Building the Future Together: Reynolds and Sour Bikes Help Define the Next Wheel Evolution
The conversation around 32 inch wheels is growing quickly. But meaningful progress requires more than speculation. It requires rideable platforms, real testing, and true collaboration between the components that define a bicycle. At Reynolds, innovation has always been driven by performance on the trail, not theory alone. From industry first composite breakthroughs to decades of wheel development at the highest levels of racing, Reynolds has consistently embraced new challenges with a rider focused mindset. The emergence of 32 inch wheels represents exactly that: a new frontier.

A New Dimension Requires a Complete System
Wheel development cannot happen in a vacuum. Rim profiles, compliance, stiffness, tire interface, and durability must all be validated as part of a complete bicycle. That is why Reynolds, alongside Hayes Bicycle Group partners, has approached 32 inch development methodically, building physical prototypes and testing them in real world conditions. To do that properly, a frame partner was essential.

Enter Sour Bicycles
Based in Dresden, Germany, Sour Bicycles is one of the first builders to bring a fully developed 32 inch mountain bike platform to life: the Pasta Party 32″. Unlike large scale manufacturers constrained by the cost of carbon molds, Sour’s hand built approach allows rapid iteration and precise development. That flexibility makes them a perfect collaborator in defining what this new wheel size can truly become.

Real Testing, Real Progress
With the Pasta Party 32″ as a rideable baseline, Reynolds is able to explore the unique opportunities and demands of this new wheel dimension, from rollover characteristics to tracking stability, durability, and the balance of stiffness and compliance. The result is not simply a bigger wheel. It is the beginning of a better system, developed through partnership, craftsmanship, and performance driven engineering. The future of mountain biking will be built the same way it always has been: by riders, builders, and engineers working together, leaving no detail untouched.
