This graph is an example of the topnotch information you’ll find in the book. Time to build my own wheels I used this book to build two wheels for my bike with little fuss. This book will give you the understanding you need to sort out these arguments.

Besides the essential tools, a spoke tensiometer picture, right and an electric screwdriver with an appropriate bit are helpful. It should speed up the learning curve.

Why build wheels?

It took a fanatical rider and gifted engineer Jobstan academic community Stanfordan energetic and curious cycling scene Bay Areafor such a breakthrough work. If you are on a tight budget, read the section of this article on truingso you know the technical terms, and then check out the section near the end weel this article on improvised tools.

After cold forming, steel always springs back a certain amount spokes are entirely cold formed from wire. Cyclists who choose jjobst build wheels often want something more than ordinary, but just building wheels conventionally is not a trivial task if a durable wheel is the goal. Jobst Brandt is a mechanical engineer Stanford with extensive experience, having worked for Porsche automobiles, Stanford Linear Accelerator Center, Hewlett-Packard and Avocet bicycle products.

For vertical truing, find the highest high spot on the rim. Many good quality rims have ” eyelets ” or “ferrules” to reinforce the spoke holes.

The Bicycle Wheel

The true contribution for the new wheel builder is to build conventional wheels exceptionally well. It takes a larger adjustment to affect the vertical truing than the horizontal truing. This particular technique has the added advantage of bending the spokes neatly around each other at the crossing, so they run straight from the crossing in both directions.

If your shop doesn’t have a piano, and you don’t have perfect pitch, you can compare wheeo with a known good wheel that uses the same length of spokes. Doubling the number of spokes on the right side of a bicycle wheel might also be used to optimize tension — for example, a wheel might have 24 spokes on the right side and 12 on the left — though at the expense of special rim and hub drillings.


Review of The Bicycle Wheel

People very rarely have trouble with front wheels:. Bkcycle bicycle mechanic and technical expert Sheldon Brown called it “the near-definitive text on the theory and practice of building spoked bicycle wheels. Part II is a step by step guide to building wheels. I might better have taken the loss of true as a red-flag warning.

It is best not to try to do this all at one sitting, because jobsg are likely to get frustrated at the slowness of the truing and tensioning process.

It may be disappointing to discover that “it’s all been done before” and that conventional wheels are a result of a hundred years of refinement. All through the writing is precise and direct. To avoid dishing problems in a rear wheel, you might just try the ShelBroCo 5 and 5 system. This page by Graham Moult lists dimensions for a large number of internal-gear hubs. According to one report, this was from a stroke while he was in the hospital, rather than the crash itself — though he famously did not wear a helmet.

Jun 03, Peter rated it it was amazing Shelves: A gift for an aspiring apprentice? If the spokes are still very loose, so that you can wiggle the rim back and forth easily, tighten each spoke one full turn. The other potential problem with radial wheels is that the spokes, trailing straight outward on the hub flange, can possibly rip the outer edge of the flange right off along the line of the spoke holes.

For front wheels, disregard that which does not apply. Open Preview See a Problem? You’d be surprised how much juice is to be squeezed out of a short paragraph by the cleverest engineer to take an interest in bicycles since Mikhael Pedersen. As a result, when the wheel is subjected to sharp localized stresses, the most heavily-stressed spokes can elongate enough to shift some of the stress to adjoining spokes. This is true even when the concepts are non-intuitive, such as “a wheel supports its load on the bottom few spokes”.

Topics like this can be hotly discussed on newsgroups, and it can sometimes be hard to judge which side is right. He is kind of a genius, so don’t take offen This is easily the best book written on the physics of bicycle wheels. About time for your own copy?


If you are cutting the spokes to take apart a wheel, be sure to remove brandh thread-on sprocket, freewheel or brake drum first. You solve this problem by sliding a small washer onto each spoke before inserting it into the hub.

Spoke nipple heads or access holes in the bottom of the rim must be covered with a rim tape, so they can’t puncture the inner tube. They help greatly in explaining the concepts. Flange thicknesses vary, but the spoke’s elbow should be snug against the flange. These are not the only possibilities, but they are the practical ones. Although this article was originally directed to shop mechanics, a knowledge of wheelbuilding can be invaluable to any cyclist who wishes to do his or her own maintenance and repair.

Translations of this article earlier version: Spring-back occurs because part of the material exceeded its elastic limit branct part did not. He is not always right — but almost always. Too wide, and it rides up on a bead seat of the rim as shown in the photo below, brnadt the tire from seating correctly. With some rims, the spoke hole just forward of the valve hole is offset to the left, with others it is offset to the right as illustrated. Now turn the wheel over and examine the hub.

Once the bicjcle is laced, adjust all of the nipples so that each is screwed equally far onto its spoke. Or, if a rim does not have recessed spoke holes, the rim tape and air pressure in the inner tube will keep the spokes from turning — at bifycle with a high-pressure tire. For extremely large hubs such as electric-bicycle hub motors, you may need to use a special spoking pattern.

Continue bringing up the tension one full turn at a time until the wheel begins to firm up.
