Specialized's Roubaix Comp is a zippy road machine that rides so smoothly and comfortably that you can't help but ride stronger and longer. Specialized's Zertz vibration-damping elastomer inserts boost the carbon frame's inherent road-smoothing qualities, while the back-friendly riding position means complete comfort and control. Plus, the 30-speed Shimano Ultegra drivetrain delivers the right gearing for every ride, while the Fulcrum Racing wheelset rolls effortlessly and is built to last. And, this carbon beauty comes with a full complement of Specialized's excellent aluminum components.
