5 The functions of the most important
components
5�1 Stability – the frame
The woom ORIGINAL frame is made of lightweight, high-quality aluminium tubes. As such it
offers the necessary stability with minimum weight.
5�2 Front wheel attachment – the fork�
The fork connects the front wheel with the frame as well as additional components such as
the stem and front brake.
5�3 Steering – the handlebar
The position and shape of the handlebar help ensure a correct sitting posture. In addition
to the grips, the handlebar also accommodates other components (brake lever, shifter, bell,
reflector, etc.).
5�4 Shock absorption and grip – the tyres
The tyres must carry the weight of the wheel, the person cycling and any luggage. The heavier
the weight, the higher the air pressure should be. The permissible pressure range is indicated
on the tyres. See also Section 9.1 on page 48.
5�5 Stopping in time – the brakes
The woom ORIGINAL has two rim brakes; one on the front wheel and one on the rear wheel.
When braking, the brake pads press against the brake surfaces on the wheel rim to stop the
wheel. See also Section 7.1 on page 46.
5�6 Drive – the 8-speed gear
The cranks connect the pedals with the bottom bracket. The chainring connected to the right
crank transmits the driving force via the chain to the rear wheel. There are eight sprockets of
different sizes mounted on the rear wheel (together referred to as cassette). The rear derail-
leur is also located there. The woom ORIGINAL rear derailleur guides or shifts the chain over
the differently sized sprockets. This results in different transmissions of the applied force.
High transmission ratios are achieved when the chain lies on a small rear sprocket. Pedalling
is more difficult, but the bike travels further with one turn.
Lower transmission ratios are achieved when the chain lies on a large rear sprocket. Pedalling
is easier, but the bike travels a shorter distance with one turn.
