The new Continental Sprinter Gatorskin combines the key features of Continental's very popular Ultra Gatorskin clincher and puncture protection Duraskin. If you love the feel of tubulars but want a more durable tire, this is the one for you. Perfect for getting the miles in during early season training when the roads are in the worst shape, or even racing when the roads are too tough for racing-specific tires. Removable core. Black with Duraskin sidewall. Max inflation pressure is 170 psi, 700c x 22mm (22-622 ISO), 300g and 700c x 25mm (25-622 ISO), 320g.
