For years, you had to choose between stiff and snappy, or compliant and comfortable for a race-bike—that is, until the Specialized S-Works Roubaix Dura-Ace Di2. Featuring a completely Rider-First Engineered frame, Future Shock technology, and a top-level build kit, the S-Works Roubaix with Shimano Dura-Ace Di2 is right at home at a local fondo, a Saturday group ride, or a cobbled road race.
The frame is constructed from top-tier FACT 11r carbon fiber. Its stiffness levels are also off the charts, and compared to the SL4 iteration of yesteryear, you'll experience a whole new, faster, and more efficient geometry. Through some engineering sorcery, however, they've managed to keep the same fit, feel, and position that they've all come to love from the SL4, and kept it consistent throughout the size- range due to their Rider-First Engineered construction.
Of course, you're probably thinking, "get on to the suspension thing up front." Specialized calls it Future Shock, and essentially, it's a piston in the head tube with 20mm of travel. Specialized developed this technology in partnership with McLaren Applied Technologies, and the result of this are a host of drastic performance improvements, namely in the vertical compliance department.
Specialized spec'd their cobble-crushing S-Works frame with the legendary performance of the Shimano Dura-Ace 9150 Di2 electronic build kit and 9170 hydraulic disc brakes, a full assortment of S-Works bits, and hand-built Roval CLX 32s with the legendary CeramicSpeed bearings and custom hubs. Add it all up, and you get a race bike at heart, with the technology to float over the roughest roads.
- Featuring Rider-First Engineered design that ensures every frame size has the same legendary responsiveness and smooth ride quality that you'd expect from a Roubaix. The S-Works FACT 11r frameset is their highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness, while the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.
- An S-Works FACT Disc fork is built from FACT carbon fiber for supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above.
- The Roval CLX 32 wheelset is the perfect balance of light weight, durability, and aerodynamics. It's stiff enough for sprinting, strong enough for abuse, and its CeramicSpeed bearings keep things silky-smooth, making CLX 32 wheels the ultimate all-rounders.
