As this thread was mentioned in
my thread, I thought I'd chime in. Nationalism, no. Politics, a little bit I suppose: I'd prefer not to buy from countries that are communist (China). Cultural, yes: I like the French and French bikes.
Mostly though, I gravitate toward bikes that are C&V, my size, and made with Reynolds 531, regardless of country of origin. Decent fork rake is often a determining factor. Not as picky about components, but I really like Suntour stuff and friction shifting.
Having said this, my next bike will probably be an American-made custom (specifically Oregon) or an Alex Singer. Tentatively planning a trip to France during the Tour in 2022.
