GEAR SHIFT SYSTEM
23.2
Operating the derailleur gear
• Operating element for the front derailleur: When shifting gears, the front derailleur
moves the chain to the required chain ring.
A small chain ring is recommended for ascending stretches of road while a larger chain
ring is recommended for even stretches of road.
• Operating element for the rear derailleur: When shifting gears, the rear derailleur
moves the chain to the required sprocket.

Checking the derailleur gear
• Check the derailleur gear components regularly to ensure they are functioning correctly
and to prevent unnecessary wear.
-
Check that the chain, chain rings, sprockets, front derailleur, rear derailleur and gear
cable are not damaged.
-
Check that the distance between the chain and rear derailleur to the rear wheel or
to the spokes is sufficient.
-
Check that the rear derailleur is in a vertical position in relation to the sprockets and
is not bent.
-
Check the chain tension: The chain should not sag. If you carefully push the rear
derailleur forwards (in the direction of the pedals), it should return to its original
position by itself when you release it.
-
Lift the rear part of the bike so that you can move the rear wheel and use the pedals
to set the rear wheel gently in motion.
-
Shift through all the gears: Shifting should be easy; there should be no blockages or
unusual noises.
• Contact your specialist dealer:
-
to replace any damaged or worn derailleur gear components and re-adjust the derail-
leur gear again afterwards.
-
to check the derailleur gear and adjust it if necessary if you notice any irregularities
during the check.
