Tour de France champion Bradley Wiggins is frustrated the present generation of riders have been left to answer questions about the state of cycling in the wake of the Lance Armstrong affair.

The UCI, cycling's world governing body, on Monday ratified the sanctions recommended by the United States Anti-Doping Agency, who concluded Armstrong and his United States Postal Service team ran ''the most sophisticated, professionalised and successful doping programme that sport has ever seen''.

The 41-year-old was stripped of his seven Tour titles, won between 1999 and 2005, and banned for life.

Speaking at the launch of the 2013 Tour, the 100th edition of cycling's most prestigious race which takes place next summer, Wiggins said: ''I think there is a lot of anger from most people within the sport, it is a sport I love and have always loved.

''It is a shame that cycling is being dragged through this again really, not a shame that he has been caught - when you get older you start to realise Father Christmas doesn't exist and it is the same with Lance.

''But it is a shame that us riders here now, we are the one picking the pieces up and having to convince people.''

Team Sky's Wiggins, who became the Tour's first British winner in July, does not feel the latest doping revelation to hit cycling will detract from his own success.

''It doesn't take away from my victory, but as winner of the Tour de France you are subjected to a lot of other things, it goes beyond sport,'' he said.

''It is out there now, hopefully this sport can move forward - the route has been announced today, cycling isn't like that any more and we (the riders) are evidence of that."
