LeMond won the Tour de France three times with two of the wins coming in two years (1989 and 1990). He also won the World Championships twice.
Evans on the other hand has only won the Tour de France once in his career but he was the first Australian ever to win the prestigious event in 2011.
The Australian has been one of the main contenders for most of the Grand Tours in recent years and after finishing third in the Giro d'Italia last year he struggled to make an impact in the Tour de France which has been dominated by Team Sky over the past two years.
Evans is focusing on the Giro d'Italia this year and will not take part in the Tour de France as he looks to wear the pink jersey in Italy.
The 2011 Tour de France winner is now 37 years-old and LeMond thinks that Evans should keep cycling until he feels like he should stop, saying age isn't a huge factor.
LeMond said, according to WA today: "There have been too many examples of riders [racing] over age.
“I don’t think, scientifically, there is anything that changes … except, maybe a little with recovery. But your body gives very good feedback when it suffers. It tends to tell itself to back off a little bit.
“So long as [Evans] is motivated, there is no reason to think he is [ready to retire] … you just don’t go down that path.
“It depends [also] on who are the new riders. You think there are the same favourites, but all of a sudden two new riders come up.
"That’s how it evolves. But I think Cadel has some legs left."
Evans will take part in the Giro del Trentino in Italy before the Giro d'Italia as part of his preparation for the big event, which no Australian has ever one before.
There are three summit finishes and a 14.3 kilometre time trial during the Giro del Trentino which should show all the people in the cycling world how close to winning the Giro Evans really is.
Tejay Van Garderen will lead BMC at the Tour de France in the Australians absence.
