The Continental AttackForce Tire Positioning System is an innovation that racers have embraced because of the noticeable increases in response and handling. The Grand Prix Attack is an ultra light front race tire with Conti's 3330 TPI casing for great aerodynamics, low rolling resistance, and reliable high speed cornering. Plus, VectranBreaker technology features a liquid crystal polymer which results in a thread that is thermoplastic and therefore ultra puncture resistant.
