GP5000: The Gold-Standard For Road Tires The Continental Grand Prix 5000 is a worthy successor to the beloved Grand Prix 4000 S II road tire, which reigned over the road-clincher bicycle tire market for over ten years. As you can imagine, creating a better version than the GP4000 was not a simple task, but Conti did it. The new Grand Prix 5000s are high-performing all-rounders featuring even better versions of Black Chili tread compound and tear-resistant Vectran Breaker technology, as well as two new technologies: Lazer Grip and Active Comfort.
