Cool bike, reminiscent of my 1960 Capo Sieger, with its one-piece steel Agrati cranks, aluminum Simplex rings, half-step gearing, and Campag. Gran Sport derailleurs. Do you know what your frame tubing composition is? If you have a 27.2mm seat post, you probably have double butted Reynolds 531, at least on the main triangle. Chrome is expensive, and since chrome does not hold up well where I live, about a km downwind of the Pacific Ocean, I went for a full paint job on my 1959 Capo Modell Campagnolo.
