CHAPTER THREE
Inspection, Adjustment & Lubrication
Introduction
The wheels (Figure 3.8.1) of a bicycle allow the bike to
roll down the road or trail smoothly, so their integrity
and structural soundness is crucial. In addition, their
relationship to the performance of your brakes is of great
importance. These instructions explain how to inspect, adjust,
and lubricate the wheels of a bicycle.
Inspection
The best maintenance of a wheel is preventative
maintenance. Be aware of the things that can go
wrong, so you can stop trouble before it happens.
Before every ride
check that your quick-release
hubs are in their
CLOSED
(locked) position, or
that your wheel axle nuts are tight. For further
information on adjusting quick-release hubs, see
the
Adjustment
section, or consult your Gary
Fisher dealer. Check that the wheels are straight
and round by spinning them. If the rim (Figure
3.8.1) does not spin evenly, have your wheel
trued (straightened) by your Gary Fisher dealer.
Make sure your tires are inflated to the pressure
indicated on the tire sidewalls. Use a gauge and a bicycle pump
whenever possible. Avoid filling your tires at gas stations.
Because of the greater pressure and volume of air their pumps
release, blowouts are very possible. Inspect your tires for wear
and any other damage. If a tire has any cuts or separations
which go through the tire, making any part of the inner tube
visible, or if any part of the tire casing shows through the tire
tread (running surface) or knobs are worn or missing, replace
the tire. Make sure your rims are clean. Dirty or greasy rims
render your brakes ineffective. Wipe your rims with a clean rag
or wash them with soap and water, rinse, and let them air dry.
Every week
make sure there are no loose, damaged, or
broken spokes. If a wheel is not in good condition, both the
effectiveness of the brakes and the strength of the wheel are
greatly reduced.

WARNING
An improperly adjusted hub, where there is movement
between the hub and axle, can cause you to lose control and
fall. Inspect the hubs thoroughly before every ride, and do
not ride the bicycle until any problem has been corrected.
