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, Continental's quickest tyre and tube set weighs only 200g!
The slick rolling area made out of a carbon black mixture looks great and is of course made using the Black Chili recipe
A very apt weapon in fighting for personal best time, although for this extra speed the tyre does not feature any additional puncture protection and has limited mileage use
