Designed with the legendary Black Chili rubber compound, the Continental Grand Prix 5000 road bike tyre boasts a 10-gram weight reduction in a 25c width, a 12% reduction in rolling resistance and a 20% increase in durability compared with its predecessor. Thanks to the proprietary Laser Grip Technology which creates a micro tread pattern that expands over the shoulder of the tyre, the GP5000 also offers increased all-weather grip, giving you the ability to take even the most technical corners at speed. As a clincher tyre, the Grand Prix 5000 is also incredibly practical and easy to service at roadside too. Continental believes a comfortable tyre is a fast tyre – which is why the GP5000 now comes in a 32mm width and is constructed with Active Comfort Technology to help smooth the sharpest shocks from the roughest roads. Lined with the tear-resistant but ultra-lightweight Vectran fibres, the GP5000 sets new standards for puncture protection in road race tyres. So, whether you’re training in a downpour or racing in the sunshine, you’ll have complete confidence that your tyre out-performs the competition in every category and in all possible conditions.
