Faster than sound! With the Grand Prix Supersonic, your wheels can be tuned to the lowest weight and rolling resistance. Together with a Race 28 Supersonic tube the tire weight for one wheel is only 200 g! Its slick profile and the BlackChili compound are the optimal combination for the lowest rolling resistance. But be warned. The Grand Prix Supersonic is a very sharp weapon in the fight for victory. Puncture protection is dispensed with for success. The tyre is designed for a limited number of race kilometres. The Grand Prix Supersonic is not a training tyre. He's tempted to top speed, but he doesn't forgive mistakes.
BlackChili - It's all in the mix The unique tread compound, which can only be produced in Germany, revolutionises bicycle tyres. BlackChili Compound improves rolling resistance by 26 % and at the same time offers approx. 30 % more grip compared to activated silica compounds. The premium tires with BlackChili Compound also convince with higher mileage and - in contrast to many multiple compounds - consistent driving characteristics from the first to the last kilometre.
super sonic This technology is characterized by low weight and maximum acceleration. Time trial and rail specialists benefit from the first-class rolling characteristics.
