Is my hand fillet brazed in UK XTC frame technically better than a TIG welded made in Taiwan frame? Probably not.
Did Thorn make the right call moving production to Taiwan? Probably.
Thorn is probably not the best example anyway; they don't charge for the name but a fair price for the physical bike you ride away on. What makes a good custom bike such a pleasure to own and use is the obsessive attention given to every detail; if the details are slighted, it isn't worth having. But the main thing about Thorns is that they are made by obsessives. You can read reams of Andy Blance agonizing over the smallest detail of the frame, and every component, right out in public. You can see where he and his wife tested the details in some pretty rough places. You know what you're paying for: the maker as much as invites you to add it up, and challenges you to find that much technical advantage cheaper somewhere else.
In 2009 I analysed an extreme example of the sort we want at
https://groups.google.com/forum/#!topicsearchin/rec.bicycles.tech/WHY$20A$20WATERFORD$20BIKE$20IS$20A$20JOKEwhen I priced a Waterford frame held up to me as the ne plus ultra by American roadies hounding me for having bought a German bike, and discovered the frame alone cost more than my complete, fully fitted bike (Rohloff, SON, BUMM, Magura, Schwalbe, Brooks, the best of everything, with custom components made to suit the balloon tyres where necessary). The irony is that Waterford is the premium line of Paramount, the parent firm of Schwinn, who invented the balloon-tyred beach cruiser, of which my Utopia Kranich is a sort of hugely developed distaff cousin (it is a bike designed from the 60mm Big Apples up), whereas Schwinn are stuck in a time warp, charging huge sums for chrome plating while offering nothing but their name to justify charging five times as much as Utopia for the frame and fork. Or more than five times as much as Bob Jackson, or four times as much as Mercia, which Anto likes, and I do too. Mind you, they paint the name Waterford huuuuge on the down tube so nobody poorer than the person who bought it can miss it. I think that may be the point, your bike's expensive name as ostentatious exclusivity.
