Continental Grand Prix 4000 (700c Tubular)
Details
With the tried-and-true tread of the 4000 and the unbeatable ride quality of a handmade German tubular, Continental's Grand Prix 4000 Tubular is destined for greatness. Its seamless casing perfects the seating on the wheel for top-notch rolling resistance and easy mounting, and is super supple, too, for a velvety-smooth ride. Plus, this sweet sew-up has Conti's Vectran sub-tread for exceptional puncture protection, too.
Size: 700 x 22c
Vectran is a liquid-crystal polymer woven into the tire as armor against cuts, abrasions and impacts. It's also incredibly flexible to conform to the road's contours enhancing traction and feel. Finally, Vectran resists fatigue caused by repeated flexing, which lengthens the tire's life.
Continental's Black Chili rubber compound significantly improves wear, traction and rolling resistance through the use of carbon nanotechnology, microscopic carbon particles in the rubber. These mold better to the ground and have more points of contact, which gives the tire more grip. And, because the compound matrix is formed of more particles, which are connected more tightly with each other, the tire lasts longer. Plus, the smaller particles are more flexible, too, which improves rolling resistance.
