WHEELS AND TIRES
The wheels on the bike keep you in contact
with the road. They experience heavy loads
during riding over irregular surfaces and
when carrying cargo. Although the wheels
are carefully manufactured and trued, they
settle in after the first few kilometers. After
a short break-in period from 200 to 400 kilo-
meters, your dealer should true the wheels
again. Regularly check the wheels but ad-
ditional tensioning is rarely necessary.
CONSTRUCTION OF A WHEEL
The wheel consists of a hub, rim and spokes.
The tire is mounted to the rim in which
the tube is inserted. Rim tape is applied to
protect the sensitive tube from the often
sharp-edged rim.
TIRES AND AIR PRESSURE
The tire provides grip and traction on the
road which is required during braking, ac-
celerating, and cornering. Furthermore, it
ensures smooth running.
Both street tires (speed, road) and knobbies
(MTB) for rough tracks are available. Tires
can only work well if it filled to the correct
air pressure. The correct inflation pressure
also prevents failures such as the crushing of
the tube especially when traveling over an
edge, the so called “snake bite”. Snake bites
are caused when going over an edge such
as a curb with a tire pressure that is too low.
The manufacturer’s suggested pressure is
indicated on the sidewall of the tire in bar
and PSI.
PSI BAR
45 3,0
50 3,5
65 4,5
85 6,0
95 6,5
120 8,0

Always ride with the prescribed
air pressure and check it
regularly.
Never pump the tires over the
maximum recommended pres-
sure rating! The tire can spring
from the rim or burst leading to
an accident!
DANGER!
TIP!
Always ride with the prescribed
air pressure and check it regularly.
Because Riese & Müller bikes are
full suspension you can always
inate the tires to the maximum
recommended pressure. This pro-
vides you the best and safest riding
position and low rolling resistance
which saves energy. Comfort is
maintained because of the full
suspension system.
