construction Tube Type A clincher tire that is only functional with an inner tube to maintain inflation pressure as defined by ISO 4223-1. The historical standard bicycle tire relies on the use of an inner tube to maintain inflation pressure. The inner tube serves two purposes: maintaining inflation pressure and providing physical pressure on the tire’s bead against the rim hook and sidewall to help keep it safely in place. COMPOUND Graphene-Silica-Road A proprietary blend of synthetic and natural rubbers enhanced with Graphene and next generation amorphous spherical Silica; our all-new Dynamic:GSR compound has been developed with the single purpose of expanding the ‘Magic-Triangle’ with improved Rolling Efficiency, Traction and increased Durability. The combination of Graphene, Amorphous Round Silica allows us to independently improve: Rolling Efficiency | 10.1%Traction| 8.0%Wear | 7.2% under-treadbreaker belt R:Shield This is a layer of additional puncture protection located under the tire’s tread cap.Tires utilizing our R:Shield under-tread belt offer excellent puncture protection while allowing the tire to remain supple, to maximize performance and comfort.
