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.
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%
Wear | +7.2%
Tires utilizing our R:Shield under-tread belt offer excellent puncture protection while allowing the tire to remain supple, to maximize performance and comfort.
