2021 Specialized Roubaix Sport

The all-new Roubaix Expert now delivers compliance without compromise by introducing a radical new Future
Shock 1.5 that gives you more control on rough roads, a new Pavé seatpost that
creates Specialized's most balanced Roubaix to date, aerodynamics that equal
the Tarmac, and a Rider-First Engineered frame that’s shed some serious
weight.

This 2021 Specialized Roubaix Sport provides a tremendous value, but like the frame itself, this value doesn’t come with any compromises. Specialized spec’d it with Shimano’s 105 11-speed groupset for its crisp shifts and powerful hydraulic disc brakes, as well as smooth and sturdy DT R470 Disc wheels, the all-new S-Works Pavé seatpost, 28mm Turbo Pro tires, and Specialized's fan-favorite Power Sport saddle.

  • 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, Specialized have made room for 33mm tires.
  • To go along with the new frame, Specialized  have also developed a totally-new S-Works Pavé seatpost. Not only is it the first compliant seatpost that’s aerodynamic, it does so without any additional weight or contraptions. Starting with the same d-shape design found in the Tarmac, they took its compliance a step further, building additional flex into the upper and developing a new drop-clamp design in the frame. In the end, it provides plenty of compliance, while staying perfectly balanced with the front end, delivering a sublime, smooth 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.
