Body Castelli Soudal Quick-Step 2024 Sanremo BTW Speed Suit. This is the bodysuit that started a revolution. Before the Sanremo Speed Suit made its debut in 2011 at Paris-Roubaix, the thought of wearing a speed suit for anything other than a time trial seemed crazy. But after it crossed the finish line in its first public outing, what cyclists wear for racing changed forever. In its latest evolution, the Sanremo BTW Speed Suit is even faster. On top we use the newly redesigned Aero 7 Jersey, which is paired with the Body Paint 4.X speedsuit's reduced-seam pants, a combination that prevents the fabric from slipping in windy conditions. As always, the bodysuit opens fully at the front for increased ventilation and to facilitate physiological breaks in addition to having three pockets at the back for storage. We also used our Project X2 Air pad for maximum comfort during challenging rides or races. To further improve aerodynamics, pair this bodysuit with our Bolero SS baselayer. Long hours in the wind tunnel proved that this combination is the fastest ever.
