The AERO 111 also incorporates all the winning technologies from the GP5000 TR Family: Black Chili Compound for superior grip and minimal rolling resistance, coupled with the trusted Vectran Breaker for added puncture protection. It’s the ultimate aerodynamic tire – without compromise.
The combination of all these features means on top of the low aerodynamic drag, the AERO 111 offers low rolling resistance, good puncture resistance and exceptional grip in both wet and dry conditions.
