Very exclusive. Totally original, 1982 catalog. The Motobecane Profil 2, a pioneer of aerodynamic bicycle frames from the 80s, like Bernard Hinault's Gitane time trial bike. Wind tunnel tested, a bicycle designed for low wind resistance and efficient air penetration at high speeds, which it achieved through the use of Aero 1020 steel teardrop-section tubing, Shimano Adamas AX components, and Huret derailleurs.
