The Eagle F1 R Tube Road Tyre from Goodyear is part of the Road UHP (Ultra High-Performance) range, developed at the highest levels of road cycling and is the go-to tyre for racers and enthusiasts seeking low rolling resistance without compromising balanced wet and dry grip.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 pressureDynamic: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.Train, Race, Win, Repeat – It s race day, months if not years of preparation have bought you here. Like you, the Eagle F1 R has been in development for years. Technology underpins the evolutionary process with 3rd party data confirming leaps forward in performance. The Eagle F1 R is ready for the win Are you Developed For Speed – Introducing the next generation; the Eagle F1 R. Evolved from the Eagle F1, using cutting-edge technology and all-new advanced compounds and fabrics for class leading all-round race performance. The Eagle F1 R is engineered to provide top-of-the-line edge to edge grip and speed thanks to the all-new Dynamic:UHP compound. Combined with next generation tech such as short-ply casing construction, the Eagle F1 R boasts a reduction in CRR of 13% (@80psi).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 – Dynamic:Ultra High-Performance – A proprietary blend of synthetic and natural rubbers enhanced with Graphene and next generation amorphous spherical Silica; our all-new Dynamic:UHP 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 , +15.7%.Grip Centre, +19.0%.Grip Edge , +17%.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.
