As our entry point into the Roubaix line (and to carbon road bikes in general), we want the Roubaix Sport to deliver a smooth and lightweight ride without breaking the bank too much. We’d like to think it does just that. Shimano’s 105 group is always a hit with bike shop employees (it works really well and doesn’t cost too much). Specialized’s Roubaix frame is the endurance frame that launched a thousand replicas. Put these two together and you’ve got quite the solid ride.
