That's the definition that works best for me. I don't care so much about whether or not *I* specify the design or the dimensions or the angle or the components; I'd be just as happy to defer most of those decisions to the builder (presuming of course that the builder understands my wants, needs, intended uses, riding style etc). To me a "custom" bike is when the builder goes into his shop in the morning and says to himself "Today I will work on Bob Ross' bike" and every decision he makes about the work he does on that bike is based on what he knows about *me*.
