Gear shift
6.1.4 Checking the derailleur gear system
f Check the derailleur gear system regularly to prevent
loss of function and unnecessary wear.
f Make sure that the chain, chain rings, sprockets
and rear derailleur are undamaged.
f Ensure that the chain and rear derailleur have
sufficient clearance from the rear wheel or
spokes.
f Make sure that the rear derailleur is
perpendicular to the sprockets and not bent.
f Check the chain tension: The chain must not sag.
If you carefully push the rear derailleur forwards
(towards the pedals), it should move back to its
original position by itself when you let go.
f Contact a bicycle dealer to:
f replace damaged or worn components of the
derailleur gear system and then have the
derailleur gear system readjusted.
f have the derailleur gear system checked and
adjusted if necessary.
6.2 Hub gear system
The shift mechanism of a hub gear system works in
the rear wheel hub (according to the principle of a
"planetary gear"). The rear wheel rotates more or less
than the sprocket itself per sprocket revolution,
depending on the set gear.
