Which team has won tour de France most?

Answer 1

Teams are only who is sponsoring the team at that time, its very hard to quantify what constitutes the same team when team members change, key members leave, the team changes names. A good example is Lance Armstrongs team...originally USPS, then changed to Discovery and then without Lance became Astana! so is that the same 'team'?

a better question is which rider won the tour the most: Lance Armstrong 7 times and the team then was USPS/Discovery so does that answer the question?
