These new clincher tyres from Continental are designed for riding fast against the clock and were used by Tony Martin when he won this year's World Time Trial Championships.
They offer low rolling resistance and a light weight of 170g each. Their slick surfaces are like the ones you see on Formula 1 racing cars, offering unparalleled grip until it rains.
The rubber is made from Continental's soft and tacky BlackChili compound, with a thin Vectran belt that runs underneath to protect from flints and thorns. Like all fast and light tyres they're best saved for short dry races on good roads.
They might help you shave a few seconds off your PB, but they won't cope well with wet weather and gritty roads. Don't expect them to last long if you're using them every day.
