Are carbon fiber bidon cages nothing more than a marketing gimmick, or can they genuinely withstand the harsh realities of extreme weather conditions? Ive seen numerous manufacturers touting their carbon fiber cages as lightweight and durable, but what does that really mean when faced with torrential rains, scorching heat, or freezing temperatures? Can these cages maintain their structural integrity and continue to securely hold a bidon in place, or are they prone to cracking, warping, or shattering under stress? Ive heard whispers of carbon fiber cages being more susceptible to damage from UV exposure, moisture, and thermal shock – is this just a myth or a harsh reality? Its time to separate fact from fiction and get to the bottom of this. So, fellow cyclists, what are your experiences with carbon fiber bidon cages in extreme weather conditions?
