Grand Prix Supersonic - Faster than the speed of sound !

With the Grand Prix Supersonic, your wheels can be tuned to an absolute minimum weight and 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 recipie. But be cautious! The Grand Prix Supersonic is a very apt 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 PrixSupersonic is not a tyre for training! Revised 2011 model.

• 3 plies/ total 330 tpi + Black Chili Compound
