I think the issue, as Robert noted, is "price point" for a stock bike and, at least to me, remains a good reason to start from a frameset if it's in your budget. There are still some excellent parts manufactures with long lasting repairable parts. White Industries, Phil Wood, Cane Creek, DaVinci, TA Specialties, even Shimano etc. Yes, you pay a premium up front for some but they last and last and can be maintained and rebuilt if needed. I have three pairs of custom built wheels on White Industries hubs, one being over 20 years old, that has never needed anything but the infrequent grease replacement or pawl lube. Though, none of this is aided by the bike industry and it's constant changing of part standards.
