The new generation of PZERO Race TLR is the most performing tyre in our portfolio as well as being the first tyre with a tubeless technology entirely made in Italy. The introduction of the new SPEEDCORE technology in the 120tpi casing, features the use of a layer of rubber compound mixed with aramid particles which cover the inner layer of the tyre. The greater flexibility of the rubber compound improves the smoothness and cut resistance of the tyre. Result: a less stiff but faster tyre. The compound, on the other hand, maintains the same advanced SmartEVO technology, shared with the other high-performance tyres in the P ZERO range.Structure : SpeedCORE™ is an innovative tubeless-ready construction developed by Pirelli (Patent Pending) for our high-performance cycling tyres, representing our most advanced TLR technology to date. Derived from Pirelli automotive know-how and made possible by our newest production plant in Italy, nearby our Headquarter in Milan, SpeedCORE™ construction consists of a thin air-tight layer of rubber compound infused of aramid particles. This layer covers the internal part of the tyre and thanks to the presence of the aramid into the rubber blend, it allows for better mechanical resistance, improved air retention and overall greater flexibility: all contributing to the tyre's overall performance.Compound: Still our best chemical formulation for all-round road use, whether it means racing or high intensity and long distance leisure riding. It is born from the large Motorsport experience of Pirelli and the collaboration with the factory World Tour teams and it features a single-compound formulation based on three different polymers, each of which provides opposite performances in a perfect blend of grip, speed and reliability. The advanced mixture of polymers with 'smart' behaviours are the key elements of the SmartEVO compound, providing grip in any weather condition and very low rolling resistance in a package made to sustain also high mileage and rougher road surfaces. It is a high-performance chemical formulation developed for modern road cycling, from everyday riding to racing, even at World Tour level.Please refer to wheel / rim manufacturers website for tyre compatibility with hookless rims.
