One of the favorites of the Pro peloton, Conti's Grand Prix 4000 brings a host of innovations never before seen in the world of bike tires. The tread pattern has been moved to the shoulders to increase traction in the corners. Tread wear indicators show the wear rate of the tire, eliminating guessing. The ultimate highlight however, is the use of Vectran. It's a polymer membrane that offers puncture protection and reduces rolling resistance, all at a race-ready weight. Also, the Black/Blackwall, Black/Transparent, Black/Reflex and Conti Yellow versions also contain Continental's Black Chili Compound for improved wear, traction and rolling resistance.
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.
