Tires & Wheels
 Make sure tires are correctly inflated
(see "Tires" on page 39). 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 quali-
fied bike shop to have the wheel trued.
Wheels must be true for rim brakes to
work effectively. Wheel truing is a skill
which requires special tools and expe-
rience. Do not attempt to true a wheel
unless you have the knowledge, expe-
rience 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 sur-
face. Check to make sure that any rim
wear indicator marking is not visible at
any point on the wheel rim.
Bicycle wheel rims are subject to wear.
Ask your dealer about wheel rim wear.
Some wheel rims have a rim wear indi-
cator 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 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 lose control and fall.

Brakes

 Check the brakes for proper operation
(see "Brakes" on page 30). Squeeze
the brake levers. Are the brake quick-re-
leases 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 con-
tact 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 "Wheels" on
page 24.

Seatpost

 If your seatpost has an over-center cam
action fastener for easy height adjust-
ment, check that it is properly adjusted
and in the locked position. See "Seat-
post cam action clamp" on page 29.
