Developed for Speed The new Eagle F1 and the Eagle F1 Supersport models hug the road with the DynamicGSR compound, which combines Graphene and Silica. Between them, they increase both wet and dry grip while still rolling fast. Both of these F1 models use a supple 120tpi casing and Goodyear's R:Shield puncture protection cap. On this Eagle F1 the cap is a little wider, and the rubber on top of it is just a hair thicker but maintains the mild texturing making it a light, ultra-high performance, all-round road race tyre. DYNAMIC COMPOUNDING Dynamic: GSR - Graphene Silica Road - Improved Grip, Reduced Rolling Resistance and Longer Wear PROTECTION R:Shield - Improved puncture protection under the tread while maintaining overall performance DUAL INTEGRATED TREAD ZONES Keeping the driving and braking forces aligned properly as cornering forces come into play. Introducing the Ultra High-Performance range - A range of road race bicycle tires for superior on road grip and handling. Designed for performance at the highest level. The Story The Goodyear name first appeared on a tyre — a bicycle tyre, to be precise — in 1898. Since then, Goodyear and the legendary Winged Foot™ logo have been synonymous with victory, dominating the winner’s circle across the entire spectrum of motorsports. Goodyear tyres have shouldered heavy-duty work on everything from airplanes to Zambonis. They’ve rolled on the moon and have helped steer millions of motorists along their journeys. Now, 120 years after Goodyear's original offering, we welcome a new line of performance bicycle tyres. Developed with Rubber Kinetics, the Goodyear line utilizes refined compounds and casings, each purpose-built for their intended environments.
