the 1947 giro d'italia was the first giro to have all competing riders be a part of a trade team, rather than some riders competing as independents. fausto coppi, gino bartali, and aldo ronconi broke away during the fourth leg while climbing the abetone and rode into prato where coppi won the stage and bartali took the overall lead. bartali held that lead until the sixteenth stage when his chain dropped on the climb of the falzarego when coppi saw this he attacked. on the descent of the falzarego, the same misfortune struck coppi, which allowed bartali to rejoin him. later, coppi attacked on the passo pordoi and bartali could not keep up. coppi took the stage and the overall lead, which he held all the way to race's finish. fiorenzo magni won the 1948 giro d'italia by a margin of eleven seconds — the smallest margin of victory in the history of the race — over ezio cecchi. magni gained significant time after being a part of a successful breakaway in the race's ninth day of racing. magni's lead over race favorites coppi and bartali was near thirteen minutes. cecchi briefly gained the lead of the race for two stages; however, magni took the lead after the seventeenth stage which saw riders cross the pordoi pass. coppi and his team suspected that magni received help from the spectators, which the organizers gave magni a two-minute penalty for. the penalty to magni wasn't enough to prevent him from winning the race, but he did so by the slimmest of margins.
