Yes, undoubtedly that there are poorly built handbuilt wheels out there. I'm still relatively new at handbuilding (only built just over 100 wheels) but I'm a strong believer in the principles of good wheel building so I'm not ready to accept that wheels will loose sufficient tension by just riding them. Maybe time will prove me wrong
but so far I'm doing OK. Two weeks ago I got my friend to come round with one of the early sets of wheels I ever built, he is a part time commuter and he has done just over 5000 miles. The spoke tension and trueness still very good so I still think he will need a new rim before he needs me re tensioning the spokes . I still take the same care and attention as I did then but I'm much faster now.
It's perfectly understandable that handmade wheels don't make sense to you, we all have different priorities when it comes to purchasing goods. Still, I never got handmade wheels before I made my own so I don't know whether I would have wanted to pay somebody to build me a set, I never thought about it. However, now I would go handbuild every time, even if for some reason I could not build my own wheels, I would happily pay somebody to do it for me. I still build wheels for CC members for £zero and only till the end of the year but I'm now only taking newly build wheels. After the new year I can happily recommend a terrific builder, friend of mine, but he only builds for people in the London area.
The thought of having to send the wheels back to another country put me off completely.
