The Grand Prix 4 tire features a 330TPI (threads per square inch) double layer Vectran belt under the tread. This proprietary fabric is a liquid-crystalline polymer that features high levels of tear resistance at a low weight, making it ideal for racing as well as training. To take the Grand Prix 4 to the next level of rider satisfaction and beef up puncture resistance, Continental reinforced the sidewall with DuraSkin, a polyamide fabric that keeps road grit and grime from penetrating to the tube.
