"Amaury Sport Organisation (ASO) has announced that it is to withdraw all of its races from the UCI WorldTour from 2017....In a press release, ASO said it had registered its events on the UCI hors catégorie calendar for 2017, arguing that recent WorldTour reforms constitute a ‘closed sport system’.... Hors catégorie events cannot feature more than 70 per cent of WorldTour teams, which means a maximum of 15 for a 22-team event such as the Tour de France. As the WorldTour comprises 18 teams, moving down to hors catégorie level would mean some missing out. "
