The S-Works Roubaix SL4 Disc Frameset was born from the cobbles. With multiple Paris-Roubaix victories, not to mention countless other wins on some of the roughest roads that professional cycling has to offer, the S-Works Roubaix has proven itself time and again as the gold standard of endurance race bikes. The exclusive S-Works SL4 FACT 11r carbon frame and fork are legendary for the seamless combination of instantaneous responsiveness and engineered compliance, and they're just waiting to be a part of your dream build.
- Our highest grade, exclusive S-Works SL4 FACT 11r carbon frame is equal parts stiff, responsive, compliant, and smooth, thanks in part to its compact race design and vibration damping Zertz inserts.
- The Specialized FACT carbon fork comes in three different sizes with varying steerer diameters that optimize stiffness for that size, while also providing excellent steering response. Road chatter is also absorbed through the Zertz elastomer inserts.
- FACT carbon CG-R seatpost has integrated elastomer inserts that help dissipate road chatter and vibration, without sacrificing responsiveness or power transfer.
