    Roubaix

    2021 Roubaix

    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 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 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.

    This Roubaix provides a tremendous value, but like the frame itself, this value doesn’t come with any compromises. We spec’d it with Shimano’s Tiagra 10-speed group for its crisp shifts and powerful hydraulic disc brakes, as well as reliable Axis Elite Disc wheels, a Praxis Alba crankset, the all-new S-Works Pavé seatpost, 28mm Espoir Sport tires, and our fan-favorite Power Sport saddle.
