Continental Grand Sport Race Road Tire The Continental Grand Sport Race Clincher Folding Tire is part of the Grand Sport family build on a solid 60 TPI casing, NyTech breaker and the durable and super grippy PureGrip tread compound. Conti have designed each tire for a particular use. The Grand Sport Race is designed as a balanced, all-around tire. The NyTech breaker and sufficient PureGrip compound in the tread give confidence for effortless and countless racing and training kilometres. Continental’s NyTech Puncture Protection has been developed based on the proven Continental SafetySystem Breaker. Its nylon fabric makes it resistant to punctures and cuts like Kevlar reinforced high strength fibres, but offers lower rolling resistance and reduced weight. The NyTech breaker sits between the SafetySystem and the PolyX Breaker as a more effective puncture protection casing in the performance sector. The PureGrip compound is based on activated silica compounds, this technology was originally intended as a performance level compound, but after intensive development at Conti’s Korbach Research and Development Department Facility, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self explanatory name “PureGrip”, is ranked just behind their BlackChili Compound and is being used in their performance products both in the road and mountain bike sectors. Whilst providing great grip, it is also long lasting and highly durable.
