The 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.
