Pedal cranks may become loose, therefore the correct positioning
of the crank should be checked on a regular basis. Hold both crank
arms with both hands and move the crank back and forth. If you
fi nd out that they wobble, this means there is some damage. Even
bottom brackets may wear out after a certain period of time. If you
hear a cracking noise in the bottom bracket, have the bottom bracket
repaired by a specialist or have it replaced.
4.10. Derailleur
For the woom bikes 4, 5, 6 we use a high-quality SRAM Sx4 GripShift rotational handle
as the gear shift. You can change gears with it. After some time of using it, an adjustment
might be necessary.
Derailleur
The woom bikes 4, 5, 6 use a high-quality derailleur, the
SRAM X4 Derailleur. Normally,
the setting of the derailleur has already been done before delivery.
If there are any problems with the gears due to an accident or another
occurrence, we’ll ask you to take the bike either to a bike store, or to
repair it yourself in case you are skilled enough to do some repairs
using the SRAM product manual.
4.11. Bicycle chain
The bike chain is subject to heavy strain,
and therefore has to have a certain tension.
The tension is ideal if the chain cannot be
pulled downwards in a way that is shown on
the fi rst photo. If there is a creaking in the
bottom bracket due to far too much tension,
tension can be adjusted by moving the rear
wheel horizontally.
