One of the favorites of the Pro peloton, Conti's Grand Prix 4000 S II brings a host of innovations that roll faster with excellent control. The Black Chili rubber compound provides less rolling resistance with better grip, while the tread pattern on the shoulders increases traction through corners. A tough Vectran sub-tread offers exceptional puncture protection, while the 330-tpi casing delivers a velvety-smooth ride. If you're looking for the ultimate road tire, you've found it.
Vectran Breaker is a synthetic fiber modeled after spider silk. Processed into a multi-strand thread, it's light, flexible, and protects against cuts, without increasing rollling resistance.
Continental's Black Chili rubber compound improves every ride through the use of microscopic carbon nanoparticles to increase traction, decrease rolling resistance, and extend the life of your tires.
