The fastest option in the Grand Prix 5000 tubeless tyre family. For the pure pursuit of speed, and already proven in both Dan Bigham & Filippo Ganna's successful World Hour Record attempts. The tyre of choice for Team Ineos in all TT and Team TT races.   Features Tubeless: Continental patented carcass construction is robust and impervious against damage from foreign objects. The result : versatility, lower weight and a super-attractive design. With this design, tyres can be used both tubeless or with an innertube. . BlackChili compound: Nano technology used to produce the carbon black particles that are used to reinforce the rubber compound. We refine special synthetic rubbers with natural rubber to create high performance tread mixtures. Taylored for the needs of the each tyre, in this case, more speed!. Lazer Grip, to make you one with the road. The lazered micro profile structure expands over the tire’s shoulder and provides outstanding cornering.. Vectran™: The benchmark in puncture protection Vectran™ is a synthetically manufactured high-tech fibre from a natural model. Like spider silk, Vectran™ is a liquid-crystalline polymer (LCP). Vectran™ is spun from the melted liquid polymer Vectra and processed further to a multi-strand thread. Spider silk like Vectran™ has an enormous tear resistance at a very low weight: Exactly the right properties to process into a premium Continental bicycle tire as a puncture protection insert. A Vectran™ Breaker is lighter, more flexible and protects more effectively against cuts than the comparable nylon breaker. Vectran™ Breaker does not adversely affect the rolling resistance..   Specification Bead: Tubeless Ready. TPI: 2/220. Weight: 225g (25c).
