Manufacturer's Description

The new Eagle F1 is an “ultra-high-performance all-round road tyre” and the Eagle F1 Supersport, which is even lighter, is aimed at the upper echelons of competition and will be suited to road racing, time trial and triathlon where speed trumps all other requirements. The Eagle F1 boasts numerous technologies aimed at providing this desired high-performance. It has a 120TPI casing with R:Shield Protection, an anti-puncture belt under the casing. Over the top is wrapped the company’s own Dynamic:GSR rubber compound which is claimed to provide “improved grip, reducing rolling resistance and longer wear”.

Graphene has long been touted as the future and so far only a handful of companies have incorporated it into their products. In the tyre world, Vittoria has become well-known for adding the wonder material to its tyres for several years, and Goodyear has followed suit with its new rubber compound.

Goodyear has developed a proprietary compound enhanced with graphene and “next-generation amorphous (non-crystalline) spherical Silica” to create what it labels Dynamic:GSR. The result of all these fancy words is a rubber that is able to deliver the holy grail of low rolling resistance, improved grip in the dry and wet and long-term durability.

There are also directional tapered grooves and a smooth centre section which it claims to provide improved braking and cornering grip. The Supersport does away with these grooves to save weight.

The Eagle F1 comes in five width options from 23 to 32mm, while the Eagle F1 Supersport comes in three widths from 23 to 28mm. The Eagle F1 Supersport has a construction designed to optimise the rolling resistance and reduce weight but at the expense of puncture prevention and durability. The anti-puncture belt is narrower and the tread thickness has been reduced, measures which bring a 25mm tyre weight down to a claimed 190g.
