c. Shifting the Front Derailleur:
The front derailleur, which is controlled by the left
shifter, shifts the chain between the larger and
smaller chainrings. Shifting the chain onto a
smaller chainring makes pedaling easier (a
downshift). Shifting to a larger chainring makes
pedaling harder (an upshift).
d. Which Gear Should I Be In?
The combination of largest rear and smallest front
gears (fig. 19) is for the steepest hills. The
smallest rear and largest front combination is for
the greatest speed. It is not necessary to shift
gears in sequence. Instead, find the "starting
gear" which is right for your level of ability – a
gear which is hard enough for quick acceleration
but easy enough to let you start from a stop
without wobbling – and experiment with upshifting
and downshifting to get a feel for the different
gear combinations. At first, practice shifting where
there are no obstacles, hazards or other traffic,
until you've built up your confidence. Learn to
anticipate the need to shift, and shift to a lower
gear before the hill gets too steep or you have to
stop at a road junction. If you have difficulties
with shifting, the problem could be mechanical
adjustment, see your local 13 dealer for help.
CAUTION: Never ride with the gears
set to the combination of either the
largest chainring and the largest rear
sprocket or the smallest chainring and
the smallest rear sprocket. These gear
combinations cause the chain to run at
extreme angles, shift to another chainring
and another rear sprocket to achieve a
similar gear ratio.
e. Adjustment
WARNING: Set up and adjustment of
derailleur gears requires specialist
knowledge. Do not begin any adjustments or
service on your bicycle until you have learned
from your local 13 dealer how to properly
complete them. Improper adjustment or
service may result in damage to the bicycle or
in an accident, which can cause serious injury
or death.
See the gear manufacturer's instructions for
operation and care of your gears. If you do
not have the manufacturer's instructions, see
your local 13 dealer or contact the gear
manufacturer.

WARNING: Never shift a derailleur
onto the largest or the smallest
sprocket if the derailleur is not shifting
smoothly. The derailleur may be out of
adjustment and the chain could jam,
causing you to lose control and fall.
