Is the traditional method of measuring the distance between the handlebars water bottle mounting holes to determine the correct size of a carbon fiber bidon cage truly the most effective approach? Or are we overlooking other crucial factors, such as the cages material properties, the riders hand size, and the bikes overall ergonomic design, that could significantly impact the cages performance and functionality? Furthermore, what role does the bidon cages shape play in terms of aerodynamics, weight distribution, and ease of use, and how can we strike a balance between these competing demands? Are there any innovative designs or emerging trends in bidon cage technology that could revolutionize the way we approach this often-overlooked component of our bikes?
