32.2 Operating the derailleur system
Operating element for the front derailleur:
When shifting gears, the front derailleur shifts the chain to the required chain ring.
A small chain ring is recommended when riding uphill, while a larger chain ring is recom-
mended for even stretches of road or downhill slopes.
Operating element for the rear derailleur:
When shifting gears, the rear derailleur shifts the chain to the required sprocket.
˃ Chap. 32.1 "Method of operation" on page 47
.
Operation:
• Always select the most suitable gear and maintain a pedal frequency of 60 to 100 rpm.
• Always start off in a low gear.
• As soon as the pedal frequency becomes too high, shift up a gear.
• As soon as the pedal frequency becomes too low, shift down a gear.
32.3 Checking the derailleur system
• Check the derailleur components regularly to ensure that they are functioning correctly
and to prevent unnecessary wear.
-
Make sure that the chain, chain rings, sprockets, front derailleur, rear derailleur and
gear cables are undamaged.
-
Make sure that the chain and rear derailleur are far enough away from the rear wheel
or the spokes.
-
Make sure that the rear derailleur is positioned vertically in relation to the sprockets
and is not bent.
-
Check the chain tension: The chain should not sag. If you push the rear derailleur
forwards carefully (in the direction of the pedals), it should return to its original posi-
tion automatically when released.
-
Lift the rear part of the bicycle so that you can move the rear wheel and turn 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 system components and then have the
derailleur system adjusted again.
-
have the derailleur system checked and adjusted, if you notice any irregularities
during the check.
