Considering the weight and stiffness benefits of modern cranksets, is it still worth investing in a 165mm crankset for Shimano Ultegra and Dura-Ace, or are the gains in terms of reduced ankle stress and improved pedaling dynamics outweighed by the potential drawbacks of reduced ground clearance and increased heel strike risk, especially for riders who prioritize comfort and practicality over marginal aerodynamic advantages?
Does the additional 5-10mm in crank length really provide a noticeable improvement in power output, or is this a case of diminishing returns where the added stress on the knees and ankles negates any potential benefits, and are there any notable differences in how Shimano Ultegra and Dura-Ace cranksets handle these issues, or is this more of a frame and riding style-specific concern?
Are there any data-driven studies or real-world examples that can help quantify the trade-offs involved in choosing a 165mm crankset, or is this still largely a matter of personal preference and anecdotal evidence, and what role do factors like rider height, inseam, and pedaling style play in determining the optimal crank length for a given rider and setup?
