In choosing a carbon fiber bidon cage for long distance touring, is the added expense of a high-end model worth the minimal weight savings, or are more affordable options just as reliable and secure. Some argue that the sleeker designs and advanced materials of premium cages make all the difference, while others claim that lower-cost alternatives perform just as well. What factors should I prioritize when selecting a carbon fiber bidon cage for my next long-distance tour - weight, durability, ease of installation, or compatibility with different water bottles. Are there any quantifiable benefits to spending more on a high-end cage, such as improved aerodynamics or reduced vibration, or is this simply a case of diminishing returns.
