The frame is made from Specialized’s proprietary FACT 11r carbon fiber, which provides unparalleled stiffness and strength while minimizing weight.

Aerodynamics Redefined: Wind Tunnel Testing

To develop the Roubaix Expert, Specialized subjected their design to extensive wind tunnel testing. This process allowed them to refine every detail, from the shape of the frame to the position of the wheels, in order to minimize air resistance and maximize speed. The result is a bike that not only looks fast but also performs at an elite level.
