CHAPTER ONE
Guide to Safe On-and-Off Road Operation
Threaded axle-nut wheel retention
If your bicycle is equipped with threaded axle-
nuts instead of quick-release mechanisms, make
sure the axle nuts are tightened correctly:
• Front wheel: 180-240 lb•in (20.3-27.1 Nm)
• Rear wheel: 240-300 lb•in (27.1-33.9 Nm)
• Rear wheel: 240-300 lb•in (27.1-33.9 Nm)
For each wheel, test to ensure that you have
properly tightened the axle-nuts. If the axle-
nuts fail the test, either repeat these procedures,
including these tests, or take your bicycle to your
Gary Fisher dealer for service.
Before Every Ride: Check Your Bike
WARNING
A wheel axle-nut that is not properly tightened may allow the
wheel to be loose or come off unexpectedly, causing you to
lose control and fall. Make sure the axle-nuts are tightened
properly before riding the bike.

Test for proper axle-nut 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.
Redundant retention washers
For the front wheel of children's bikes and BMX bikes with
axle nuts, a special toothed washer must be in place on both
sides of the hub for correct wheel retention. The toothed washer
is placed on the outside of the fork tip with the tooth in the
corresponding hole in the fork tip (Figure 1.15).
