Building upon the original Ultra Sport, Continental has upped the entry level game once more with a value and performance based tire that's wrapped in a lightweight, supple casing and an all new compound for this price point. PureGrip Continental engineers, partnered with Korbach Research and Development, were able to take the standard active silica compound and further advance the technology to a new standard in grip and longevity for this performance level. It has been dubbed PureGrip, and that is exactly what it does. About Continental More than 100 years experience in the development and production of bicycle tires has made Continental a unique company within the industry. Continental is the only German bicycle tire manufacturer to produce its tires in Germany. Knowing this serves as a mighty incentive to their engineers and everyone else involved in the manufacturing process to constantly strive for further innovations. Continental's technology and development center, in Korbach, is constantly developing new revolutionary technologies such as the unbeatable Black Chili compound and the ultimate Vectran breaker anti-puncture technology, both used at the top end of race sport. These technologies demand sophisticated processes to ensure their legendary end-product quality, and these innovations as well as the ProTection and RaceSport technology for MTB tires, can only be manufactured in their factory in Germany – “Handmade in Germany”. In order to offer the best tire for any application, they rely equally on dialogue with their professional racers, hobby cyclists and everyday bike riders. As a global player, Continental also maintains high-tech production facilities outside of Germany, where Continental tires are produced for you with an equal degree of care and dedication. One thing all Continental bicycle tires have in common is that they are developed in the technology center in Korbach, Germany, where they also undergo strict inspection.
