Is it not time to challenge the conventional wisdom that deep-section wheels are inherently faster than shallow-section wheels at lower speeds, given the widespread adoption of disc brakes and the subsequent elimination of rim brakings aerodynamic impact. What empirical evidence, if any, supports the continued usage of deep-section wheels for general road riding, as opposed to solely time-trialing or other high-speed applications. Are we simply acquiescing to industry marketing or is there tangible, real-world data suggesting significant advantages to deep-section wheels in everyday riding conditions. Which wheel depth is truly optimal for general road riding, taking into consideration factors such as crosswind stability and rolling resistance. Is the notion of a single, universally fast wheel depth a fallacy, and if so, what factors should be considered when selecting wheels for differing riding styles and conditions.
