D. Which gear should I be in?
The combination of largest rear and smallest front gears
(Figure 4.14) 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
not to use either the "smallest to smallest" or "largest to
largest" gear combinations because they may cause
unacceptable stress on the drive train. Learn to anticipate
the need to shift, and shift to a lower gear before the hill
gets too steep. If you have difficulties with shifting, the
problem could be mechanical adjustment. See your dealer
for help.
E. What if it won't shift gears?
If moving the shift control one click repeatedly fails to
result in a smooth shift to the next gear chances are that
the mechanism is out of adjustment. Take the bike to your
dealer to have it adjusted.
Avoid these extreme angles of the chain
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.
