Isnt internal cable routing on a bike largely a matter of aesthetics, providing a cleaner look but offering little to no significant performance benefits? Or am I missing something? Ive always thought that the added complexity and potential for increased maintenance costs outweighed any minor advantages in terms of aerodynamics or reduced clutter. Yet, many top-tier bikes and component manufacturers are touting internal cable routing as a major selling point. What am I overlooking? Is there a tangible benefit to internal cable routing that Im not considering, or is this simply a case of form over function?
