Eights are the most common bicycle wheel defect and are experienced by most cyclists. Eliminating this defect takes time, however, if you know exactly what to do, then you can get rid of the figure eight without much difficulty.
Instructions
Step 1
The cause of the appearance of the figure eight, as a rule, is considered a strong blow, but in fact, the blow is only the final stage, and this defect occurs due to loose knitting needles. Therefore, in order to prevent the appearance of the figure eight, regularly tighten the knitting needles with a special key. However, if the figure 8 does appear, fix it with the same spoke tightener.
Step 2
Take a chalk or bright marker and hold it near the wheel rim (about 1mm apart). If you are not sure if you can hold the chalk or marker firmly enough, secure it with something. Then spin the wheel. A stripe will be drawn where the defect has occurred. Repeat the same on the other side of the rim and then you will see exactly where the defect appeared on the wheel. This method allows you to identify even outwardly almost imperceptible, implicit figure eight.
Step 3
The spokes in a bicycle wheel alternate: one on the right, one on the left, etc. Find the line you have drawn and the spoke on the other side of the rim that is closest to the center of that line. This knitting needle needs to be tightened while loosening two adjacent knitting needles. Please note: you need to tighten the knitting needle twice as much as loosen it. Be careful not to twist the knitting needles too much! First, you should tighten one knitting needle 1/2 turn, and loosen two adjacent ones by 1/4 turn. If the figure eight is between two adjacent knitting needles, tighten one knitting needle and loosen the other by the same number of revolutions (for example, by 1/3). If the figure eight is too large and captures several knitting needles at once, tighten and loosen them one by one, moreover, the central one is stronger, and the outer ones are weaker.
Step 4
After tightening the correct spokes, place the chalk or marker on the rim again and spin the wheel. If the figure eight has become smaller, twist the knitting needles a little more, and if it has become larger, return everything as it was and again, but even more carefully and accurately, tighten the knitting needles.
