All dimensions are in mm, and weight in grams. All listed dimensions may vary in tolerance. A typical good quality millimeter open-end wrench or six-inch adjustable wrench is about seven millimeters 0. Cone wrenches, however, are usually only two millimeters 0.
In most cases, a standard open-end or adjustable wrench can be used for cone locknuts, but the cones themselves can be adjusted only with a cone wrench, because of narrow flats and close clearances.
Cone wrenches usually come in 13 x millimeter, 15 x millimeter, and 17 x millimeter sizes. If you intend to do your own maintenance, you should have at least one and preferably two of each size needed for your hubs. The safest way to buy cone wrenches is to ride your bicycle to a well-stocked bicycle shop and check the fit as you are buying the wrenches.
Cheap tools are never a bargain, and this is especially true of cone wrenches. Because of their extreme thinness for the nut sizes they fit, cone wrenches must be made of especially high-quality steel to stand up to the normal stresses that they will be subjected to in use. Inferior cone wrenches will bend, often the first time that they are used, and so become useless. As with so many other bicycle tools and parts, Campagnolo is the standard for comparison.
I have been using my Campagnolo wrenches for 12 or 13 years now, and they still fit as well as they did when they were new. I bought the Campagnolo wrenches after going through several sets of cheap French cone wrenches in just a few' months of professional use. At that time, I could find nothing else that would hold up to serious use. In the past few years, however, quite serviceable cone wrenches have become available from American and Japanese manufacturers at reasonable prices.
In general, you will get better quality tools if you buy them individually, rather than buying a pre-packaged "bicycle tool kit. Schwinn makes particularly good cone wrenches for shop use. They are single-ended, with a comfortable plastic-coated handle. Unfortunately, since they are single ended, you need to buy ten of them to get two each of the five common sizes.
I have yet to find a need for the millimeter end of my 17 x millimeter wrench. My current favorite is the Park laser-cut black finish shop model. There are times when two cone wrenches of the same size are essential -- for instance, Campagnolo Record rear hubs use a millimeter wrench for both the cones and the locknuts; the locknuts have narrow flats and taper in such a way that you must use a cone wrench for the locknut as well as for the cone.
Even when two identical cone wrenches are not essential, they are a great aid in adjusting the cones quickly and exactly. If you do not have two of each needed size, to make even the smallest change in the cone adjustment, you must first loosen the locknut, then adjust the cone, then re tighten the locknut.
If you get the cone adjustment just right but the locknut is not sufficiently tight, tightening the locknut will throw the cone adjustment off. Careful cone adjustment by this technique is a very time-consuming process of trial and error. If you have two wrenches of each needed size, the fine adjustment can be done much more quickly and easily!
