it kinda gets tough with companies. the "big three" will make some of the highest models in house but still have other models shipped overseas, so i would be more specific and go by models of bike. but with a company like TIME, all bikes, including entry level are hand made in france. i think cervelo is putting out one of the most high end bikes out right now in the project california, everything is done in house by hand, they are not afraid to show the videos of the process and it's a very beautiful thing, very high quality, and the cost reflects that.
