Cycle Derailleur shifting system
59
To shift gears smoothly, it is important that
the front and rear derailleurs are precisely
adjusted (see “Illustr.: Components of a
derailleur shifting system”).
x If the derailleur shifting system does
not function or makes a noise when
operated, have the system adjusted by
your dealer.
6.2.1 Adjusting the rear derailleur
To keep the chain and rear derailleur out of
the spokes and prevent the chain falling off
the smallest sprocket, the stop screws
(L and H) limit the range through which the
rear derailleur can pivot (see “Illustr.: Diagram
of a rear derailleur”).
L stands for “low gear”.
H stands for “high gear”.
To adjust the rear derailleur, follow these
steps:
1. Shift the chain onto the largest chainring
and the smallest sprocket at the rear
derailleur.
2. Turn the H stop screw until the guide
pulley is exactly underneath the smallest
sprocket.
3. Pull the shift cable taut and fix it in place using the cable tensioning screw on the
chain stays (see “Illustr.: Adjusting the rear derailleur”).
4. Shift the chain onto the smallest chainring and the largest sprocket.
