Components subject to normal wear and tear (e.g., tires, chain, brakes) are not
covered by the warranty.
The basic maintenance of the bicycle can and must be carried out
directly by the owner; does not require special tools or specific technical
knowledge beyond what is explained in this manual.
Here are some examples of interventions that you can perform yourself.
All other inspection, maintenance and repair services must be carried out
in a specialized centre by a qualified technician. Always contact the service
centre for any doubts or uncertainties.

Adjust the brakes

The bike is equipped with V-BRAKE brakes.
The right lever controls the rear brake. The left lever controls the front
brake.
When adjusting V-Brake brakes, maintain a distance of about 2 mm
between the brake pads and the rim. Both brake pads must touch the rim
at the same time during braking and without touching the cover.
Adjustments should be made by turning the adjustment screws on the
brakes. If you have any doubts or notice any irregularities during use, have
your bicycle checked by a competent mechanic.

necessary the handlebar turned to maximum), unscrew screw B slightly, avoiding that
the chain goes beyond the last chainring.

If the chain descends with difficulty on the small rear chainring, slightly
unscrew screw A to align the derailleur unit on the small chainring.
Bolts and nuts tightening
During use, due to vibrations, some screws may become loose. We
advise you to periodically check the tightness of the screws. Replace any
√
damaged or lost parts immediately. The following is a table of tightening
torques to be applied for the assembly of different types of components.
√
For each component, the "minimum-maximum" interval at which those
components are generally kept is reported. The table is purely indicative,
because we repeat that numerous variables contribute to affecting the
precise degree of torque to be applied to the various screws, such as the
material used for the screw and / or the type of thread, the sections and
√
the thicknesses of the material on which you act and of course the material
of the parts to be interfaced.
The tightening torques are expressed in Newton-meters; remember that
to correctly carry out this operation, a torque wrench is required, which
detaches when the desired torque is reached.

Running-in period

Your bicycle will be more efficient and will remain in optimal conditions for
a long time with a break-in period before continuous and intensive use.
Brake or gear cables, spokes and other mechanical parts may become
loose in the very first period of use and a change to the service centre may
be required for final adjustment.
