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 again and
again with the following process.
It is similar to the process as for horizontal
movement.
Be sure, in this case, you should tighten both side of
the nipples equally.

1.
You set the wheel on the True-Pro 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.
3.
Attach vinyl 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 vinyl
markers as below;
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 one between the vinyl tapes.
5.
If the rim moves to outward, tighten both side
nipples.
If the rim shakes inward, do NOT loosen the nipples
and tighten both far side nipples.
This is because the nipples are made of soft material,
so its thread can be broken easily by loosening.
6.
Tighten the spokes as below;
• Group-A nipples about 1/8 turns
• Group-B nipples about 1/4 turns
• Group-C nipples about 1/2 turns
Then check the vertical movement again with
rotating the wheel slowly.
If the wheel moves yet, continue the process again.
If you hear a strange sound or see
metal "lines" or residue, your nipple
will fail soon.
Do NOT apply any lubricant to quiet
the sound. Put a new nipple on
immediately.

How To Fix Horizontal Movement
The horizontal movement within 2 mm may not
cause any troubles. But if you want to be it as zero as
possible for smoother ride, you should try again and
again with the following process.
1.
You set the wheel on the True-Pro and see the Side
Gauges.
Put the tips of them close to the surface of the rim
side wall. Do not touch the rim.
2.
Rotate the wheel slowly, and check the horizontal
movement.
3.
Attach vinyl tapes to two spokes; one is in the
beginning and one is in the ending of horizontal
movement.
!
Do NOT tighten the spoke more
than 1/2 turns at one time. Wheel
truing must be done step by step.
Otherwise, you will loose the spoke
tension balance completely.
