[. . . ] Then open the U-shaped gauge frame at right angles. ference of the centering position, it may not cause any troubles. GAUGE FOR SIDE SHAKING The gauges for side shaking are located on the both side of the U-shaped gauge frame, they are the knob bolts. They have 0. 1mm level scale on their own surfaces. [. . . ] The thread of the nipple and the spoke is not so stronger than you think. And you must use a special spoke wrench which fits the nipples perfectly if you use light alloy nipples on your wheel. If you use wrong one, the nipple will be round easily and you cannot continue your work any more. · About Offset Wheel Setting At first, you should understand that you should fix the vertical shaking prior to the side shaking, especially on the rear wheel because of its unique wheel system "offset". · How To Fix Vertical Shaking The vertical shaking within 3mm may not cause any troubles. But if you want to be it zero, you can try again and again with the following process. It is similar to the process as side shaking. In this case, you should tighten both side of the nipples equally. You can see a gauge plate on the U-shaped gauge frame. Put the tips of the plate close to the surface of the rim. Rotate the wheel slowly, and check the vertical shaking. And stick vinyl tapes to two spokes; one is in the beginning and one is in the ending of vertical shaking. Make three groups of these spokes between the vinyl tapes as below; Group-A : Three or less spokes in the beginning and in the ending of vertical shaking. Group-B : Three or less spokes between Group-A except for the center one. Group-C : The center one between the vinyl tapes. Offset Wheel In the front wheel, it is very easy that you can tension all spokes equally with ignoring the direction of right and left. However in the rear wheel, you have to select another process; offset tensioning. You can notice that the rear wheel has different spoke angle pattern with looking at the wheel from behind. Rear hub is not symmetrical to the wheel, left side flange is far from the wheel centerline, and right side flange is deep in the wheel. Because rear hub must have extra space where the transmission gear will be located. But you have to assemble rear wheel symmetrically in this strange situation for its stable balance. In offset wheel, the torque works only to the right side spokes. Because right side spokes should be assembled more vertically than left side. So you should understand that right side spoke tension is more important than left side spoke's one in this offset assembling. Well adjusted right side spokes Rotate the wheel slowly, and check the side shaking. [. . . ] If the wheel shakes yet, continue the process again. When you hear strange sound from the nipples or see some kind of strings while you tighten the spokes, the thread of the nipples will be broken soon. But do not apply any oils to the nipples to remove the sound, and try to exchange the nipple to the new one as soon as possible.
