Challenge Grifo Open Tubular CycloCross Bicycle Tire

Open Tubular Tire's have the same construction and strengths as a tubular tire but are open to use with a clincher tire. When used with a latex tube you get the same great feel and grip of a full tubular tire. For riding in wet conditions. A special strip under the tread helps the tire be more resistant to punctures. Handmade for the highest performance when every detail counts
