Giovanni Bramucci was an Italian road cyclist, especially well suited to the team time trial. Bramucci was named to the Italian team at age 20. In 1967 he won the road race at the Mexico City pre-Olympic test. At the 1968 Mexico City Olympics he helped Italy to a bronze medal in the team time trial, which was somewhat disappointing as they were favored. A few days later he placed eighth in the individual road race.
Within the month Bramucci won another bronze medal in the team time trial at the World Championships in Uruguay. At that meet he placed 10th in the individual road race. Bramucci turned professional in 1969 with Griss but moved to Germanvox Vega in 1970. He had little success as a pro, with his only major win being stage 11 at the 1970 Vuelta a España from Zaragoza to Catalayud. He rode the Giro d’Italia in 1969 and 1970 but did not finish either time. He also rode Milano-Sanremo both years, placing 92nd in 1969 and 60th in 1970. At the end of 1970, without a contract, he left competitive cycling.
