Castelli Sanremo BTW Speed Suit
Over a decade of development on the roads of the WorldTour and in the wind tunnel.
This is the suit that started a revolution. Before the San Remo Speedsuit made its debut in 2011 at Paris-Roubaix, the thought of wearing a speed suit for anything but a time trial seemed insane. But after it achieved victory in its first outing, the way cyclists dressed for racing changed forever. In its latest evolution, the San Remo BTW Speed Suit is even faster. On top we use our new redesigned Aero 7 Jersey, which is paired with the reduced-seam bottoms from our Body Paint 4.X speedsuit, a combination that is slippery against the wind. As always, the suit opens completely in the front for added ventilation and easier nature breaks and has three pockets on the back for storage. We've also used our Progetto X2 Air seat pad for comfort during the toughest rides or races. For extra aerodynamic gains, pair this suit with our Bolero SS base layer. Extensive hours in the wind tunnel have shown this combination to be the fastest yet.
