Wheels
Wheel inspection:
The wheels of the bicycle should be kept in top
condition. Properly maintaining your bicycle’s wheels
ensures good braking performance and stability when
riding. Be aware of the following potential issues:
• Dirty or greasy rims
CAUTION: Dirt and/or grease can render your brakes
ineffective. Do not clean rims with oily or greasy materi-
als. When cleaning, use a clean rag or wash with soapy
water, and then rinse and air dry. Avoid riding when the
rims are wet. When lubricating your bicycle, don’t get
oil on the rim surfaces.
• Cracked or thinning rims
Traditional rim brake systems work by creating friction
between the rim and the brake pad when the rider
applies the brakes. This friction, plus the introduction of
dirt, grease, sand and other contaminants between the
rim and brake pad, will eventually cause the outer wall
of the rim (braking surface) to wear thin.
WARNING: In extreme conditions, the thin outer wall
can crack and fail, resulting in possible injury to the rid-
er. Inspect the outer walls of the rims regularly. Contact
a professional bicycle mechanic if cracks or other dam-
ages are found.
• Wheels not straight
Lift each wheel off the ground and spin them to see if
they are crooked or out of alignment. If the wheels are
