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

the kit. Purchase sseparately if necessary.
• Dishing Tool and Nipple Wrench are
necessary for maintaining the wheel but
they are not included in this kit. Purchase
them separately at your local bike shop.

Thank you for choosing the MINOURA
BASE
True-Base holds a bicycle wheel on top of the pillars
for helping you to maintain the wheel.
The gauges that check vertical and horizontal
movement of the wheel are intuitive and easy to use.
True-Base folds down completely for easy trans-port
and compact storage.
Please read this instructions manual carefully before
use and keep handy at all times for future references.

Important Notes
• Do NOT use True-Base for any purpose
other than instructed such as displaying
bike on it.
• Both right and left side pillars move
together for placing the wheel in the same
position whatever the hub width is, but it's
not 100% perfect so we recommend you to
use an optional wheel dishing tool together
for much more precise adjustment. We
don't guarantee any result by using this
stand.
• Axle Holder is a xed type. Depending on
the hub width, you may have to slightly
bend Axle Holder by tightening the

• 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
Be sure that Axle Holder is a xed type, not angle
adjustable.
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-Base to get better result.
If one side has been lifted up due to bad installation,
the wheel won't become symmetrical.

How to Operate
!
Checking Position
Foldable Vertical
Gauge
(Fig. C)
(Fig. E)
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 for getting clearer sound.
(Fig. D)
• 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 red barrel
type Vertical Gauge Adjust Knob. (see Fig. C)
Vertical Gauge should be positioned 1 - 2 mm away
from the rim. (see Fig. D)
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 only, you can fold down the
Vertical Gauge manually. (see Fig. E)
Vertical Gauge may be twisted
slightly.
It must be parallel to the rim, and
both right and left side of the rim
edge must touch Vertical Gauge at
same time.
If it has been twisted and you see
some gap on either side between the
gauge and the rim edge, pinch the
gauge only (not holding the barrel
knob) then turn it.
• SIDE GAUGE
Side Gauge is for checking the horizontal movement
of the wheel. When the rotating wheel comes
in contact with the Side Gauge, you will
scratching sound.
To adjust the opening of Side Gauge, rotate Side
Gauge Adjust Knob, then both Arms will move
together at the same time. (see Fig. C)
Side Gauge should be positioned 1 - 2 mm away
from the rim side wall. (see Fig. D)
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. F)
The metal tip of the side gauge can be retracted
by ipping the tip metal piece if you worry about
damage to the side of your rim. (see Fig. G)
However, the contact sound will have to become
smaller so listen more carefully.
How To Fold Down
