TENSIONING SPOKES
§ ABOUT SPECIAL TENSIONING OF
THE REAR 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 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 assembled
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
can keep your wheel stable in the future. Left side
spoke tension is just a help.
§ TENSION RIGHT SIDE SPOKES
At first, you have to take care of right side spokes only.
Left side spokes will be adjusted after this process, so
now you don't have to worry about them.
We suggest that you have to tension all spokes equally,
so that you should start all tensioning from the spoke
next to the valve stem hole.
And we suggest that you can tighten the nipples, but
you should not loosen them during tensioning and tru-
ing. The threads of the nipples and spokes are not as
durable as you think. You can try once only.
1.
Install the assembled wheel on a wheel truing stand.
Spread arms of the truing stand and insert the hub shaft
into the hollow of the top of the arm.
Fix the quick release lever or tighten the hub nut slightly
with pushing down the wheel.
In this instructions, the drive side is in the right.
In this time, make sure that the wheel is installed cor-
rectly to the truing stand. You will not be able to finish
this process with slanted wheel installation.
And take all gauges of the truing stand away from the
wheel now.
We will explain how to use the wheel truing stand in the
following pages.
2.
Rotate the wheel slowly, and tighten the nipples, which
are connected to the drive side of the hub flange, equally
by your finger until these nipples are tight.
3.
Tighten the nipples equally with a spoke wrench little
by little.
You should make sure that you don't tension all spokes
completely, because you will have to tension the other
side spokes later.
4.
After you finish this work, check the vertical shaking of
the wheel first.
You can ignore the shaking within 3mm now, it is just a
habit of the rim. It will not cause any troubles. But if
the vertical shaking will be appeared more than 6mm,
you may not use this wheel in a race to prevent acci-
dents.
