Introduction
The wheels allow your bike to roll down the road smoothly so the
integrity of your bicycle wheels is crucial. Their structural soundness
and their relationship to the performance of your brakes are of great
importance.
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.
Inspection
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 Fisher dealer.
Before installing tires, make sure a rim strip is in place which completely covers the rim
web (wall to wall) so that all spoke holes are completely covered.
Check that the wheels are straight and round by spinning them. If the rim does not
spin evenly, have your wheel trued by your 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 that 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.
Every month, check that both hub bearings are properly adjusted. Lift the front end of
the bicycle off the ground with one hand and attempt to move the rim laterally, left to
right. Look, feel, and listen for any looseness in the hub bearings. Spin the wheel, and
listen for any grinding or other unusual noises. If the hub feels loose or makes any noise,
the hub needs an adjustment. Repeat these procedures for the rear wheel.
Every month, check your rims for wear. On adult-size bicycles there are wear indicators
in the braking surface, either a continous indented band or several small spherical
indentations at even intervals around the rim. If the braking surface has worn so that any
part of these indicators is no longer visible, have your dealer replace the rim.

Spokes
If there is movement between the axle and the hub, or you suspect
the hub may need an adjustment, do not ride your bicycle. Take
your bicycle to your Fisher dealer for service.
Make sure the rim strip covers all of the spoke holes or spoke
heads. If they are exposed they may puncture the inner tube and
may cause loss of control resulting in personal injury.
