With the Continental GP Supersonic 700c Folding Road Tyre your contact with the road can be tuned to minimum weight and minimum rolling resistance. Together with a ”Race 28 Supersonic” inner tube, Conti quickest tyre & tube set weighs only 200g! The slick rolling area made out of a carbon black mixture looks cool and is of course made using our BlackChili recipe. 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 Prix Supersonic is not a tyre for training!
