Bicycle Wheelbuilding

Chapter 1: Why Wheelbuilding Is a Math Problem — The Promise of This Book

Every wheel is a lie told in metal. The hub and the rim are not connected by spokes — not really. They are connected by triangles, and the spokes are merely the struts that hold those triangles rigid. Once you see that, once you stop thinking of a wheel as a circle with sticks in it and start seeing it as a lattice of interlocking triangles, everything else falls into place. Spoke length, tension, lacing pattern, dish — it all becomes geometry and force, and both of those are things you can measure, calculate, and control.

This book is built on that single idea. If you can measure a hub flange and a rim, and if you can do basic arithmetic, you can build a wheel that will outlast the frame it's bolted to. Not because you have magic hands. Not because you've done it a thousand times. Because you did the math first, and the math doesn't care about your experience level.

I've been building wheels professionally for nineteen years. I've built racing wheels that cost more than a used car and touring wheels that have crossed continents twice. I've made every mistake you can make with a spoke wrench, including one that cost me a $400 carbon rim and a week of my life. The mistakes weren't due to lack of skill — they were due to lack of math. I'd skip a measurement,
