Go Team Radio Shack!

[Possegal]

Well it really is kind of "details". Garmin and Columbia aren't considered US teams, they ARE US teams, and RadioShack will be as well. Each team has a country they are actually registered in for their UCI license.

Garmin and Columbia are registered in the US. No one says Astana is a US team due to Lance, or a Spanish team due to Contador, or a Belgian team due to Bruyneel. It is a Kazakhstan* team because that is where it is registered. RadioShack, by all I've read, will be registered in the US, so it will be a US team. The nationality of the DS or the team members or any minor sponsors, will be "details".

* - though in an odd twist, the listing of teams from the Tour of California lists Luxombourg as its country, but that is the only place I have seen that and the UCI site doesn't say that

I think we can all agree though that in most cases (perhaps excluding Euskaltel) the team may have a country due to where it is registered, but the reality is a very international team. That's one of the coolest aspects of cycling to me.
