DX,
That is one part of cycling the East Africans may have a problem with. Not only does cycling require aerobic capability, but also alot of strength, especially when dragging your bike up large hills. So, that was kind of what I was wondering in the beginning as to whether or not they may be able to be a very competitive force in Pro cycling in the near future, as those nations slowly emerge from third world status.
I think as caucasians, the physical makeup may just be the right balance of physical frame size, muscle mass, and cardio-vascular capability to allow caucasians to essentially provide the very few that can excel well beyond the norms of what other ethnic backgrounds can provide.
The money issue is also one that I raised earlier. To set up a Pro team takes some pretty pennies, and even most mid-sized American companies don't like to flip the bill for such a heavy expense in a sport that does not have the popularity of other major sports.
I guess, all we can do, is just wait and see.
