The 2nd generation of pzero race tlr is our most all-round model in the p zero family as well as being the first tire with a proprietary tubeless technology entirely made in italy. - the patent-pending speedcore structure features a 120tpi carcass along with a layer of compound reinforced with aramid particles: this unique blend of polymers deliver not only complete airtightness but also a strong resistance against punctures without stiffening the whole structure. - the smartevo compound adds then grip and mileage in all conditions dry and wet and it does so with its content of natural rubber fully certified fsc® another milestone that pirelli introduced in 2024 in all its bicycle tires made in italy. The result is a reliable comfortable and fast tire all in one ready for world tour racing as well as long distances on daily training rides.
