Advanced Aerodynamics: Maximum aerodynamic efficiency for exceptional performance. Wide curved rim that minimizes air resistance, even with 28mm tires. Air resistance of only 8.9 watts at 45 km/h in a wind attack range between +/- 20 degrees. AIR+PLUS design for maximum bike control in side winds and gusts. Harness the wind to gain a significant aerodynamic advantage. High-Tech Construction: The material of the future, T1000 ultra-high modulus carbon fiber with graphene epoxy, the lightest discovered to date.
