Vibration Damping In-Zertz viscoelastic dampers in the fork and seatstays absorb vibrations from the road, so your body doesn’t have to.

It’s a big idea we’ve been pushing for a long time. The concept “Smoother is Faster” originated with our FSR suspension, but we quickly applied the same logic to the road through bikes like the Roubaix—as well as an ever-expanding range of equipment. With Roubaix’s three consecutive victories at Paris-Roubaix, our pros and enthusiasts alike continue to validate the performance benefits of a smoother ride.
Plush Stays Seatstays on our road bikes and hardtail mountain bikes are engineered for vertical compliance.
Vertical Compliance (MN/KN)
S-Works Roubaix SL3
More Control Less Fatigue Higher speeds
Thin To Win Smaller diameter posts on our road and hardtail mountain bikes increase vertical compliance.
How smooth is the Roubaix SL3? Simply put, the difference in vertical compliance between the SL3 and the Madone is comparable to running your tires at 90psi versus 120psi.
Shaped/Tapered Head Tube The Tarmac SL4’s and Roubaix’s uniquely shaped head tube/steerer assemblies taper from 1-1/8" at the top to 1-3/8" at the bottom (instead of the industry standard 1-1/2"). This improves vertical compliance for a smoother ride, but through strategic shaping we’ve also increased torsional stiffness, providing more precise steering.
