Guimard's personality led to disagreements with riders, notably with Hinault in the mid-1980s. Hinault did not enter the 1983 Tour de France due to a knee injury, and his teammate, Laurent Fignon, won the race. The following season Hinault left Guimard to ride for the new La Vie Claire team. Guimard had the previous year taken on a young American, Greg LeMond, whom he knew from his win in the world junior championship in 1979 and whose career he had followed. Negotiating a contract reported as setting new standards for what riders could expect to earn exhausted his fax machine, Guimard said. "Americans are the kings of paperwork."
