The Eagle F1 RS is our all-round road race tire developed to perform at the highest level of cycling, utilizing a new Power Tensile polyamide casing material, UUHP Compound, Advanced Profile construction, and R:Shield puncture protection. The evolution of our cutting-edge technologies results in a 32% reduction in rolling resistance (at 72 psi) compared to the previous Eagle F1R. This 4.8-watt reduction in rolling resistance combined with improved grip and durability characteristics results in class-leading performance.
