About Offset Wheel Setting
(Fig. J)
At first, you should understand that you should
fix the vertical movement prior to the horizontal
movement, especially on the rear wheel because of
its unique wheel system named "Offset".
Offset Wheel
Tensioning the front wheel is much easier than
the rear. Rear wheel tensioning requires Offset
Tensioning.
The rear wheel has a different spoke angle pattern
when looking at it from behind. (see Fig. J)
A rear hub is not symmetrical to the wheel. Flanges
can be far from center. Because the rear hub must
have extra space for the set of transmission gears,
you will need to true using Offset Tensioning.
If offset wheel, the torque works mostly only to
the right side (gear side) spokes. Because right side
spokes should be assembled more vertically than left
side.
Understand that right side spoke tension 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.
The nipple should not be loosened at any time.
Nipples are made from softer alloys or brass and are
prone to stripping easily.
You must use a correct spoke wrench
which fits the nipples perfectly,
especially when you use light alloy
nipples on your wheel.
If you use wrong size one, the nipple
will become round easily and you
cannot continue your work any more.

How To Fix Vertical Movement
The vertical movement within 3 mm may not
cause any troubles. But if you want to be it as zero
as possible for smoother ride, you should try the
following process again and again.
Be sure, in this case, you should tighten both side of
the nipples equally.
1.
You set the wheel on the FT-1 and see the Vertical
Gauge.
Put the tip of the Vretical Gauge close to the surface
of the rim.
2.
Rotate the wheel slowly, and check the vertical
movement. Do not spin fast.
3.
Attach tapes to two spokes; one is in the beginning
and another one is in the ending of vertical
movement.
4.
Make three (3) groups of spokes between your tape
markers as below;
A
B
C
B
A
(Fig. K)
Group-A: 3 or less spokes in the beginning and in
the ending of vertical movement.
Group-B: 3 or less spokes between Group-A,
except for the center spoke.
Group-C: The center 1 or 2 between the tapes.
5.
If the rim moves to outward, tighten both side
nipples.
