders specific needs and riding position.
Furthermore, how do we know that a rider who switches to shorter cranks will actually improve their pedaling technique, rather than simply adapting to the new crank length and continuing to ride with poor form. And what about the potential drawbacks of shorter cranks, such as reduced leverage and power output, which could be particularly problematic for riders who rely on a strong pedal stroke to propel them uphill or over long distances.
Can we really say that the benefits of shorter cranks are worth the potential trade-offs, and shouldnt we be focusing on more holistic approaches to improving pedaling technique, such as core strengthening exercises, flexibility and mobility work, and targeted drills to improve pedaling efficiency and endurance.
