About the BikeWith six wins at Paris-Roubaix, the Roubaix has proven that Smoother is Faster. Until thismoment, however, smooth has admittedly come with some compromises. But not anymore.The all-new Roubaix Expert now delivers compliance without compromise by introducing aradical new Future Shock 1.5 that gives you more control on rough roads, a new Pavéseatpost that creates our most balanced Roubaix to date, aerodynamics that equal theTarmac, and a Rider-First Engineered™ frame that’s shed some serious weight. Is it stillcomfortable? Sure, but don’t call it a comfort bike, because performance was behind everyengineering decision Specialized made. This is the new Roubaix.The new frame delivers compliance without compromise via the perfect balance ofaerodynamics, light overall weight via a FACT 10r carbon construction, compliance, andRider-First Engineering™. With tube shapes that were born in our FreeFoil Shape Libraryand validated in the Win Tunnel, the new Roubaix’s as aero as 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. Ofcourse, the frame has shed some serious weight in the process. To prep you for yourown Hell of the North, Specialized have made room for 33mm tires.The 105 groupset featured on this model is well suited to long days in the saddle and riding the year round in all conditions. Freshly updated by Shimano at the end of 2018 the groupset utilizes the improved ergonomics and most of the recent technological advancements of Dura Ace and Ultegra. Hydraulic flat mount brakes serve up plenty of well-modulated power so that slowing down is always safe and predictable. The DT Swiss wheelset completes the lightweight, durable specification to deliver a bike that rides as fast and as smooth as it looks.
