The Roubaix SL4 Comp Disc is an all-day endurance beast that's the perfect upgrade for riders looking for more performance without spending a fortune. With its FACT 8r carbon frame and fork that feature our vibration damping Zertz inserts, along with the reliable performance of Shimano Ultegra components and disc brakes, the Roubaix SL4 Comp Disc will keep you fresher, longer.
The Specialized SL4 FACT 8r carbon frame has all the road absorbing, engineered compliance that you'd expect, while still providing all the responsiveness and performance you need for long days in the saddle.
The Specialized FACT carbon fork optimizes stiffness while providing excellent steering response. Road chatter is also absorbed through the Zertz elastomer inserts.
AXIS 4.0 Disc wheels provide plenty of control, tubeless compatibility, and all-day braking performance—regardless of the road terrain.
