There seems a really easy eay to eradicate this problem, have the same system as current with 4 riders but in reality you have a squad of 5 or 6 day there on the day. You can make as many changes as you like as long as a rider does not have more than 5 rides as current (plus tactical sub). Then there will be no fake injuries as people can change when they want and it will be thecountry with the best squad/team that actually wins the thing. Makes filling a programme more difficult but best team on the day wins and adds more excitement and puts more of an onus on the team manager also. Most teams had some of their squard riders there anyway Howarth, Hans etc. Only problem is someone like Russia but if they can't get a team of 4 riders they probably don't deserve to win the world cup anyway.
