The all-new Grand Prix 5000 Tire from Continental is a worthy successor to its Grand Prix 4000 S II, a tire that stood atop its road clincher tire range for a dozen or so years and a favorite among cyclists worldwide. What made the GP4000 so universally loved was that it was truly a competition worthy tire in terms of weight, grip, and rolling resistance, but unlike typical racing rubber, the tire was actually durable enough to fend off debris so you could train on it daily, while also lasting quite a while so you could rack up some miles before the threads began to show. As one of the world's largest tire manufactures, Continental has a host of technologies and compounds it can lean on giving it the ability to build the highest quality tires, hell the majority of the pro peloton rolls on them, and while we weren’t quite sure how Conti is able to create a road tire that's significantly faster, more comfortable, and less prone to flat than its previous version, somehow it did.
