What are the knitting needles for a bicycle

The spokes in the bicycle wheel are necessary in order to connect the bushing with the rim. Thus, they ensure the integrity of the structure and its strength. Among other things, the spokes play to some extent and a cushioning role. Some flexibility of this structural element ensures distribution of load along the rim of the wheel.

The spokes for a bicycle consist of two parts - this is the actual rod and nipple (mushroom-shaped nut for fastening on the rim). This design provides a completely secure mount. One end of the rod is bent and riveted. On the second there is a thread, which can be threaded or rolled. The second option makes the spoke stronger and more reliable. Thread thread more weakens this part, which often breaks precisely in this place. The rod is made either from high-alloy steel or from ordinary (with nickel-deposited). The second option is less reliable. For sports models, titanium variants are often used.

The nipple is made of bronze, steel or aluminum. The first option is preferable in the sense that it practically does not boil. Replacing the spokes on a bicycle when using such nuts can be more simple. Steel elements are the cheapest, and experts do not advise them to use. The most expensive option is aluminum nuts. They make it easier to make the wheel.

Spokes for a bicycle of the usual urban type are applied in an amount of 36 pieces. In the wheel of road models, there may be less of them. Thus, a greater maneuverability of the bicycle in terms of changing speeds is achieved. In different designs, the number of spokes may not be the same. However, their number is always a multiple of four or two.

In addition, the bicycle spokes can have different thicknesses. In the front wheel, the sleeve flanges are symmetrical, they have a standard size. In the rear, the multi-speed design, on the contrary, is asymmetric. Therefore, the dimensions can be absolutely any. Therefore, on models with the same types of bushings, the spokes designed for the front wheel, for the rear right and for the rear on the left are installed. They have different thicknesses.

Sometimes you need to replace or adjust the spokes of a bicycle. These operations are rather complicated, but can be performed independently if desired. In order, for example, to tighten the spokes, you need to turn the last upside down with wheels and pozhatat rods. If the amplitude exceeds 1-2 mm, it is necessary to tighten the element. It is more difficult to prevent the appearance of the G8 when pulling. For this it is necessary to determine the amplitude of the horizontal and vertical runout. Eliminate these problems by tensioning or loosening the spokes and displacing the rim. In the same way, correct the ellipse of the rim.

Replacement of knitting needles can be necessary as a result of its breakage. Most often this happens with a strong impact, for example, on the log or the edge of the pit. This sometimes happens, and therefore it is worthwhile to have spare spokes for a bicycle. In order to reach home, in the event that there are no tools for removing the wheel, the broken part is bent and the wire is tied to it. This way you can get to the place where it is possible to replace the spoke with a new one. The latter is simply inserted into the rim and twisted by a nipple.
