CHAPTER ONE
Guide to Safe On-and-Off Road Operation
5. If the lever is moved to the
CLOSED
position
with little or no resistance, clamping strength
is insufficient. Return the lever to the
OPEN
position, tighten the quick-release adjusting
nut further and close the lever, and again
test for resistance. For further information
on correct adjustment of the quick-release
tension, read Figure 1.12.
6. Orient the quick-release levers so they do
not interfere with any other bicycle part or
accessory part (such as rack or fenders), and
so obstacles in the path of the bicycle cannot
snag the levers (Figures 1.10-1.11).
7. Test that you have properly adjusted and
closed the quick-release. If the quick-release
fails any test, either repeat these adjustment
procedures, including these tests, or take your
bicycle to your Gary Fisher dealer for service.
Test for proper quick-release adjustment
• Pick up the bike, and sharply hit the top of the
tire (Figure 1.13). The wheel must not come
off, be loose, or move from side to side.
• Make sure the quick-release lever cannot be
rotated parallel to the wheel (Figure 1.14).
• When the quick-release is properly tightened,
and clamped by the lever in the closed position,
the clamping force is adequate to cause metal-
into-metal engagement (embossing) of the
dropout surfaces.
• See Figure 1.12.

If it requires more than 45 pounds (200
Newton) force to completely close the quick-
release lever, open the lever and slightly loosen
the quick-release adjusting nut.
If it requires less than 12 pounds (53.4
Newton) force to begin to open the lever from
the fully closed position, open the lever and
slightly tighten the quick-release adjusting nut.
Repeat the adjustment if necessary.
