What do road bike tires and the space program have in common? When you're talking about the Continental Grand Prix 4000 tire, it's Vectran fluid crystal fibers. Developed initially for the aerospace and automotive industries, these marvels of science are used by Continental to create an exclusive Vectran breaker -- a reinforcing belt -- that gives the Gran Prix 4000 low rolling resistance, excellent handling characteristics, and resistance to punctures and cuts. Fast, grippy and resilient, Grand Prix 4000 tires are like jet fuel for you bike.
