I'm pretty sure I have built thousands of wheels and they are pretty easy to do. But then again I am a professional and use a Var truing stand, along with doing the homework to build each one. I am currently building for a vintage bike that will get Torelli rims and Campy hubs. But the build will take about one hour per wheel and is going to b a great set of wheels. I expect them to last for a few thousand miles, and they will likely fail from road conditions and not from the build. Smiles, MH
