Specialized Roubaix SL4 Sport 105 (2014)

When called to arms, the classic-winning Roubaix reacts as though simply an extension of mind and body. Pros like Tom Boonen—who rode his Roubaix SL4 to a record equaling 4th Paris-Roubaix victory in 2012—count on its smooth ride and responsive handling to get the job done. With size-specific engineering and a frame that delivers the best balance of vertical compliance, low weight, and torsional stiffness, riders of all sizes can experience the same ride quality and performance as Boonen.

Smoother is faster. The more comfortable and less fatigued you are at the end of a 4 hour ride, the stronger you'll be. Like shocks on a race car, the Zertz vibration damping inserts on the Roubaix SL4 help absorb road impact and keep power planted firmly on the road - couple that with a FACT carbon 8r frame and it's still plenty stiff to thrash around in a sprint. Just ask four time Paris-Roubaix champion Tom Boonen.
