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. The German tire manufacturer focused specifically on the two problematic areas of the GP4000s — cornering grip and puncture protection. With their added tech in both these departments, the GP5000 rises above all other comparable clinchers. The Vectran Breaker puncture protection is lighter, is more flexible, and protects more effectively against cuts than the comparable nylon breaker used in previous models. Like spider silk, Vectran is an extremely strong and lightweight synthetic material, woven tightly into a multi-strand barrier. The GP5000's Lazer Grip technology delivers more cornering traction from day one — no break-in time is required thanks to its micro profile structure that reaches over the shoulder of the tire. Integrated into the 3-ply/330tpi casing of the Grand Prix 5000, Active Comfort technology provides stiffness in the sidewall and flexibility under the tread for greater vibration dampening and excellent ride comfort. New for 2021 are two additions to the Grand Prix 5000 tire family that will add flair to your tarmac trophy bike or radical racehorse: A cream sidewall modeled after Continental's commemorative Tour de France edition (but without the race's branding) and a throwback brown sidewall that Continental has dubbed "transparent," so-named because the tire's "carcass is visible under a transparent coating."
