CHAPTER ONE
Guide to Safe On-and-Off Road Operation
Avoid shimmy or front-wheel wobble.
In very rare cases some riders, such as heavier riders on
larger bikes, may experience a “shimmy” or “harmonic oscilla-
tion” or “frame vibration” at certain speeds. Experts disagree
on what can cause a shimmy, but some believe it may be caused
by a loose headset, improper spoke tension, or frame alignment.
Riding “no-hands,” or front wheel impact, are among other
possible causes. If you believe you are experiencing a shimmy,
slow down immediately and take your bicycle directly to a Gary
Fisher dealer for inspection and repair.
Make sure accessories are compatible and safe.
To make your bicycle more personally useful, you may
choose to change parts or add accessories. Not all accessories
are compatible or safe. If you are unsure whether a part is
appropriate or safe, consult your Gary Fisher dealer.
Prevent contact of the toe-clip and front wheel.
When riding slowly, do not pedal if the handlebar
is turned. Modern, high-performance bicycles use
a short-wheelbase design, with the front wheel
close to the pedals. It may be possible at very slow
speeds when the handlebar is turned for your foot
or toe-clips to contact the front wheel, or fender
(Figure 1.2). At normal riding speeds the handlebar
does not turn enough for this to occur.
WARNING
A shimmy, or steering wobble, can cause you to lose control and
fall. If you experience a shimmy, slow down immediately. Take
your bicycle to your Fisher dealer for inspection and repair.

WARNING
Contact between your foot or toe-clip and the front wheel or
fender can cause you to lose control and fall. Avoid pedaling
when turning slowly.
CAUTION
Improper components or improper assembly can place unknown
stress on your bike or components. Stress can lead to failure,
which can cause you to lose control and fall. Before adding or
changing any part of your bike, consult your Gary Fisher dealer.
