43ROTWILD USER MANUAL | 2013
WHEELS
The basic components of the wheels of your
ROTWILD bike are the hub, the spokes and the
rim. The hub contains the quick-releases with
which your wheels are attached to the frame.
The inside of the rim contains the rim tape that
prevents the sensitive inner tube inside the tyre
coming into contact with the sharp-edged spoke
nipples. When mounting a new tyre, please
make sure you have the right dimensions (size
and width).
Tips concerning air pressure
Your wheels will only function perfectly when
the tyres are inflated to the recommended
pressure. This is usually printed on the walls
of the tyres.
A slight improvement in cycling comfort is
possible if you reduce the recommended tyre
pressure by 10-25%.
Always make sure there is enough air in your
tyres. Only in this way can you be certain that
the inner tube will not be pinched (Snake Bite)
when riding over sharp edged obstacles.
If you inflate your tyres at a filling station,
please take care to inflate your tyres in
short bursts of air and constant checking of
the manometer reading. These tyre pumps
provide high inflation pressure that could over
pressure and burst your bike tyres.
Use a so-called floor pump to pump up your

tyres at home. With this type of pump, it is
perfectly simple to ensure the appropriate
air pressure in your tyres. You can check the
pressure with a manometer.
Always take a hand pump along on every ride
to reinflate your tyres to the correct pressure
in the case of a puncture or loss of air.
Air pressure
Never pump up your tyres to a pressure higher
than the maximum permissible pressure. This
could cause tyres to burst or slip off the rims
while cycling.
Note
If it should become necessary to remove the
wheels for transportation, please take care
not to bend the brake disc located on the left
hand side of the wheel. A bent disc can lead to
uneven rotation in the calliper and abrasion.
When transporting the bicycle with the wheels
removed a transport safety device provided for
the purpose should be inserted between the
brake pads. This is to prevent the brake pads
from moving towards each other.

Air pressure units
As a rule, air pressure is given in Bar or the
English units PSI – see conversion table.
PSI BAR
20 1,4
30 2,1
40 2,8
50 3,5
60 4,1
Mounting and removing wheels
If you have to remove a tyre to repair a punc-
ture, or if you are preparing your ROTWILD
bike for transport, it may become necessary to
remove one or both of the wheels and remount
them later.
Note
Please note, the disc brakes become extremely
hot during braking. Let the discs cool for a while
if you intend removing the wheels shortly after
braking.
Removing wheels
Open the quick-releases.
As the forks have a drop-out protection on
the end, it is not yet possible to remove the
front wheel. The wheel can be removed by
unscrewing the tensioning nut on the end of
the quick-release by 3 or four turns.
