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 S-Works Roubaix SL4 help absorb road impact and keep power planted firmly on the road—couple that with a FACT carbon 11r frame and it’s still plenty stiff to thrash around in a sprint. Just ask 2014 Paris-Roubaix champion Niki Terpstra.
