Rabobank

Rabobank began it's team sponsorship back in 1996.  Now, in their fourteenth year, they are among the longest running sponsors in the sport and the longest among ProTour teams.

If you were to believe Cyclingnews.com's caption writers, Rabobank has planned their team well into the future.

It is good to know Rabobank will still be around in 2020.  I am not sure that these guys will still be competitive at that point, however.
