Tuned front and rear carbon wheel system for downhill riding and racing. Specific front and rear wheels that are tailored and optimized for the performance demands and stresses of mountain biking. A compliant, tuned front wheel enhances handling and maximizes grip and control in corners. A wider inner rim width supports a broader tire profile in the front, increasing volume and contact area while rounding the tire profile to improve cornering behavior. The stiff, tuned rear wheel supports peak loads and enhances stability and tracking at speed. A narrower inner rim width supports a slimmer tire profile in the rear, improving rolling resistance and sharpening the tire edge for better grip.
