A Pair Of The toughest 'performance' tyre on the market
With 23, 25, 28 & 32mm versions, the Grand Prix 4-Season makes it possible to select the right tyre for various road qualities, type of bike and comfort requirements. A double Vectran™ Breaker belt under the tread raises the puncture and cut protection to the highest level available on the market. Featuring a total of five plies beneath the tread, plus a sixth Duraskin layer, it's ideal for rough sportives and general bad road conditions.
"Puncture resistance is way above that offered by the fastest race tyres yet rolling resistance feels pretty similar. Grip is excellent, particularly in the wet."
