rim wear indicator on the side of the wheel rim is an indication that the
wheel rim has reached its maximum usable life. Riding a wheel that is at the
end of its usable life can result in wheel failure, which can cause you to
loose control and fall.
Brakes:
Check the brakes for proper operation (see Sections 4.C).
Squeeze the brake levers. Are the brake quick-releases closed? All control
cables seated and securely engaged? If you have rim brakes, do the brake
pads contact the wheel rim squarely and make full contact with the rim? Do the
brakes begin to engage within an inch of brake lever movement? Can you apply
full braking force at the levers without having them touch the handlebar? If not,
your brakes need adjustment. Do not ride the bike until the brakes are properly
adjusted by a professional bicycle mechanic.
Wheel retention system:
Make sure the front and rear wheels are
correctly secured. See Section 4.A
Seat post:
If your seat post has an over-center cam action fastener for
easy height adjustment, check that it is properly adjusted and in the locked
position
.
See Section 4.B
.
Handlebar and saddle alignment:
Make sure the saddle and handlebar
stem are parallel to the bike’s center line and clamped tight enough so that you
can’t twist them out of alignment. See Sections 3.B and 3.C.
Handlebar ends:
Make sure the handlebar grips are secure and in good
condition. If not, have your dealer replace them. Make sure the handlebar ends
and extensions are plugged. If not, have your dealer plug them before you ride.
If the handlebars have bar end extensions, make sure they are clamped tight
enough so you can’t twist them.
WARNING: Loose or damaged handlebar grips or extensions can
cause you to lose control and fall. Unplugged handlebars or
extensions can cut you and cause serious injury in an otherwise
minor accident.
VERY IMPORTANT SAFETY NOTE:
Please also read and become thoroughly familiar with the important
information on the lifespan of your bicycle and its components in Appendix
B on Page 43.
D. First ride
When you buckle on your helmet and go for your first familiarization ride on
your new bicycle, be sure to pick a controlled environment, away from cars, other
cyclists, obstacles or other hazards. Ride to become familiar with the controls,
features and performance of your new bike.
Familiarize yourself with the braking action of the bike (see Section 4.C). Test
the brakes at slow speed, putting your weight toward the rear and gently applying
the brakes, rear brake first. Sudden or excessive application of the front brake
could pitch you over the handlebars. Applying brakes too hard can lock up a
wheel, which could cause you to lose control and fall. Skidding is an example of
what can happen when a wheel locks up.
If your bicycle has toeclips or clipless pedals, practice getting in and out of the
a wide variety of fastener sizes and shapes made in a variety of materials,
often differing by model and component, the correct tightening force or torque
cannot be generalized. To make sure that the many fasteners on your bicycle
are correctly tightened, refer to the Fastener Torque
Specifications
in Appendix
D of this manual or to the torque specifications in 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 you 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 or from your
dealer. 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 your dealer
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 you’re not sure, ask someone with experience
to check.
Tires & Wheels:
Make sure tires are correctly inflated (see Section
4.G.1). 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 tire
deflection. Compare what you see with how it looks when you know the tires are
correctly inflated; and adjust if necessary.
Tires in good shape? Spin each wheel slowly and look for cuts in the tread
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.
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.
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.
WARNING: Bicycle wheel rims are subject to wear. Ask your dealer
about wheel rim wear. Some wheel rims have a rim wear indicator
which becomes visible as the rim’s braking surface wears
.
