This is the toughest road bike tire in its class. The Continental Gatroskin is the perfect ally to leave tire levers behind! It consists of a 180 TPI casing (3x60) but above all a PolyXBreaker reinforcement under the tread while the sidewalls benefit from Duraskin reinforcement right up to the sidewalls. Thus the risk of tearing is greatly reduced to allow you to enjoy your bike ride in all conditions. The performance is also quite excellent.
