No doubt it needs shortening for cyclings sake. Two major 3 week races Is enough. I think every year there should be two groups of riders that race one giro say nibali Quintana aru and then Contador froome valverde do tour. Then at two week vuelta have match inbetween giro and vuelta with say nibali Quintana aru one team valverde froome Contador another. It could be champions of champions if you want bit like NBA. Cycling needs this to improve sponsorship and money
Just no. I'm open for any improvement for cycling but this is just the exact opposite. There are numerous points why I don't like this idea, and just to name a few:
1.) Only because they are officially in one team, why should Nibali, Quintana and Aru work together when they get paid by different people.
2.) Stage races consist of gc relevant stages but also flat stages and stages for the break. Thats what makes cycling cyling but it would be completely gone in your Vuelta
3.) Who qualifies to be in the all star teams? You can't just rely on old results because that way young and talented riders will never get a chance
4.) A gc rider can never try the double
5.) If you abandon (for example due to a crash) you can't just ride another gt instead
6.) As Libertine Seguros has already said it, the riders who don't have the giro in their legs when they ride the vuelta have a huge advantage. Moreover they will have a disadvantage in the more important tdf, why they will probably just skip the vuelta which automatically leads to point 7
7.) Nobody will ride the giro.
8.) Nobody will ride the giro except you meant that the riders can't choose which gt they want to ride which would be even worse
9.) Just imagine there are no spanish guys in the all star team. That would be horrible for the vuelta.
10.) This would completely mess up the whole traditional calendar.
This is already more than enough reason to not carry your plan into effect and I'm very sure I still forgot many important points.
