Cycle Derailleur shifting system

5.5 Maintaining braking force
Diminished brake action in disc brakes due to the brake system overheating is known
as “fading”. When the temperature at the point of contact between the brake pads and
brake disc rises, e.g. due to continuous braking, the brake power drops.
x Avoid long periods of continuous braking.
x Allow the brake pads to cool down regularly.
x Do not use the cycle if the brake power is reduced due to warming.
x Only use the cycle again once full brake power is restored.
6 Derailleur shifting system
6.1 Basics
Usually all modern cycles have a gear shifting system installed; this depends on the
cycle model. Exceptions include children’s bikes, which may only have one gear
depending on the model.
The gear shifting system on a cycle consists of a variable gear unit and the
corresponding controls. As a result, the power provided by the rider is adapted to suit
the riding speed and route conditions.
A derailleur shifting system consists of 1 to 3 chainrings on the crankset and
6to12sprockets on the rear wheel (see “Illustr.: Components of a derailleur shifting
system”). Separate controls on the right and in some cases the left-hand side of the
handlebars are generally used to shift sprockets and chainrings
(see the “Derailleur shifting system / Operation” chapter).
Adjustments to the gear shifting system require expertise.
