Developed specifically for racing and developed with World Tour teams, they are the fastest and highest performance Pirelli cycling tyre to date, they feature improvements in all the main areas; reduced rolling resistance, lower weight, and a revised TLR bead design:Patent Pending SpeedCOREtechnology consists of a thin air-tight layer of rubber compound infused with aramid particles. A reduction in the overall depth of the casing structure and a lower weight has resulted in a reduction of the rolling resistance compared to the P Zero Race TLR.The SmartEVO tyre compound features a blend of smart polymers inherited from our Motorsport expertise offering improved properties when measuring speed and grip, enabled by our new proprietary Made in Italy manufacturing processes. These qualities boost the handling precision and control to new levels, in both dry & wet conditions.A revised TLR bead design has enhanced air retention and offers greater compatibility to accommodate the latest rim
