The Grand Prix 5000 TT TR tire is ideal for time trials and has been specially developed for the fight against the clock. It is still one of the fastest and most popular road bike tires. As the fastest tubeless tire in the Grand Prix 5000 range, it's perfect for speed lovers. It is ideal for time trials or triathlons. The abbreviation TT does not stand for time trial for nothing. In addition to its high speed and good puncture resistance, the tire also impresses with its low weight, which ensures improved acceleration. The Grand Prix 5000 TT TR is also compatible with hookless rims. Handmade in Germany Over 100 years of experience in the development and production of bicycle tires make Continental a unique company in the industry. Continental is also the only German bicycle tire manufacturer with production in Germany! Conti tires are built by hand in Germany using unique technologies and materials. Black Chili Compound At Conti, BlackChili means above all that grip, rolling resistance and durability are combined at a level that makes you almost believe in magic. Continental simply uses the very latest and best technologies. The latest polymers, soot particles and fillers optimized down to the nano range guarantee the unique performance of the BlackChili compound. It revolutionized the basic conflict between grip and rolling resistance. Approx. 30% more grip and a 26% improved rolling resistance compared to the silica compound ensure better performance and safety. Continental tires consist entirely of this high-quality rubber compound. Thus, the tires can be worn down to the carcass without losing the first-class properties of the rubber! Anyone who has ever driven a tire with Black Chilli would not want anything else! Vectran Breaker Vectran is a synthetically manufactured high-tech fiber based on a natural model. Like spider silk, Vectran is a liquid crystalline polymer (LCP). Vectran is spun from the molten liquid polymer Vectra and further processed into a multifilament yarn. Spider silk as well as Vectran have an enormous tear resistance with the lowest weight. A higher puncture resistance and lower weight are the advantages of the Vectran breaker. Vectran is more cut resistant than aramid, 5 times more tensile than steel and lighter than nylon thread without affecting rolling resistance. Thus, it offers the ideal protective layer for the tire. Vectran was developed for airbag systems in the automotive and aerospace industries. Tubeless The TL technology is specially designed to adapt tubeless to the demands of road cycling. Easy to assemble and reliable in use. Specially developed, the tubeless foot seals with its shape and ensures a stable hold on the rim. Active Comfort Technology The revolutionary approach to road cycling. Integrated into the tire construction, the Active Comfort technology absorbs shocks and ensures an outstanding driving experience. Laser grip Lets you become one with the street. The lasered micro profile structure focuses on the shoulder area of the tire and offers you increased cornering grip. NOTE: Tire pressure must not exceed 5 bar (73 PSI) on hookless rims. Continental recommends using at least 30 ml of suitable tubeless sealant for the initial assembly.
