The crossover point is right in the popular range of sizes used for bicycle spokes: Get the chain out of the way before working on the rear wheel.

Aug 09, Josh rated it really liked it. In the case of derailer rear wheels, only the right-side spokes and spoke holes need to be lubricated. Because the nipples point straight inward from the rim, they can turn more easily in most rims than when they are bent to a slight angle by a semi-tangent spoke pattern. This is much easier to do on straight-gauge spokes, because they are stiffer torsionally, and it is easier to feel the twist than it is with butted spokes.

Hoped for additional cross lacing patterns and algorithms; Instead I got to under why I ought not re-invent the wheelbuilding process. There are three reasons for this:.

These peak stresses can be relieved by momentarily increasing spoke tension and stressso that the high stress points of the spoke yield and plastically deform with a permanent set. Once there begins to be a little bit of tension on the wheel, you should start bringing it into shape. Dec 25, Evans Liolin rated it it was amazing.

You can find them via DejaNews. Nov 02, Ben rated it it was amazing. When you buy spokes to match the rim, hub and pattern you will use, your dealer should be able to determine the correct length s for you. Read a section from a heading to a heading — they’re all short, because Jobst doesn’t waste any words — and ponder his points on your ride. As viewed from the right sprocket side of the hub, the key spoke will run counterclockwise, and it will go to either the hole just to the right of the valve hole as illustrated or the second hole to the right, depending on how the rim is drilled.

Since the holes in the hub flanges must be large enough for the threads to fit through, the holes, in turn, are larger than the wire requires. I’ve built several wheels since getting this book and it’s invaluable as a reference for that.

Why build wheels?

The wheel will gradually get truer and truer as you go. For extremely large hubs such as electric-bicycle hub motors, you may need to use a special spoking pattern. Rim brakes slowly wear down the sidewalls of aluminum rims, especially in wet-sandy conditions. Since spokes use rolled, not cut threads, the outside diameter of the threads is larger than the base diameter of the spoke wire.

Jan 05, Richard Hakes rated it it was amazing. Sep 04, Christopher Grande rated it really liked it Shelves: Part II is a step by step guide to building wheels. Leading a motley crew of co-contributing fellow investigators, Jobst fleshed out the true nature of the tensioned wheel and recorded the details for all of us. The best wheels can be built by those who’ve thoroughly assimilated The Bicycle Wheel; Sheldon Brown, the great bicycle mechanic, believed it too, and collated Jobst’s thoughts on other matters of importance to cyclists at http: Topics like this can be hotly discussed on newsgroups, and it can sometimes be hard to judge which side is right.

Carbon fiber rims also are expensive. These are the spokes that exit the hub in the direction of rotation. Language Choose an option English German Clear. Ark rated it it was amazing May 01, 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.

Blog Store Library About Contact. Lower cross numbers make the spokes more nearly perpendicular to the hub flange, and to the rim. These curves will gradually straighten themselves out over the first few hundred miles on the road, and the wheel will lose tension and go out of true.

In the early ’80s a clever marketeer hit upon the idea of using only 32 spokes in wheels for production bikes. This is not an important issue!

He is kind of a genius, so don’t take offen This is easily the best book written on the physics of bicycle wheels. While these guides told me what to do, they didn’t tell me why.

More important is that it be even.

Their wheels were highly dished inward, and were laced in the same half-radial pattern, for the same reason. My favorite lever for this is an old left crank: For front wheels, disregard that which does not apply.

The length is not super-critical, but it is worse to have spokes a bit too long than a bit too short. I don’t recommend leaving spokes slacker than their optimum.

This ease of turning increases the risk of their unscrewing themselves on the road. Unfortunately, they turned out to be prone to breakage, and I can’t recommend them.

Maybe I was just being thick when I came across it: Start at the valve hole and work your way around until you get back to it, so that you won’t lose count. I also would have liked descriptions of other types of lacing besides 3 cross, but still it was quite good for what it was. Now you are ready to put the wheel into the truing stand. Building wheels from scratch bramdt the best way to learn the craft whheel wheel truing, to get the feel for how a wheel responds to spoke adjustments.

Generally, I round upward to the nearest available larger size.
