Specialized Roubaix SL4 Pro Disc Race Di2 (2015)

With a name like Roubaix, you’ll be sure of this bike’s sole aim, and the Roubaix SL4 Pro Disc Race Di2 certainly delivers. Superlight and strong FACT carbon frame & fork incorporating Zertz damping inserts to take the edge of bumps, while Shimano’s Ultegra Di2 keeps things moving forward. Roval Rapide carbon wheels running Shimano hydraulic disc brakes make a solid build for rider who frequents less than perfect roads.
