Controversial champion Alberto Contador was given a hostile reception by some of the crowd at the official Tour de France presentation.
Contador is bidding for a fourth yellow jersey but is competing under a cloud following a positive test for clenbuterol at last year's race.
He has been cleared by the Spanish authorities, although the Court of Arbitration for Sport is set to make a final ruling in August on whether he was to blame for a positive test he blamed on contaminated meat.
Around 7,000 people turned up at the Puy-du-Fou to watch the 22-team presentation two days before the race start.
New Zealand's sole representative on the Tour, Julian Dean, has no concerns about Contador competing despite a drugs controversy hanging over him.
36-year-old Dean is hoping for a good Tour despite an average year so far as he's off contract at the end of the season and wants to extend his career for at least another year.
