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.

Specialized Roubaix SL4 Double

The Specialized Roubaix is celebrated for its exceptional comfort and innovative features, such as the Future Shock suspension system and CG-R seatpost, which provide a smooth ride over rough surfaces. It's noted for its light frame and race-worthy efficiency, though some find its aesthetics and initial suspension feel unconventional. Comparisons often highlight its competition with the Trek Domane and Specialized Tarmac.
