This portable wheel truing stand features our
convenient AUTO CENTERING system. ACS
allows you to perform almost every procedure
needed in building a wheel without the need for an
additional dishing tool.
Also, newly designed gauges that check vertical and
horizontal movement of the wheel are intuitive and
easy to use.
TRUE-PRO folds down completely for easy trans­port and storage.

Please read this instructions manual carefully before
use and keep handy at all times for future references.

Components

Vertical Gauge

• PILLARS

Both right and left side Pillars are connected in the
Body so they will move together at the same time.
You should hold both Pillars with both hands when
opening or closing them.

• AXLE HOLDER

Axle Holder can adjust its angle to keep parallel at

any width to t hubs properly. (see Fig. A)

It is crucial to set the wheel into the deepest position
of the Axle Holder by pushing down the wheel when
setting up the wheel on True-Pro to get better result.
If one side has been lifted up due to bad installation,
the wheel won't be symmetrical.

Important Notes

• Do NOT use True-Pro for any purpose other
than instructed such as display stand or
indoor trainer.

• This Auto-Centering system is not 100%
perfect so we recommend you to use a
wheel dishing tool together for much more
precise adjustment.

• Setting wheel in the correct position is
crucial. Push down the wheel to set it in
the deepest position on the Axle Holder
when you tighten the quick release skewer.

How to Operate

Checking Position

Foldable Vertical
Gauge

(Fig. B)

(Fig. D)

The metal tip on the Vertical Gauge can be removed
by loosening two screws if you don't wish to scratch
the soft carbon rim surface.
However, we recommend you keep the metal tip in
contact at all times.

(Fig. C)

• VERTICAL GAUGE

Vertical gauge is for checking the vertical movement
of the wheel. When the rotating wheel comes in
contact with the Vertical gauge, you will hear a
scratching sound.

To adjust the gauge position, rotate the Vertical

Gauge Adjust Knob. (see Fig. B)

• SIDE GAUGE

Side gauge checks for horizontal movement. Spin
your wheel and

a scratching sound.

hear

To adjust the opening of Side Gauge, rotate Side
Gauge Adjust Knob, then both Arms will move

together at the same time. (see Fig. B)

Side Gauge should be positioned 1 - 2 mm away

from the rim side wall. (see Fig. C)

If the movement is so heavy, you should place the
gauge farther, then set it closer gradually as the
adustment is being done.

If you already set the best opening size of the Side
Gauge to your rim but the wheel has a tire, you can
open the Arm manually for quicker installation.
To do so, hold the Arm then open it until it is locked

at the widest position. (see Fig. E)

Vertical Gauge should be positioned 1 - 2 mm away

from the rim. (see Fig. C)

If the movement is so heavy, you should place the
gauge farther, then set it closer gradually as the
adustment is being done.

If you mount a wheel with tire for just checking the
horizontal movement, you can fold down the Vertical

Gauge manually. (see Fig. D)

The metal tip of the side gauge can be retracted by

turning the screw and tip if you worry about damage
to the side of your rim. However, some contact must
be maintained so you can hear if the wheel needs
adjusting.

How To Fold Down

True-Pro is completely foldable for easier
transportation and compact storage.
To fold down, follow the steps;

(Fig. F)

(Fig. G)

The T-Gauge2 checks the position of your True-Pro
to make sure it is centered exactly so your wheel
should be able to be trued as symmetrically as
possible.

It's crucial to check the gauge position at the
point where you work on the actual wheel.

Also you should check regularly before using True­Pro to avoid mistakes.

1. Shut the Side Gauge as narrow as possible.

2. Loosen the Lock Knob.

3. Open the Pillars slightly.

4. Fold the gauges downward and push toward the

Pillars.

5. Flip up the Leg until it touches the Gauge Stay.

6. Tighten the Lock Knob.

7. Close the Pillars until it touches the gauges.

Be careful not to pinch your ngers

between the body, stay and leg.

T-Gauge2 Setup
Position

T-Gauge2 should be installed on the Axle Holder as
deep as the case of wheel.
Loosen the knob nut, insert into the Axle Holders.
Make sure each metal washer is located inside of the
Axle Holder to keep the angle as vertical as possible.
While pushing down the T-Gauge2, tighten the knob

nut to x the position.

Put the Side Gauges close to the T-Gauge2, then shut
the Side Gauges by turining the adjust knob.
