Changing crank length to 165mm and not adjusting the gearing is it a recipe for disaster or a stroke of genius? Some argue that the increased leverage provided by longer cranks can be offset by a slightly easier gear ratio, while others claim that its a sure-fire way to blow your knees out.
Is it possible that this approach could work for certain riders or disciplines, such as criteriums, where the emphasis is on short, intense efforts rather than sustained climbing? Or would the increased stress on the knees and hips outweigh any potential benefits?
On the other hand, if one does decide to adjust the gearing, whats the optimal approach? Is it better to go for a slightly easier cassette, or to opt for a chainring with fewer teeth? And what about the impact on cadence - would a longer crank length necessitate a more deliberate, masher-style pedaling technique, or could a rider still maintain a high cadence with proper gearing and training?
Its also worth considering the role of individual rider characteristics, such as leg length, hip and knee flexibility, and overall pedaling style, in determining the ideal gearing setup for 165mm cranks. Should riders with shorter legs or more limited flexibility opt for a more conservative gearing approach, or could they still benefit from the increased leverage of longer cranks?
What are your thoughts on this topic - do you think changing crank length without adjusting the gearing is a viable strategy, or is it a recipe for disaster?
