High Performance All-Round Road The Eagle F1 R, part of the Road UHP (Ultra High-Performance) series, developed at the highest level of road cycling, is the tire of choice for racers and enthusiasts looking for low rolling resistance without sacrificing balanced grip on wet and dry surfaces. The road athlete who demands high performance and advanced technology, who seeks speed, demands cornering grip and puncture resistance. TRAIN - RACE - WIN - REPEAT Meet the next generation: the Eagle F1 R. Emerging from the Eagle F1, it uses advanced technology and all-new advanced compounds and fabrics for industry-leading all-around race performance.The Eagle F1 R is designed to provide optimum grip and speed thanks to the all-new Dynamic:UHP compound. Combined with the latest technology, such as short casing construction, the Eagle F1 R has a CRR reduction of 13% (@80psi). Tire type A clincher tire that functions only with an inner tube to maintain pressure, as defined in ISO 4223-1.The historic standard bicycle tire is based on the use of an inner tube to maintain tire pressure. The inner tube serves two purposes: maintenance of tire pressure and physical pressure on the tire bead against the rim hook and sidewall to keep the tire securely in place. Composition Dynamic:Ultra High-Performance A proprietary blend of synthetic and natural rubbers reinforced with next-generation graphene and amorphous spherical silica; our all-new Dynamic:UHP compound has been developed with the sole purpose of extending the "Magic Triangle" with improved rolling efficiency, traction and greater durability.
