Faster than the speed of sound!

With the Grand Prix Supersonic your contact with the road can be tuned to minimum weight and minimum rolling resistance. Together with a "Race 28 Supersonic" inner tube, our quickest tyre weighs only 200 g! The slick rolling area made out of a carbon black mixture looks cool and is of course made using our Black Chili recipe. But be cautious! The Grand Prix Supersonic is a very atp weapon in fighting for a personal best time, although for this extra speed, the tyre does not feature any additional puncture protection and has limited mileage use. With this in mind, The Grand Prix Supersonic is not a tyre for training! Revised 2011 model.
