For some of us wheel building is a science in itself, it is a question of conviction for others. It is widely recognized, that professional craftsmanship is superior to machines: a worker will check material and process steps with all senses. He will work carefully with sensitive finishes and do the necessary.
A durable wheel is made out of good material, equally high spoke tension and careful distressing of the spokes. Spoke breaks are very rare and normally there is no need of truing the wheel again.
