I think you want to be careful with the term. The bias is clearly based on culture, not race. No major American presence in Soccer. We're not barred from the sport. Interest in it is just not culturally pervasive here. If half of Kenya jumped on bikes today, I would expect that we would see an explosion of pro Kenyan cyclists within a year or two. For Kenya, it might be a matter of infrastructure. Pro road cyclists tend to stick to paved roads. Fewer than 8% of Kenyan roads are paved. That's ~11,000 kilometers out of ~161,000. Cycling isn't a sport of colors, it's simply a first world sport.
