Continental Sonderklasse II Track Tubular Tire

Black Beauty on the track - Sonderklasse II.
The Sonderklasse is the reference in indoor time trials. For generations a synonym for reliability – worldwide appreciated and hotly desired by drivers as well as mechanics.

Now Continental has optically updated the classic among the time trial tubular tyres. Presented completely in black underlines the special class even better and gives it a nobler image. The innermost values remain untouched: high value nylon carcass and the classical make-up in German handicraft.

BlackChili Compound
This unique tread rubber mixture which is only produced in Continental German factory has revolutionised bicycle tyres. The resultant compound showed a new relationship between grip and rolling resistance. This "Elevated level", as it was previously known, was given the name "BlackChili". Countless test wins that were shown in laboratory tests show a tangible benefit. The latest polymers, nanoscale soot particles and optimized fillers all guarantee a unique performance, from downhill MTB tyres to the time trial tyres of the ProTour, they are second to none in their respective areas. BlackChili Compound improves rolling resistance by 26% and provides 30% more grip than activated silica compounds. Premium tyres with BlackChili Compound also impress with higher mileage and unlike many multi-compounds, provide a constant ride from the first to the last kilometre.
