Specialized's Roubaix Pro 2BR is a 2Bliss Ready endurance road tire that's well suited for smooth and rough roads alike. That's because it's fast like any competitive road tire, only it features a unique Endurant casing with bead-to-bead puncture protection. The casing smooths your ride and keeps you fresh, while the tread handles responsively. Add to this the lower pressures and natural pinch-flat protection that tubeless setups provide, and you'll be hammering through corners confidently in no time. - Casing: 120 TPI - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - Flat Protection: Endurant Casing and BlackBelt - 700 x 30mm/32mm; psi 45-90; approximate weight 370g
