One of the few tires that miraculously delivers on all fronts, the Continental's Grand Prix 4000 combines speed and amazing handling with impressive puncture resistance and extended tread life. The result is one of the fastest, most durable and best riding tires available.
Continental outfits this 650c tire with Black Chili, an incredibly dense rubber composed of particles roughly ten times smaller than what is typically used in bicycle tires. This state-of-the art material increases a tires ability to conform (grip) to the road, while also increasing durability. The Black Chili compound is also more resistant to UV rays, which contribute to cracking and premature tire wear.
Next, a Vectran puncture protection barrier has been placed beneath the tread. Originally developed by NASA in the construction of both space shuttles and suits, Continental has patented Vectran's use in bike tires, which allows their tires to remain extremely light, while offering tremendous puncture protection.
The Grand Prix 4000 features three fabric plies for a total of 330 TPI, has a Kevlar folding bead, a max inflation pressure of 120 PSI and weighs 205g. This version is available in 650c x 23mm (23-571 ISO).
