Adjusting the derailleurs
Front derailleur: adjusting the lowest gear
Place the chain on the largest sprocket at the back and the
smallest chainwheel at the front. Turn the adjusting screw (A) in
such a way that the play between the inside of the chain guide
and the chain is no more than half a millimetre (fig. 65).
Front derailleur: adjusting the highest gear
Place the chain on the smallest sprocket at the back and the
largest chainwheel at the front. Turn the adjusting screw (B) in
such a way that the play between the inside of the chain guide
and the chain is no more than half a millimetre (fig. 65).
Front derailleur: adjusting the intermediate gear
Place the chain on the largest sprocket at the back and the
middle chainwheel at the front. Adjustment for the intermediate
gear is made with the adjusting barrel on the cable where it
emerges from the front gear shifter on the handlebar. Adjust so
as to set the play between the inside of the chain guide and the
chain to half a millimetre (fig. 65). Adjusting the front derailleur
with spcm unit is done as follows: align both markers beneath
the spcm unit when the shifter is in position “1” (fig. 66).
Rear derailleur: adjusting the highest gear
To adjust the highest gear, turn adjusting screw (A). Make sure
that the chain is on the outer sprocket and turn the adjusting
screw in such a way that the guide wheel, looking from the rear
of the bicycle, sits directly under this sprocket (fig. 67).
Rear derailleur: adjusting the lowest gear
To adjust the lowest gear, turn adjusting screw (B). Make sure that
the chain is on the inner sprocket and turn the adjusting screw
in such a way that the guide wheel, looking from the rear of the
bicycle, sits directly under this sprocket. Now check second gear.
If the chain is running against an adjacent sprocket, this can be
adjusted using the cable adjusting screw (C). In some models the
adjusting screws are in another position on the derailleur. Making
adjustments is done in the same way as described above (fig. 67).
Shimano Nexave rear derailleur: adjusting the lowest gear
Place the chain on the largest sprocket at the back. Turn the
adjusting screw (A) in such a way that the guide wheel, looking
from the rear of the bicycle, sits directly under the largest
chainwheel (fig. 68).
Shimano Nexave rear derailleur: adjusting the highest gear
Place the chain on the smallest sprocket at the back. Turn the
adjusting screw (B) in such a way that the guide wheel, looking
from the rear of the bicycle, sits directly under the smallest
chainwheel (fig. 68).
Note: the chain should move in as straight a line as possible. This
means that, when shifting, some combinations serve no purpose and
will lead to unnecessary wear on the chain and chainwheels. If the
chain is on the smallest chainwheel at the front, then prevent it from
being positioned on the two smallest sprockets at the back. If the
chain is on the largest chainwheel at the front, then prevent it from
being positioned on the two largest sprockets at the back. It’s also
advised not to combine the middle chainwheel at the front with the
smallest or largest rear sprockets. Therefore the red positions in fig. 69
are
not advisable.
