        Bicycle circle is the most critical part of the bicycle, bicycle rims is left even the best parts do not allow bike run, therefore, master bike rims knowledge is particularly important. This paper describes a method for correcting distortion and bicycle rims, as well as the type of bicycle rims interface.
1. distortion and correction method of bicycle rims
Because car rims article broken or loose pieces caused by deformation of the vehicle, generally axial runout (RIMS swing) and meridional beat (RIMS jumping up and down). If the deformation is not too great in the car alignment, such as large deformation, the wheel can be removed, remove the tires, put on a flat circle is adjusted. Exclude axial runout method: First adjust the bearing position, tighten the screws looking rims axial runout of size and scope, make a mark on the rim or tire runout segment. If the swing to the right, pull the first beat with a bar on the right section of the faceplate pull too tight car bar to relax properly, pull too loose on the car and then left the faceplate pieces properly tightened; if beating the left, opposite adjustment method.
Excluded by the beat approach: first to rule out the heart beat, the beat on the left and right of the car segment faceplate tight strip alternately loosen; then exclude beat centrifugation, will beat a loose car segment strip alternately tighten. If the rim is still beating, in addition to adjusting the elastic strip runout segment car, you should also adjust the beat section near the car of the tightness.
Adjust the rim is a delicate work, each spin momentum strip cap nut not too much. Generally only allow one-quarter to one half swirling week, adjusted to the entire rim runout is less than one mm standard.
Due to the collision or wrestling, RIMS will produce serious distortions or "dead bend" when cycling training. When the car with elastic strip method can not be corrected, it can be rims, tires and car strip (or part) removed, with a wooden stick or hammer positive (when struck with a hammer to the mat wood, prevent smashed rims). If the distortion is large, the rims with both feet flat on the ground. The longitudinal direction of the bar will also be pressing short rim, or the minor axis direction of stretch. Then draw a circle with a diameter of 670 mm on the ground, to be checked. If the rims and the earth circles substantially coincide, indicating rim oval has been eliminated. Correction rim strip and then loaded on the train to the flat circle is precisely correct.
