Proprietary design features all the benefits of a Tubeless Ready (TLR) tyre with additional air retention properties. Multi-compound material layer is added, allowing for improved air retention as well as additional puncture and cut protection. Functional with an inner tube to maintain inflation pressure Dynamic: GSR compound has been developed to improve rolling efficiency, traction and durability. Various fabric materials are formed with the casing to provide both cut and protection. R:Shield offers excellent puncture protection whilst the sidewalls remain supple to ensure high performance. EAGLE F1 Equipped with cutting-edge technology, the Eagle F1 has a single mission of all-round race performance at the highest level The Eagle F1, part of the Road UHP (Ultra High-Performance) range is the Ultra High-Performance all-round road race tyre. Optimized for outright performance favouring straight line speed and cornering competence - bringing factory performance to your garage. DEVELOPED FOR SPEED Developed from the ground up, the Eagle F1 range is the culmination of countless hours on the test drum, multi-surface closed test track, and the open road. The result is an evolution of technology with purpose. CONSTRUCTION Tube Type - A clincher tyre that is only functional with an inner tube to maintain inflation pressure as defined by ISO 4223-1. The historically standard bicycle tyre relies on the use of an inner tube to maintain inflation pressure. The inner tube serves two purposes: maintaining inflation pressure along with providing physical pressure on the tyre’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% % vs. standard compound Graphene up to 1 PHR UNDER-TREAD BREAKER BELT R:Shield - This is a layer of additional puncture protection located under the tyre’s tread cap. Tyres utilizing our R:Shield offer excellent puncture protection while their sidewalls remain supple to ensure high performance.
