Tuned Wheel System

Wheel stiffness maximizes power transfer and speed, delivering snap response and better tracking for confident cornering. Compliance enhances control and grip, reducing trail chatter and maintaining ground contact for faster, smoother turns. The solution is a perfect balance between a compliant front wheel for precise turns and a stiff rear wheel for ultimate power and tracking, creating the ultimate ride quality.

Improved Materials & Elevated Finish

Built from premium 6069 alloy, our rims deliver significantly higher tensile, yield, fatigue, and shear strength offering better resistance to dents, cracks, and deformation for unmatched durability and long-term performance. As for the shot peening, it strengthens the rim by hammering the surface in a controlled way, creating a hardened outer layer that helps prevent cracks and failures. As a result, Synthesis Alloy 2.0 has an improved bending strength, greater crack resistance, and a longer lifespan for better performance ride after ride.

Reinforced Rim Geometry

An updated rim geometry includes thicker rim walls in key areas most susceptible to impact damage, resulting in class-leading durability.
