Continental's Grand Prix 4000 S boasts Conti's Black Chili rubber compound for 26% less rolling resistance, 30% more traction and 5% longer wear (than previous Grand Prix 4000 tires). This makes for one of the fastest tires in the peloton. Even better, the GP 4000 boasts a tough Vectran sub-tread for exceptional puncture protection, a 330-tpi casing for a velvety-smooth ride, and tread-wear indicators to eliminate guessing. If you're looking for the ultimate road tire, you've found it.
Vectran Breaker is a synthetic fiber based on the natural model of spider silk. Processed into a multi-strand thread, it's lighter, more flexible and protects more efficiently against cuts than a comparable nylon layer. It also does not affect the tire's rolling resistance.
