Sir Dave Brailsford has hit back at those who doubt Team Sky's clean approach to the sport.
The outfit's dominance in road cycling in the last year has resulted in some within the sport speculating on whether the results are possible without use of performance-enhancing substances.
The Team Sky principal told Cyclingnews.com: "If I'm a doper, if I'm a liar, I'm a liar in my personality through and through. So why didn't I dope the Olympic team for the last 15 years? Have I just decided I'm going to do it with this team? I'm not going to do it over there but I'll cheat here? Full gas.
"But we've dominated the Olympic games for 15 years. Explain that to me. We didn't just win at the Olympic Games, we dominated them, we smashed it out of the park. More than anyone else has ever done. That level of performance is monumental.
"If I'm a liar and a cheat and if my ethics and morals are all about cheating, if that's what we're doing here, lying to the world and cheating, then surely I'll be doing it in other places in my life. Not just parts."
Brailsford received his knighthood last month for his achievements with Team Sky and British Cycling.
