Then you can fold the Workman Pro.  Make sure that

you do not pinch your finger in the frame or the stay.

Finally, raise up the U-shaped gauge frame until it is

parallel to the gauge stay.  And tighten the knob bolt

again to fix the gauge stay.

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”.

can keep your wheel stable in the future.  Left side

spoke tension is just a help.

Also you should understand that the nipple is not al-

lowed to be loosened, you can tighten the nipple only

because the nipple is made of soft material such as

light alloy or brass.  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.

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 shak-

ing.  And stick vinyl tapes to two spokes; one is in the

beginning and one is in the ending of vertical shak-

ing.

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.

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 se-

lect 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 sym-

metrically in this strange situation for its stable bal-

ance.  It is offset.

In offset wheel, the torque works only to the right side

spokes.  Because right side spokes should be as-

sembled more vertically than left side.

So you should understand that right side spoke ten-

sion is more important than left side spoke’s one in

this offset assembling.  Well adjusted right side spokes
