This Bikeradar article raises a very good question. I hope you feel it interesting as well.
For me, I really don't care where it's produced, but how it's produced in the exact manufactury. As an industry person, I know Giant is assembling Trek, Merida assembling Specialized, some Rapha produced in China. Our OEM factory is also producing Cervelo, though I can't name which factory. Cost is the reason, but the quality is the premise.
However, as a consumer, I really like to have a bike made in Europe, simply because of the time-honored cycling culture. After 11 years of riding, partly because I'm growing, I'm less enthused with the equipment, but more with cycling itself and the cycling culture. Europe has the longest cycling culture and the highly engaged mass base. I own an Orbea Orca, and I would like to have a Condor from U.K.
No doubt, there's an unprecedented centralization of bike manufacturing industry in East Asia, or simply Mainland China and Taiwan. It causes several results like complete branded bikes take the lead in the market, while custom-build bikes get undesired. Why? It significantly lowers down the cost. You pay less and get a decent bike if you buy in a brand bike store. If you produce bike parts and want to succeed in OEM market, you have to stay close to China Mainland and Taiwan. That's also part of the reason why we think SpeedX could succeed. We have the supply chain advantage. We're geographically close to all the vendors in Mainland China and Taiwan and share the same culture. It could bring us lower cost and faster supply chain response. A good example is that FSA co-engineers with SpeedX on the T47 bottom bracket and the stemless handlebar of Leopard 2018.
There's a heated discussion in the comment area under that Bikeradar article. Let me know your thought on this topic.
