It seems unless you are a French, Spanish or Italian rider then you don't deserve to win the TDF.
I don't think it is a nationalist feeling that opposes the Anglophones. The thing that cycling traditionalists can't stand is the way Western technology and science has changed the training, preparation and recovery programmes. Riders no longer are separately purely by ability.
It's comparable to the reason why traditional rugby union fans disparage rugby league, because professionalism has meant that RU teams have recruited and adopted RL coaching, training and playing practices. Essentially, since then, the opportunities for the flair player in a given RU match have diminished ... just as they have in a given post-Superleague RL match.
In cycling and rugby, you can't halt progress. However, it is natural for we fans to revere the old-style characters that graced our sport.
