Specialized Roubaix SL4 Pro Disc Race UDi2 Carbon Road Bike 2016

With its extremely responsive and stiff SL4 FACT 10r carbon frame and fork, coupled with our Zertz inserts, road vibration and chatter are all but eliminated.

Add to that the incredible and hassle-free performance of the Shimano UDi2 11-speed electronic drivetrain and the Roubaix SL4 Pro Disc Race UDi2 is a race-ready weapon just itching to be put through the paces.

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.

Roval Rapide CL 40 Disc wheels are the ultimate balance of light weight and aerodynamic. Capable of rapid accelerations and designed for the demands of disc brakes, the Rapide CL 40 wheels are a huge performance upgrade to any bike.
