HOW TO CHECK
WHEEL RIM WEAR
Check the condition of wheel rims wear
before every ride.
It is important to your safety, that, you also check the
surface wear of the wheel rims (in addition to brake
pad wear). This is the area of the wheel where the
brake pads contact the rim. Rims can wear out.
How Can You Check Rim Wear?
Some wheels have wear indicators built in. Some
indicators are depressions in the rim lower that the
surface where the pads touch. When the surface
reaches this depression the wheel is worn out. Other
indicators are visible markings or signs that are
exposed to view when the braking surface is worn out.
Consult the wheel manufacturer’s instructions/
manuals for information on how to check wear for
your specic wheels.
WARNING
Bicycle wheel rims are subject to wear and
damage. A worn-out or damaged wheel rim has
reached its maximum usable life and must be
replaced.
■ Riding on unusable “worn-out” or damaged
wheels can lead to braking or wheel failure.
■ Replace your wheel when they become worn-
out or damaged.
■ Do not ride your bike when the wheels are
damaged or worn-out.
■ Ask your Dealer for help with inspecting the
rim wear of your wheels.
You can be severely injured, paralyzed or
killed in an accident if you ignore this
message.

WARNING
Some road bikes are equipped with disc brakes.
Relative to conventional rim brakes, disc brakes
are less aected by water, do not wear or heat
the rims and therefore are more consistent. Disc
brakes also may be more powerful.
To minimize risk of injury or accidents:
■ Understand that road bikes have a relatively
small tire contact patch (part of the tire
that touches the road). In order to apply
the brakes safely and eectively, you may
need more or less braking force in dierent
situations. You need to take into account
various road and weather conditions that can
aect traction.
■ Disc brakes are excellent, but not some
kind of magic. Take some time riding
your new disc brake road bike in lower risk
circumstances to get used to the feel and
performance of the disc brakes and tires.
You can be severely injured, paralyzed
or killed in an accident if you ignore this
message.
