Gears

WARNING
Never shift a derailleur onto the largest or the smallest sprocket if
the derailleur is not shifting smoothly. The derailleur may be out of
adjustment and the chain could jam, causing you to lose control and fall.
If you have difficulties with shifting, the problem could be
mechanical adjustment. See your dealer.
The gears are operated by controls on the handlebars (gear lever, twist
grips, ...). The gear shift allows you to adjust the gear of your bike and the
transmission to the current situation. On a straight level stretch a higher
gear is sensible to achieve and maintain a higher speed without having to
pedal too much.
As soon as you start going uphill a lower gear is beneficial, because it is
important to be able to climb the hill with little effort. Select the gears so
that your legs are always moving at a steady pace.
Derailleur
With this system the chain is lifted on to
a sprocket when changing gear. The
chain must continue moving so that the
teeth of the sprocket can engage with
the chain links easily and smoothly.
For a successful gear change you must
therefore keep pedaling forwards, never
backwards! – but at the same time
pedaling lightly and without force.
You should clean the pinions at regular intervals with a
neutral cleaner. Cleaning with a neutral cleaner and then
lubricating can effectively extend the life span of the
pinions and chain.
