What are the potential benefits for taller riders using 165mm cranks, and how do these advantages compare to the more traditional 172.5mm or 175mm crank lengths commonly used by professional cyclists. Specifically, do the reduced Q-factor and potentially increased power output associated with shorter crank lengths outweigh the potential drawbacks, such as reduced leverage and increased cadence requirements.
For example, if a rider is 64 or taller, would the use of 165mm cranks allow them to maintain a more efficient pedal stroke and reduced knee stress, while also enabling them to generate more power and speed. Conversely, would the use of shorter cranks require significant adjustments to their riding technique and training regimen, potentially offsetting any benefits.
Furthermore, are there any notable professional cyclists who have successfully used shorter crank lengths, and what were their experiences and results. Additionally, what are the implications for bike fit and component selection when using shorter cranks, and how do these factors impact the overall performance and comfort of the rider.
