I do not know much about this question, the only thing I have heard is that commentator on Eurosport mentioned a few times that UCI points one rider obtains are counted for the team which signed him for the next seasons.
So I wondered what are the criteria based on which a team gets WT license for the next season? Is there some minimal number of points they must have? Are there some conditions about the budget? Are there some other conditions a team must fulfill?
