Castelli Sanremo BTW Speed Suit

Castelli Sanremo BTW Speed Suit Castelli’s Sanremo BTW Speed Suit combines aerodynamic performance with road-ready comfort; representing over a decade of development both in WorldTour racing and in wind tunnel testing. The San Remo Speedsuit revolutionized cycling attire at its 2011 Paris-Roubaix debut; challenging the notion that speed suits were exclusive to time trials. In its latest form; the San Remo BTW Speed Suit features the redesigned Aero 7 Jersey and reduced-seam bottoms from Castelli’s Body Paint 4.X speedsuit; delivering unparalleled aerodynamic efficiency against the wind. With a front opening for ventilation and convenience; three back pockets for storage; and the Progetto X2 Air seat pad for enhanced comfort during rigorous rides or races; it’s designed to elevate your performance. For an extra aerodynamic advantage; pair it with our Bolero SS base layer; proven through extensive wind tunnel testing to be the fastest combination.
