Roberto Visentini (born 2 June 1957) is an Italian former professional road racing cyclist.
Visentini was born in Gardone Riviera, in the province of Brescia, and had a brilliant junior career. In 1975, he was both Junior Italian champion and World Champion. As an amateur he won the 1977 time-trial Italian Championship.
In 1986, he then won his first and sole Giro by defeating racers such as Saronni, Francesco Moser and Greg LeMond. His lead was from first stage to the end. In the 1987 he was the protagonist of one of the most controversial episodes of 1980s Italian cycle racing: Visentini, who was the racing for Carrera Jeans–Vagabond, took the pink jersey for the leader of the general classification off the shoulders of teammate Stephen Roche after winning an individual time trial. Several days later in a mountain stage he was suddenly attacked by his teammate Roche, who had contravened the team's order. The Carrera team led the peloton in the chase after Roche until Visentini was left without any teammates. Visentini riskily tried to recover the gap alone but finished several minutes behind Roche who took back the pink jersey. Several days later Visentini fell and had to retire from the race.
Roche left the Carrera team which kept Visentini, but he was no more able to repeat himself at the former levels. He concluded his career in 1990 with 18 victories, including the 1981 Giro del Trentino and the 1983 Tirreno–Adriatico.false
