around 7-8 for me. Misses two things, time trial and steep mtf or last climb(chat, granon), And of course cobbles but we all knew that this year they won't be on the menu
1. Paris-Roubaix
2. Ronde van Vlaanderen
gap
3. Liège–Bastogne–Liège
4. Worlds
gap
5. Giro di Lombardia
6. Milan-San Remo
7. Amstel Gold Race
8. La Flèche Wallonne
Zomegnan with this route tries to make giro bigger than tour, but he can put 21 mtf and still giro would be insignificant to tour. History , tradition, legends, that's something giro doesn't have as near as tour.
