Race Day Competition 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. 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. This Eagle F1 Supersport has a narrower puncture protection belt and a slick centre tread section. This gives the Supersport the fastest possible rolling performance and is aimed at competition, being much suited to road racing, time trial and triathlon where speed is the ultimate requirement. 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 OPTIMISED TREAD CAP Reduced thickness and speed focussed tread pattern for ultimate performance Designed to perform 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.
