Dopers should not be allowed to play a part in cycling's future, Olympic cycling hero Chris Hoy has said.
In the wake of Armstrong's confessions and speculation that he is trying to engineer a return to the sport, the Edinburgh six-time Olympic track cycling gold medallist said.
"We must break the chain of the past to the future and not include people who have been involved with that," Hoy told BBC Radio 5 live.
"It is a tough thing but the sport is trying all it can to reform and change - and to make the future better.
"It's all about how we can work to stop this sort of thing happening again in the future," said Hoy.
"The way we stop that is show that you can do it clean - you look at Bradley Wiggins in the Tour - and increase the testing as they are doing now: the whereabouts scheme, where you have to be available every day for testing, and tell the testers where you are.
"You could be tested on Christmas Day, you could be tested anywhere at all, they could come randomly - these blood and urine tests weren't around to the extent that they are now in the early 2000s when Lance was winning the Tour.
"The Tour de France is a different kettle of fish to what I do, but it doesn't matter what you do - if you're on two wheels you do the best you can and do it clean."
Hoy said that he felt he had been let down by the dopers, whose confessions had led to his own successes coming under scrutiny.
"It is frustrating when you're a cyclist and your sport is brought into disrepute and people ask questions of you and your branch of the sport," he said.
"But you have to accept that and you realise all we can do as cyclists is go out there and compete clean, try to win and try to show the next generation of cyclists you can do it clean," said Hoy.
