With seven wins at Paris-Roubaix, our Roubaix has proven that Smoother is Faster. Until this moment, however, smooth has admittedly come with some compromises. But not anymore. The all-new Roubaix Comp now delivers compliance without compromise by introducing a radical new Future Shock 1.5 that gives you more control on rough roads, a new Pave seatpost that creates our most balanced Roubaix to date, aerodynamics that equal the Tarmac, and a Rider-First Engineered frame that's shed some serious weight. Is it still comfortable? Sure, but don't call it a comfort bike, because performance was behind every engineering decision we made. This is the new Roubaix.

For the build, we spec’d the Expert with Shimano Ultegra Di2 for its powerful hydraulic disc brakes and super crisp 11-speed shifting. Of course, you’ll be rolling on sturdy wheels courtesy of a DT R470 Disc wheelset.

- The new frame delivers compliance without compromise via the perfect balance of aerodynamics, light overall weight via a FACT 10r carbon construction, compliance, and Rider-First Engineering. With tube shapes that were born in our FreeFoil Shape Library and validated in the Win Tunnel, the new Roubaix is more aero than the Tarmac SL6. Meanwhile, to ensure the weight and ride quality, we turned to a Rider-First Engineered design to deliver optimal stiffness and compliance across all sizes, from 44 to 64cm. Of course, the frame has shed some serious weight in the process. And to prep you for your own Hell of the North, we've made room for 33mm tires.

- To go along with the new frame, we've also developed a totally-new S-Works Pave seatpost. Not only is it the first compliant seatpost that's ALSO aerodynamic, it does so without any additional weight or finicky contraptions. Starting with the same D-shape design found on the Tarmac, we took its compliance a step further by building additional flex into the upper and developing a new drop-clamp design in the frame. This provides plenty of compliance while staying perfectly balanced with the front-end, so you get a smooth, balanced ride no matter how rough the road.

- With 20mm of rough-road-taming travel, the Future Shock 1.5 not only delivers a smoother, more comfortable ride, but it also reduces fatigue and increases speed over harsh terrain. The new Smooth Boot, meanwhile, enhances the aesthetics to bring a clean transition from the head tube to the stem

Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:

Shifting Performance
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.

Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.

Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
