1972-ish Atala Competezione, royal blue and white, 531 plain gauge main triangle, sewups- it might still be the most beautiful piece of machinery I've ever seen. I saw it hanging in an Ann Arbor bike store when I bought my hi-ten steel, QR wheel basic 10 speed in '72 or '73. I bought a used Competezione in Rockville, MD in 1980, put clincher rims on the hubs, and replaced the Campy Valentiono/Gran Turismo derailleurs with Suntour. Stolen Labor Day, 1981.
