WHEELS, TYRES AND VALVES
The wheels are subject to significant stress, which is caused by the weight of the cyclist and any other
items you may be carrying, and the unevenness of the terrain over which the bike moves. This is why we
recommend that you inspect the wheels regularly, particularly to make sure that their crucial components
are not excessively worn and that the wheels turn smoothly. If you have any concerns you should contact
a specialised seller (servicing facility). After each accident check the wheel spokes to make sure that
there is no damage.

The front and rear wheels of most MTF bicycle models are equipped with easy-to-use quick-release
mechanisms, which simplify mounting and removal of the wheels.

1.
Release the lever of the quick-release mechanism, loosen it by
several turns and then insert the wheel into the fork.
2.
Tighten the regulating nut until you feel slight resistance.
3.
Close the lever of the quick-release mechanism so that the side
bearing the word CLOSE faces outwards and so that the lever is
parallel to the fork. You must use a certain amount of force to close
the quick-release mechanism. When closing the mechanism you
will feel more resistance as the lever is pushed closed the last third
of the way, not before.
4.
Check that the wheel is correctly fitted in the fork and centred (that
the rims and tyres of the wheel do not graze the brake shoes /
pads, or possibly the rear fork structure).
