Continental's Grand Sport Race Tires are a study in balance. Their NyTech breaker mimics KEVLAR's resistance to punctures but with a weight and rolling resistance that stay closer to the low levels we expect from racing tires. The Pure Grip Compound in their tread strikes a similar compromise, straddling the intersection of training durability, racing grip, and a price point that lets you run the tire for both applications without guilt. These features, combined with a 180 TPI casing, bring the Grand Sport Races to within 25 claimed grams per tire of the Peloton favorite Conti 4000 S II while nearly cutting the price in half.
