OP you can't just waltz in here asking the important questions like that. Spandexfags don't want to be faced with the harsh reality that the entire bike industry is a soulless corporate black hole just like everything else.
And don't even begin to even think about things like "for the price, how come motorcycle chains, bearings and brakes last for tens of thousands of kilometers more even though they are subject to unfathomably more extreme forces than bicycle parts?" or "how come you can buy a new small displacement motorcycle for the same price or even less than a bicycle?"
