When it comes to the world of cycling, the recent buzz surrounding 32-inch wheels has sparked an intriguing debate. While some riders, like Cam Jones and Robin Gemperle, are raving about the revolutionary cornering and levitation these larger wheels offer, others, including myself, are more cautious. The idea that a bigger wheel rolls faster is an enticing theory, but is it truly a step forward for the sport and its accessibility?
In this article, I'll delve into the implications of introducing 32-inch wheels to the mainstream market and explore why it might be a backward move.
The Accessibility Issue
One of the key concerns I have with 32-inch wheels is their potential impact on accessibility. As someone who has designed and built bikes for decades, I can confidently say that the geometry of these larger wheels simply doesn't work for smaller frame sizes. This means that a significant portion of the cycling community, including many women and riders from Asia, would be excluded from this new trend.
Let's take a look at the numbers. A 54cm frame, which is considered a standard size in Western markets, would typically suit a male rider around 5'8" tall. However, this size is too large for the average Western female, who stands at around 5'4", and is considered a large frame size in Asian markets.
When I modeled a 54cm frame with 32-inch wheels in CAD, I encountered major issues. To preserve the stack and reach, which dictate a rider's position, I had to extend the chainstays significantly, resulting in a bike with compromised handling and agility. The head angle became extremely shallow, creating slow and imprecise handling, and the front triangle was so compromised that it seemed physically impossible to make it work.
The Business Dilemma
From a business perspective, the introduction of 32-inch wheels presents a challenging dilemma. If these wheels were to become mainstream, bike manufacturers would have to decide between producing 32-inch bikes for larger riders and maintaining the existing 700c sizes, or risking the exclusion of smaller riders, including women, who are already an underrepresented group in the industry.
Given the recent efforts by brands like Cannondale and Giant to streamline their product ranges and reduce the number of SKUs, it seems unlikely that they would embrace the complexity and potential exclusion that 32-inch wheels could bring.
Lack of Empirical Evidence
Perhaps the most frustrating aspect of this entire discussion is the lack of empirical evidence supporting the claim that 32-inch wheels are faster. While there have been some field tests and independent comparisons, the results are far from conclusive. Even if a 32-inch bike wins a race like Unbound, it doesn't prove that the wheels themselves are faster. It merely highlights the skill and speed of the rider.
A Step Backwards?
In my opinion, the push for 32-inch wheels in the mainstream market feels like a step backwards for cycling. It risks excluding a significant portion of the riding population and adds unnecessary complexity to bike design and manufacturing.
While I understand the allure of faster speeds and revolutionary cornering, we must consider the broader implications. Cycling should be an inclusive sport, and any innovation that limits access or creates unnecessary barriers is a cause for concern.
As we move forward, I hope the industry takes a step back and considers the bigger picture. Let's focus on innovations that benefit all riders, not just a select few.
