Make sure that your brake discs are correctly mounted
between the brake pads. Check the distance between
the pads and the brake disc.
Please also make sure that your belt drive and gear hub
are properly mounted and adjusted.
Check the position of the valve. It must be located
within the wheel with its tip pointing to the hub. A valve
which has been installed in a diagonal position could
tear off and result in sudden loss of pressure.
Before the tube is fully inflated, you should probe
the entire circumference of the tube with both hands
to ensure that it is properly positioned in the tyre.
Once you have checked the position of the valve and
the tube in the tyre, you can inflate the tyre to the air
pressure specified by the tyre manufacturer.
Check the position of the tyre using the control ring on
the tyre side wall. It must exhibit the same distance to
the rim across the entire circumference.
Mounting the wheel
Reverse the steps for removing the wheel in order to
mount the wheel. Make sure that your wheel is mounted
in a central position between the forks and the rear
frame.
Make sure that the quick release, the fastening screws
and the non-turn washers are properly positioned, also
in the failover protections of the front forks. Please read
the chapter ‘Handling the quick releases or quick
release axles’ on p. 24.
Brake function.
Assembly errors and contamination
with e.g. oil and grease on the brake discs and brake
pads, may negatively effect the function of the brakes.
Test the brakes regularly.
WARNING
Headset
The headset is a rotatable interface between the front
forks in the steerer tube. During use, the headset is
subjected to considerable forces and torques, which
may loosen the bearing.
To check the headset play, place your finger around
the upper bearing shell. Apply the front brake and
push your bike to the front and back forcefully.
If the bearing exhibits play, the upper bearing shifts
with respect to the bottom shell.
To check for unrestricted headset movement, lift the
front wheel on the front frame triangle and steer to the
left and right. This movement must be performed with
very little resistance. Centre the front wheel and tilt the
bike slightly to the side. The front wheel must fall to
the side on its own.
Loose headset.
A loose headset may increase
stress on the bearing and the front fork, which
may result in a fracture. Check the headset play
on a regular basis.
Loose stem.
A loose stem may cause a crash.
Check to make sure the stem is securely positioned
by holding the front wheel between your legs and
attempting to turn the handlebars. The handlebars
may not twist in the process.
Only specialists should adjust the headset.
Special tools may be required in certain cases.
Have the headset adjusted by a bike specialist.
