Classic competition tire for Cross Country or Marathon, versatile and smooth-running profile, for every terrain At the Research & Design department of Continental in Korbach, Germany is a permanent search for the solution to an old problem The rolling properties of the rubber of a bicycle tire are mainly determined by three different factors: grip, rolling resistance and service life.The dilemma:- Improving one characteristic often comes at the expense of another.- A tire with a lot of grip wears out faster and rolls slower.- But if the tire has to become faster, or has to last longer, this is at the expense of the grip.- A very good compromise has already been reached with the current, highly advanced technology based on ´´silica gel´´.- However, the engineers were not yet satisfied.- They broke new ground and achieved a breakthrough in the composition of the mixture:BlackChili compound is the name of the material for the tread, based on the latest knowledge of natural materials and polymers.Specifications:- Inch: 29 ´´- ETRTO: 50-622- TPI / EPI: 180- Maximum pressure: 4.5 bar- Maximum pressure: 65 psi
