Bicycle tires, inner tubes and tubulars

The new Continental GrandPrix 5000 is here. The GP5000 is made of 3-ply material with TPI 330 and the Black Chilli compound has been improved. The Vectran Breaker safety belt has also been upgraded, with puncture protection increased by 20% and weight reduced by 10g. The engineers at Continental have managed to reduce rolling resistance by 12% compared to the GrandPrix 4000 S II. Two new features have also been added, such as Active Comfort Technology, which is designed to absorb vibrations, and Lazer Grip, which provides better grip in corners.
