Team Sky principal Sir Dave Brailsford believes the spitting, booing and physical intimidation to which his riders have been subjected at this Tour de France is a phenomenon particular to "French culture", adding that unless French fans start to "respect top international teams" they may find they do not come any more.
Speaking on the Tour's final rest day on Monday ahead of the first of five Pyrenean stages which will decide the race, Brailsford said the treatment being meted out to his team was unacceptable.
"I don't think it's going to stop," he said. "I'm not too optimistic on that front. We're trying to remain dignified, we're trying not to react and we're trying not to get distracted by it. But I don't think spitting and throwing things has a place in professional sport.
"I'm not sure it's got a place in everyday life but it seems to be the thing that's done here. It's a shame but we're not going to let it distract us."
Team Sky - who have dominated the Tour in recent years while at the same time finding themselves at the centre of a number of controversies - are unpopular with swathes of cycling fans, particularly in France. One fan was arrested on Alpe d'Huez last Thursday for allegedly punching Chris Froome, while another pushed him as he rode past.
