Building the Future Together: Manitou and Sour Bikes Bring 32" From Concept to Reality

There has been no shortage of discussion around 32 inch wheels. What there has been, until recently, is a shortage of truly rideable product. In any meaningful evolution of bicycle design, theory can only take us so far. CAD models and simulations are essential starting points, but bicycles are living systems. Frames do not get created without components, and components do not operate in isolation. A functional bike is a symphony of parts, each influencing the other. To truly understand what 32 inch wheels could mean for mountain biking, physical baselines had to be built. Enter Hayes Bicycle Group and Sour Bicycles.

From Screen to Trail

Manitou has been at the forefront of early 32 inch suspension development, with prototypes steadily migrating from paper and computer screens into real world testing. But prototypes require something essential: A frame. That is where Sour Bicycles became a critical partner. Based in Dresden, Germany, Sour is a small but highly respected builder known for precision craftsmanship, durability, and ride focused design. Their ability to hand build frames to exact specifications makes them uniquely suited to exploratory development projects where iteration and refinement are part of the process. While large scale carbon manufacturers must rely heavily on theoretical modeling due to the cost of molds and tooling, Sour operates with the flexibility to evolve quickly. That agility makes them an ideal co development partner.

The Sour Pasta Party 32": A Real Platform for Real Testing

With the introduction of the Sour Pasta Party 32″, Sour has reinforced its commitment to early adoption of meaningful innovation, always grounded in ride quality and durability. Based on their well known fast hardtail platform, the Pasta Party 32″ integrates the emerging wheel size into a production ready bike, not a concept or prototype. As Sour puts it: “Our goal was simple: take the benefits of the new wheel size and integrate them without losing the signature handling of the Pasta Party.” That philosophy aligns perfectly with Manitou’s own approach to suspension development.

True Co Development: Frame, Fork, and Wheel in Harmony

The collaboration between Sour and Manitou represents something essential for this new wheel dimension: integrated development. Fork performance cannot be defined without the frame, and frame geometry cannot be validated without the fork. Axle to crown, offsets, stiffness targets, tire clearance, and ride dynamics all evolve together through real testing. This is how meaningful innovation happens. Not in isolation, but through partnerships willing to invest in the work of riding, refining, and iterating. The 32 inch conversation is only beginning, but thanks to collaborations like this one, it is already rolling on real trails.
