Smoother is faster when it comes to the Roubaix SL4 Expert. With the engineered compliance and responsiveness of its SL4 FACT 10r carbon frame and fork, along with the legendary performance of the mechanical Shimano Ultegra build kit, it's a bike that will ensure you stay fresher, longer—no matter how long your ride may be.
  • High-modulus SL4 FACT 10r carbon frame with tapered head tube and compact race design provides incredible responsiveness, while the engineered compliance and Zertz inserts smooth out vibrations and road chatter.
  • 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.
  • The incredibly smooth-running Fulcrum Racing S-19 Light wheels will help transfer your power to the road. They're with butted alloy spokes to be tough enough to handle even the roughest roads and still come back for more.
