The 2014 Specialized Roubaix SL4 Expert Ultegra Di2 Delivers The Way Only Specialized Can
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 10r frame and it's still plenty stiff to thrash around in a sprint.
— Specialized SL4 FACT 10r disc frame with Zertz is fast and smooth, with incredible light weight, size-specific engineering, and tapered headtube; FACT carbon fork with Zertz has size-specific engineering to create a more balanced and stable ride for riders of different sizes
—Specialized Roubaix Pro 23/25c is fast like a competitive tire, but features unique casing technologies for added comfort and puncture protection
—New Shimano hydraulic disc brakes provide the precise performance Shimano is known for, paired with Shimano Di2 STI shifters, renowned for their race-ready performance and exceptionally consistent shifting in all conditions
—Romin Expert Gel saddle, with hollow Ti rails, delivers the same ergonomically designed, scientifically-proven Body Geometry features that allow riders to deliver power in high-performance positions
—The revolutionary CG-R post features 18mm of vertical compliance and Zertz vibration damping, while FACT carbon construction delivers unsurpassed comfort, control, and efficiency without adding weight or complication to the frame
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.
HYPERBOLIC SHAPED HEAD TUBE
WHAT Strategic surface shaping of the headtube/ toptube/ downtube junction, designed to optimize specific ride characteristics.
WHY Improves 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: 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.
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.
WHAT Visoelastic 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.
