EAGLE F1 R The Eagle F1 R, part of the Road UHP (Ultra High-Performance) range, developed at the highest levels of road cycling, is the go-to tire for racers and enthusiasts seeking low rolling resistance without compromising balanced wet and dry grip. TRAIN - RACE - WIN - REPEAT '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.
