We run the Grand Prix 4 Season Clincher Tire for unpredictable racing and training conditions when we need a little extra flat protection. The secret to this tire's puncture resistance is the Vectran belt which lies under the tread, a liquid-crystalline polymer that is extremely tear-resistant yet impressively lightweight. The unique tread pattern offers enhanced cornering grip in wet conditions, yet accelerates quickly for competition use.
