The successor to the highly popular Grand Prix 3000, the Grand Prix 4000 works on every road surface, transforming the demands of different styles of riding & supplies extremely long-term performance. It also achieves expectations in precision & production quality. The new puncture resistance. The Vectran breaker belt, developed & patented by Continental, surpasses even the famous puncture resistance of the former leader in this category, the GP3000. The extremely strong Vectran fabrics are more flexible & lighter than all other puncture protection materials. Vectran offers more resistance to cuts than Aramid, is five times as strong as steel & features less weight than a nylon double breaker. It also maintains strength in the wet. The compound. The black GP4000 tyre options feature the revolutionary Black Chili tread compound whilst the coloured options use advanced Activated Silica Compound (ASC) to increases the handling threshold & reduce the rolling resistance of the Grand Prix 4000 compared to the previous ASC compound. A new anti-cracking formula prevents UV light from damaging the compound & increases the mileage performance. The tread. Features tread wear indicators to help riders gauge the life of their GP4000 tyre. On the one hand you dont lose mileage performance by prematurely replacing the tyre & on the other you dont risk safety by using the tyre beyond its tread service life. Tyre Type
