Built for the most competitive road bike by Specialized, the Roubaix Pro Tire clinches smooth and rough roads alike with fast, smooth-rolling veracity. It's slick at the center for low-rolling resistance, and shoulder sipes increase grip for greater surface adaptation when roads turn rough. Bead-to-bead casing enhances puncture protection, while BlackBelt technology enhances overall durability. Gripton rubber provides confidence-inspiring grip in all conditions without compromising rolling resistance or ride feel.
