The Frenchman called an end to his 17-year career at the end of the 2017 Tour de France and is preparing to make his debut as a pundit for French state broadcaster France Télévisions.
Voeckler rode through a troubled era in cycling as the sport failed to clean itself up in the wake of the 1998 Festina Affair. He has always denied doping himself but there were a number of cases involving his contemporaries – including Armstrong – and now, having initially been sceptical, he believes there was doping of the mechanical sort, as well as the chemical.
"At first, when I heard people talking about it, I laughed. I said to myself, 'What have they found now to damage cycling?'" Voeckler told French newspaper, Le Parisien.
"Later, seeing certain reports, I was convinced that some have taken us for fools and used a motor. Did Armstrong use it? With him, I'd no longer be shocked by anything."
