From the manufacturer:
The legend, racing for more than 40 years, will all the technological updates. Microcast Cinelli "Spoiler" bottom bracket. Original fastback seat stay designed by Cino Cinelli. Columbus top-range steel enriched with Niobium and drawn in traditional diameters. Jewelry-finish chromium-plated logs with artisan attention to detail.
A modern steel classic and always at the top of the range. For true connoisseurs of traditional diamond frame with horizontal top tube. While many claim roots to cycling's storied past, the Supercorsa stays true to itself. Made in Italy in 17 sizes and 8 colorways.
