32” wheels only suit average height, white, male riders - my CAD drawing shows you why

Scott’s development of 32-inch wheels for gravel bikes, showcased by riders Cam Jones and Robin Gemperle on prototype models, has sparked debate within the cycling community. While these larger wheels promise faster rolling and improved cornering, their practical application remains limited. The company has emphasised that these bikes are not intended for commercial release, yet interest from wheel and tyre manufacturers suggests a push towards mainstream adoption of 32-inch wheels. However, the geometry challenges posed by 32-inch wheels on smaller frame sizes present significant obstacles. A detailed CAD study of a 54cm frame—typical for a rider around 5’8”—reveals multiple compromises, including extended chainstays, slack head angles, and limited space in the front triangle. These adjustments, necessary to accommodate the larger wheels, negatively impact handling, agility, and rider positioning. Moreover, the design struggles with toe overlap and clearance issues, making it impractical for smaller riders, particularly women and many Asian cyclists, who generally require smaller frames. The implications for the bike industry are considerable. If 32-inch wheels were to become mainstream, manufacturers would face the dilemma of either producing separate ranges for larger riders or excluding a significant portion of the market. This runs counter to recent industry efforts to streamline product lines and improve inclusivity. The lack of definitive evidence supporting the performance benefits of 32-inch wheels further complicates the case for widespread adoption, leaving the debate unresolved. Ultimately, the introduction of 32-inch wheels challenges both design norms and market dynamics within cycling. While they may offer advantages for taller riders on specific terrain, the compromises required for smaller frame sizes limit their accessibility and appeal. The industry must weigh these factors carefully before embracing larger wheels as a standard option, ensuring that advances in technology do not come at the expense of inclusivity and practicality.
