WHEELS AND TIRES
Wheel Inspection
It is most important that wheels are kept in top condition. Properly maintaining your bicycle's wheels will help braking
performance and stability when riding. Be aware of the following potential problems:
•Dirty or greasy rims:
Caution: These can render your brakes ineffective. Do not clean them with oily or greasy materials. When
cleaning, use a clean rag or wash with soapy water, rinse and air dry. Don't ride while they're wet.
When lubricating your bicycle, don't get oil on the rim braking surfaces.
•Wheels not straight:
Lift each wheel off the ground and spin them to see if they are crooked or out of round. If wheels are not straight, they
will need to be adjusted. This is quite difficult and is best left to a bicycle specialist.
•Broken or loose spokes:
Check that all spokes are tight and that none are missing or damaged.
Caution: Such damage can result in severe instability and possibly an accident if not corrected.
Again, spoke repairs are best handled by a specialist.
•Loose hub bearings:
Lift each wheel off the ground and try to move the wheel from side to side.
Caution: If there is movement between the axle and the hub, do not ride the bicycle. Adjustment is required.
•Axle nuts:
Check that these are tight before each ride.
•Quick release:
Check that these are set to the closed position and are properly tensioned before each ride.
Caution: Maintain the closed position and the correct adjustment. Failure to do so may result in serious injury.
