The Continental DoubleFighter III Bike Tire IS light rolling and quiet on the pavement, yet grippy on tracks and gravel roads. Robust rubber sidewalls make it impervious to damage even over rough ground, making this the ideal tire for transforming an off-road bike to a nippy city racer. Textured center section rolls smoothly, aggressive shoulder lugs provide cornering traction. Fast rolling center tread provides low resistance on paved and gravel surfaces while providing outer progressive depth knobs for hard cornering. Durable mesh sidewall design with wire bead.
