Mountain bike's first tuned carbon wheel system for enduro riding and racing. Front and rear specific rims offer stiffness and compliance characteristics where they are rewarded best, while front and rear-specific inner rim widths are optimized for wider tires in the front and narrower tires in the rear. Compliant Front Wheel: Compliant tuned front wheel improves handling and maximizes grip and control in turns. Wider inner rim width supports wider tire profile in front, increased volume and contact patch, and rounds tire profile to enhance turning. Lower Spoke count Lighter Weight Spoke Wider Inner Width Lighter Rim Stiff Rear Wheel: Stiff tuned rear wheel supports peak loads and enhances stability and tracking at speed.
