Highlight
FEATURES
- Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight.
- Optimized carbon layup features high tensile strength carbon fiber placed at the most crucial points to provide stiff and lightweight wheels.
- A wind-tunnel-proven 40mm Hookless Rim Profile provides added aerodynamic advantage.
- Dynamic Balanced Lacing (DBL) technology makes a stiffer, more efficient wheel with outstanding power transfer, with the enlarged DBL hub flange increasing spoke bracing angles, boosting overall torsional/transmission and lateral stiffness for better power transfer.
- An increased rim bead width of 2.8mm on each side enhances rim bead stiffness, helping offer better support for tires when cornering.
- Designed for today’s high volume road tires, the 22.4mm wide inner rim width creates an increased actual tire contact patch, resulting in better traction and impact absorption for more confidence and improved ride feel.
- Giant low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance, and minimizing power loss.
- High tensile-strength aero carbon spokes on both front and rear wheels, reduce lateral flex for more effective acceleration and climbing, and purpose-designed aero form that provides great aerodynamic properties as well as superior stability in variable winds, all at the lightest weight possible.
