Whats the logic behind adjusting bar width in conjunction with crank length changes, and are there any established guidelines or research-backed recommendations for doing so? It seems counterintuitive that a change in crank length would necessitate a change in bar width, as the primary function of each component is distinct. Crank length is typically chosen based on factors like rider leg length, pedaling style, and terrain, while bar width is often determined by rider preference, shoulder width, and handling characteristics.
That being said, some riders swear by the idea that a change in crank length requires a corresponding adjustment to bar width in order to maintain optimal ergonomics and handling. But is this simply a matter of personal preference, or is there a more nuanced relationship between these two components that warrants a more thoughtful approach?
For example, if a rider switches from a 170mm crank to a 175mm crank, should they also consider widening their bars to compensate for the increased leverage and altered pedaling dynamics? Conversely, if a rider switches from a 42cm bar to a 44cm bar, should they also consider shortening their cranks to maintain a balanced riding position?
What are the key factors to consider when adjusting bar width in response to crank length changes, and are there any specific scenarios or riding styles where this is more critical than others?
