A couple of modern suggestions I hope will be forgiven..
Firefly make some exceptionally well finished machines with real beauty in the details. The design and execution of their anodized titanium graphics is stunning.
Framework Bikes in Ontario are also producing beautiful, non traditional frames. CNC'd lugs bonded to carbon tubes, all produced in house.
Bonded lug bikes are obviously not new, but their approach is one of ever evolving development. As far as I can see Framework is a very small operation that leverages their knowledge and skill with these industrial production techniques to produce bikes that have a true artisan feel. It will be amazing to watch where they go in future.
