What I wrote is not from my head, I am not that much die hard pro biking scene follower. That was the view taken by the TV commentators of the major pro races that caught my interest at the time. I am aware of all those names and teams you mention and of course the TV commentators too. I think it had to do with Germany not having their own big race(s) and popular home base for cycling and it being way richer economically than other EU countries. Like no one expects anything from its small neighboring countries, Czechs and Slovaks, whose talents have to leave and find place on some other countries, teams, sponsors (Sagan, Kreuziger, Stybar).
Prague also might host opening TDF stage one day like Germany did several times in past but that is about as far as it may go.

That the thread like this one was made in the first place is indicative of the general perception and it wouldn't exist if things were 'ALL RIGHT' in this direction as your reply would seem to indicate. When you say Italy, you can say in second breath Campagnolo bikes, Ferrari cars, when you say Germany, you can say Mercedes but you can't cite an iconic bike manufacture. And that is what this is about.
