Mountain bike's first tuned carbon wheel system for enduro riding and racing.

Front and rear-specific rims provide an optimal balance of rigidity and flexibility, tailored to their respective advantages. Additionally, the inner rim widths for the front and rear are specially designed to accommodate wider and narrower tires, respectively.

Compliant Front Wheel:

The front wheel, fine-tuned for compliance, enhances handling and maximizes grip and control during turns. With a wider inner rim width, it supports a wider tire profile in the front, increasing volume and contact patch, resulting in a rounded tire profile that improves turning performance.

  • Lower Spoke count
  • Lighter Weight Spoke
  • Wider Inner Width
  • Lighter Rim


Stiff Rear Wheel:

The strengthened back wheel is optimized for handling high levels of force, promoting stability and precise tracking while in motion. A reduced inner rim width supports a thinner tire shape on the back, increasing efficiency and improving grip through sharper tire edges.

  • Higher Spoke Count
  • Heavier Spoke Weight
  • Narrower Inner Rim Width
  • Tougher Rim
