The author Jobst Brandt will go down in history for writing his opus - The Bicycle Wheel. The no-fluff read gives actual engineering data to support his contentions about bicycle wheels, materials and construction. Although a bit dated, it yields timeless techniques and instruction for the first time wheel builder and acts as a reference for the more experience hand. It will also guide you on how to maintain wheels that are already built.
Probably the best book ever written on wheel building and theory. Everything you need to know about the technology behind the bicycle wheel in 150 pages.
