ROUBAIX SL4 DISC
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. AXIS 2.0 Disc wheelset is lightweight with strong, reliable rims Espoir Elite 25c tires w/ BlackBelt protection for a smooth, fast, and confident ride Shimano Sora compact crankset for lightweight, wide-range gearing Tektro Spyre, mechanical disc brakes for excellent, all-conditions braking performance Shimano Sora rear derailleur ensures you never miss a critical shift Ultra-light Body Geometry Toupé Sport saddle conforms to your body for optimum fit Lightweight and efficient, FACT carbon CG-R seatpost w/ Zertz vibration damping

ZERTZ
WHAT Viscoelastic dampers integrated into the Roubaix seatstays and fork.
WHY Absorb road vibration to minimize fatigue and provide a more comfortable ride.
HOW Vibrations travel from the road through the wheels and up through the frame and fork. Putting dampers at the mid-section of each seatstay and fork leg helps dissipate these vibrations before they reach the rider's hands and body.
SHAPED SEATSTAYS AND CG-R SEATPOST
WHAT Engineered seatstays (all-frames) and our newly designed CG-R seatpost (S-Works, Pro, & Expert) work to sharpen handling and damp road vibration.
WHY Seatstay shaping with molded Zertz increases rear-end compliance and mutes vibration, while the CG-R further enhances compliance over rough surfaces, minimizing rider fatigue.
HOW Redesigned, more triangulated seatstays have straighter lines from seat tube to dropout. This better engineered structure increases lateral stiffness while maintaining vertical compliance. The unique CG-R design works to suspend the rider from bumps to create a smoother, more compliant ride.
SIZE-SPECIFIC ENGINEERING: FORK
WHAT More compliant and lighter fork with size-specific crown sizes (1-1/8”, 1-1/4” and 1-3/8”).
WHY Creates a more balanced and stable ride for riders of different sizes.
HOW Better layup and size-specific bearings means the fork is 20% more compliant and 30g lighter overall.
HYPERBOLIC SHAPED HEAD TUBE
WHAT Strategic surface shaping of the headtube/ toptube/ downtube junction, designed to optimize specific ride characteristics.
WHY mproves torsional stiffness by creating a more direct connection to the front wheel through the steer tube, while maintaining compliance.
HOW By manipulating the geometry of this junction, we make gains in stiffness without having to use an overly stiff fiber that would sacrifice vertical compliance. Widening the toptube and downtube eliminates flat spots behind the headtube for greater frame stiffness.
SIZE-SPECIFIC ENGINEERING: FRAME
WHAT Size-optimized frame engineering.
WHY To ensure riders of all sizes experience the same sharp, smooth handling attributes and enjoy the ride quality and performance Roubaix is known for.
HOW Size-specific tube diameters, seatstay angles, and carbon fiber layup change as you go up in frame size.

I have been riding Specialized bikes for the past 3 years and there is undoubtedly no going back. I have never found a product that delivers on this level every time. Looks fast feels great. Congratulations to specialized...you did it again.

Yes, I recommend this product.
