We in the U.S., and especially at BF, are pampered by the availability of high-quality bikes and components. In developing countries, people are happy to ride whatever bikes they can get their hands on. I have a cycling buddy who moved to Uganda for mission work, and he sent me a photo of his "especially good" bike that a local helped him find and buy. It's good because it's extra strong: reinforced with re-bar, so super heavy. The brake pads are made of car tires. Anyone here on BF would be embarrassed to be seen on it.
