Belt drive
If you bicycles comes equipped with
a converter, which makes it possible
to operate hydraulic brakes with me-
chanical brake levers, read the attached com-
ponent manufacturer’s operating instructions
before using it.
Wheels
Checking the wheels
The bicycle is connected to the ground by the
wheels. The wheels are subject to a great deal of
strain through the uneven characteristics of the
ground and the weight of the rider.
Thorough checks and centring work on the
wheels is undertaken before they are shipped.
However, during the first few kilometres of riding,
the spokes bed in.
• After the first 100 kilometers, the wheels have to
be checked by a specialist and centered again
if required.
• The tension of the spokes has to be checked
at regular intervals. Loose or damaged spokes
have to be replaced or centered by a specialist
retailer.
The wheels can be fixed in the frame and fork in
different ways. Commonly, the wheel is attached
with an axle nut or a quick release. In addition,
there are also various thru axle connections which
are screwed in or fixed with various quick release
systems. When a quick-release axle is fitted on
your bicycle, you can find more information in the
enclosed manufacturer’s operating manual or on
the respective manufacturer’s website.
All screw connections must always
be fastened with the correct torque.
If the torque is not correct, the screws
could break or loosen other parts (see page
37 “Torque for bolted connections”).
Checking the hubs
You can check the hub bearings as follows:
• Lift the wheels up from the ground by first lifting
the bicycle at the front then at the rear. Push
each wheel to start then turning.
• The wheel should continue to turn and then
slow evenly. If the wheel suddenly stops, the
bearing is defective. One exception is front
wheels with a hub dynamo. They have a slightly
higher resistance to rolling. However, this can
hardly be noticed during normal riding.
• The hub bearing should not exhibit play. Pull
the wheels in the front and rear fork lightly to the
sides to check if they are loose. No play may be
noticeable.
• If the wheels can be slightly moved in their
bearings or are difficult to turn, the hub bear-
ings have to be set up by a specialist retailer.
Rims/Tyres
Normal operation wears down brake
rubbers and brake pads. You should
therefore regularly check the condi-
tion of your braking system and brake pads!
Replace worn brake pads and rubbers in
good time!
Ensure that rims and brake discs are clean
and free of any oil!
Regularly clean the rims according to the in-
spection plan, page 34. Check the wear markers
during that process:
Modern rims (from 24’’) indicate when
they are worn from breaking. These
indicators take the form of embossed
or coloured points or lines on the brake sur-
faces of the rims. When these disappear, you
are no longer permitted to use the rims. There
are also similar indicators which only appear
after a certain level of wear. At the very latest
when two pairs of brake rubbers have been
worn, it is necessary to have the rims check
by a specialist retailer.
