Additional Information
cont’d
the instructions provided by the manufacturer of the component in question. Correctly
tightening a fastener requires a calibrated torque wrench. A professional bicycle
mechanic with a torque wrench should torque the fasteners on your bicycle. If you
choose to work on your own bicycle, you must use a torque wrench and the correct
tightening torque specifications from the bicycle or component manufacturer. If you
need to make an adjustment at home or in the field, we urge you to exercise care, and
to have the fasteners you worked on checked by a accredited bicycle mechanic as
soon as possible.
WARNING:
Correct tightening force on fasteners—nuts, bolts, screws—on your
bicycle is important. Too little force, and the fastener may not hold securely. Too
much force, and the fastener can strip threads, stretch, deform or break. Either way,
incorrect tightening force can result in component failure, which can cause you to loose
control and fall.
Make sure nothing is loose. Lift the front wheel off the ground by two or three inches,
then let it bounce on the ground. Anything sound, feel or look loose? Do a visual and
tactile inspection of the whole bike. Any loose parts or accessories? If so, secure
them. If not sure, ask someone with experience to check
Tires & Wheels: Make sure tires are correctly inflated. Check by putting one hand on
the saddle one on the intersection of the handlebars and stem, then bouncing your
weight on the bike while looking at the tire deflection. Compare what you see with
how it looks when you know the tires are correctly inflated; adjust if necessary.
Tires in good shape? Spin each wheel slowly and look for cuts in the thread and
sidewall. Replace damaged tires before riding the bike.
Wheels true? Spin each wheel and check for brake clearance and side-to-side wobble.
If a wheel wobbles side to side even slightly, or rubs against or hits the brake pads,
take the bike to a qualified bike shop to have the wheel trued.
Wheel rims clean and undamaged? Make sure the rims are clean and undamaged at
the tire bead and, if you have rim brakes, along the braking surface. Check to make
sure that any rim wear indicator marking is not visible at any point on the wheel rim.
CAUTION:
Wheels must be true for rim brakes to work effectively. Wheel trueing
is a skill which requires special tools and experience. Do not attempt to true a
wheel unless you have the knowledge, experience and tools needed to do the job
correctly.
WARNING:
Bicycle wheel rims are subject to wear. Ask a certified bike mechanic
about wheel rim wear. Some wheel rims have a rim wear indicator which
becomes visible as the rim’s braking surface wears. A visible rim wear indicator on the
side of the wheel rim is an indication that the end of its usable life can result in wheel
failure, which can cause you to loose control and fall
