Team Sky have reiterated their zero-tolerance stance to doping after the United States Anti-Doping Agency report which has rocked cycling.
The British team, home of Tour de France winner Bradley Wiggins, will ask every rider and member of staff to sign a statement to confirm they have never been involved in doping.
A statement read: "There is no place in Team Sky for those with an involvement in doping, whether past or present. This applies to management, support staff and riders.
"Over the coming weeks, we will talk individually with each team member and ask everyone, at every level of the team, to sign up to a clear written policy, confirming that they have no past or present involvement in doping.
"Should anyone choose not to sign up to our clear policy they will have to leave the team, as will anyone who does sign but is subsequently found to be in breach."
Canadian rider Michael Barry was one of 11 riders who testified against Lance Armstrong to the USADA, who have accused the United States Postal Service team of running "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
Barry spent three seasons with Team Sky before retiring last month after admitting to doping earlier in his career.
Team Sky sports director Sean Yates worked with Armstrong at the Motorola and Astana teams, but has denied any knowledge of doping.
Australian Michael Rogers, a key member of the Tour-winning team, worked with disgraced doctor Michele Ferrari, implicated in the USADA report, earlier in his career but also denies using performance-enhancing drugs.
Armstrong did not co-operate with the USADA investigation and maintains his innocence.
Team Sky principal Dave Brailsford informed his charges of the policy on the first day of the end-of-season camp.
"We are a clean team and have shown it is possible to win clean," the statement added.
"We want a team in which riders are free of the risks of doping and in which fans - new and old - can believe without any doubt or hesitation.
"There is no place in Team Sky for those with an involvement in doping, whether past or present. This applies to management, support staff and riders.
"Like others, we have been shocked by recent revelations of systemic doping in cycling's past. So we have taken steps to reaffirm our commitment to being a clean team.
"We are making this statement because we believe it is important to be open about the steps we are taking. However, we do not intend to give a running commentary on this or to discuss any individual at this time.
"By reaffirming Team Sky's position on doping, we aim to play our part in a clean future for cycling in which everyone can have confidence in the sport."
Brailsford insists he is committed to the zero-tolerance stance.
He said: "A lot have said that in the 1990s and early 2000s every rider could have doped.
"It's highly likely, from what we've learned recently. But it doesn't change
my belief or my commitment to run a clean team with the same policy.
"If someone has a (doping) past, and they're lying, the likelihood of it
coming out is high.
"The truth is going to come out, and it could be painful for us. If we have to start from square one, so be it.''
