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 brak-
ing 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 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.
seatpost:
If your seatpost has an over-center cam action
fastener for easy height adjustment, check that it is properly
adjusted and in the locked position.
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.
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 exten-
sions can cause you to lose control and fall. Unplugged
handlebars or extensions can cut you and cause serious
injury in an otherwise minor accident.
