When you exchange tires please note the ma-
ximum width limit of 50 mm (approx. 2 ").We
recommend tires that are 32-40 mm wide.At
the front wheel you have to use tires of ISO
size 406 (20"), at the rear wheel ISO size 559
(26").The tire width possible at your bicycle
depends on the size of your rims. Please ask
your local dealer.
After you have exchanged the tires please
check if the wheels turn freely and check the
minimum distance between mudguards and
frame.
The spokes of the wheels connect the rim
with the hub.With disc brakes and at the rear
wheel they additionally transmit the braking
power and the pedal forces.
The wheels are fastened with a quick release
lever and therefore they are susceptible to
theft. For this reason always lock the wheels
along with the frame to a solid object when
you park your bicycle somewhere. It is also
possible to exchange the quick release axles
with axles that have special security locks (e.g.
P
ITLOCK or KRYPTONITE) that can only be ope-
ned with a special tool.
Cleaning and conservation
The frame of the Street Machine GT has a
high quality and environmentally friendly pow-
der coating.The surfaces of the aluminum
parts are either polished or anodized.
To keep the surfaces brilliant over many years
and to protect them effectively against corro-
sion the bicycle has to be cleaned from dirt
and then conserved.
Dried sweat but also environmental influences
such as air pollution, dirt on the roads and es-
pecially grit affect the parts, and not only do
they result in visual faults but also in serious
structural damage of the parts through corro-
sion.
In contrast to a widespread belief particularly
the "non-rusting" aluminum is dramatically af-
fected by grit! This kind of damage may not be
visible in the beginning but it leads to a serious
danger when the part breaks.
Wheels, Cleaning and conservation
Danger! Check your tires for damage on a
regular basis.You should exchange tires with
worn threads or damaged sidewalls.
Damaged rim tapes have to be exchanged
immediately. Damages at the tires may lead
to a sudden burst of the tire and thus result
in a serious fall.
Danger! Take care that your spokes are al-
ways in perfect condition and the spoke ten-
sion is balanced. Do not ride with wheels
that run untrue or wheels with loose or
missing spokes.These faults may lead to a
total failure of the wheel while braking and
result in a serious fall!
Caution! To true up the wheels you need
special skills, please have this work done by
an experienced bicycle mechanic.
