Important Notes
• Use the supplied plastic tie to hold the pillar to the ceiling
or the wall to avoid the stand from toppling over if the pillar
length was shortened if there was an issue with the locking
bolt.
Minoura is not responsible for damage caused by misuse or
improper installation.
• For standard 2-wheel bike only. Not for use with tandems or
long wheel-base bicycles.
• Each bike cradle is rated to hold up to 25 kgs.
If mounting heavy bikes, check the cradle bolts often to make
sure they have not come loose.
• Check to make sure the Pillar Joint has remained secure by
pulling down the Upper Pillar after tightening the Pillar Joint
Bolt and the Lock Plate Bolt.
If the pillar has moved after tightening, discontinue using and
contact your dealer or Minoura distributor in your country.
You may need to replace the metal ring of the Pillar Joint.
• The pillar is supported by the internal spring applying
pressure to the ceiling.
Make sure that the pillar comes in contact with a stud or
other reinforced area of the ceiling otherwise the spring
pressure may cause damage to the dry wall or ceiling.

• Adjust the pillar length correctly. If the red plastic appears
beneath the Upper Rubber Cup, it means the pillar is not
adjusted properly (too short).
• Do not install the pillar upside down.
NEVER use BikeTower horizontally. It is for vertical use
ONLY.
• The pillar must be completely vertical, and not at any angle.
Failure to do so will cause the stand to fall.
• The rubber cap material may leave a mark on some ceilings
or oors.
We recommend placing a small piece of fabric, paper or
wooden plate between the rubber cup and the ceiling.
Do not use a slippery material such as a Vinyl sheet.
• The coating on the cradle hook may leave a mark on your
bicycle frame.
We recommend wrapping a piece of bar tape on the hook
where it comes in contact with the frame.
• Depending on the bike size, you may have to change the
clamp position from the fatter Upper or Lower Pillar to the
narrower Center Pillar.
In this case, install the supplied gray plastic shim between
the clamp and the pillar.
•
The pillar is just a single pole so it's easy to turn. Do not place
any fragile items or sharp edge articles around the pillar.

About Center Pillar Insertion Depth
The BikeTower25D is constructed with two fatter pillars and single
narrower pillar combination.
The center pillar must be inserted into the upper or lower pillar at
least in the depth until the MAX decal becomes invisible. In this
condition, the pillar will have enough strength to support the load.
We strongly recommend you to insert the center pillar into both
the upper and lower pillars in the same length that would provide
maximum stability.
If the center pillar is not inserted evenly into the upper and lower
pillars, the balance of the stand will be off and could compromise
the overall stability of the stand.
Please be sure
the MAX
decal is put on
both top and
bottom end
of the Center
Pillar.
This tells you
need to insert
the Center
Pillar into the
Upper or the
Lower Pillar
in the depth
at least this
red indicator
becomes
invisible for
your safety.

For your reference, if your room's ceiling height is 2.4 meters (7.9'),
you should insert the center pillar in the depth of 25 centimeters (10").
It will give you the proper insertion ratio.
Calculation Of Tightening Torque
If the hex wrench length is 75mm,
pull the wrench tip with the power
of 107N (11 kgf) to expect 8 N.m
tightening torque.

The Lower Pillar must be fully inserted
into the Pillar Joint.
If some clearance remains, the pillar
may be too short and could fall down,
causing a serious accident.
