Inspection
Brake levers should be checked for tightness at least every three months. They should be
set in a comfortable position within easy reach of the rider's hands. Brake levers should be
firmly affixed to the handlebar. The brake pads should be checked for correct positioning
and tightness before every ride, and the various bolts and nuts at least every three months.
Squeeze each brake lever to make sure they operate freely and that the brake pads press
hard enough on the rims to stop the bike. There should be about 1mm2mm clearance
between each pad and the rim when the brakes are not applied. The brake pads must be
properly centered for maximum contact with the rim. Replace the brake pads if they are over
worn (when the grooves or pattern can't be seen). The brake cable wires should be checked
for kinks, rust, broken strands, or frayed ends. The outer casing should also be checked for
kinks, stretched coils, and other damage. If the cables are damaged, they should be
replaced.
Cables and Cable Housing
Cables and housing are one of the most over-looked parts on the bicycle. The first indication
that your cables and housing need to be replaced is an increased amount of pressure
needed to operate the brakes or shifters. Before every ride, check that there are no kinks or
frays in the cables and housing. Also check that the housing is seated properly into each
cable stop on the bicycle. It is recommended that the cables and housing be replaced at
least every riding season to prolong the life of your bike.
WARNING:
Do not ride a bicycle that is not operating properly.
Hub Bearing
When checked, the hub bearings of either wheel will require adjustment if there is any play.
1.Check to make sure locknuts are tight.
2.To adjust, remove wheel from bicycle and loosen the locknut on one side of the hub while
holding the bearing cone with a flat open-end wrench.
3.Rotate the adjusting cone as needed to eliminate play.
4.Re-tighten the locknut while holding the adjusting cone in position.
5.Re-check that the wheel can turn freely without excessive play.
Wheel Inspection
It is 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:
Dirty or greasy rims can render your brakes ineffective. When cleaning, use
a clean rag and wash with soapy water, rinse and air dry. Don't ride while the wheels are still
wet. When lubricating your bicycle, do not get oil on the rim.
Straight wheels
Lift each wheel off the ground and spin them to see if they are straight and true. If wheels are
not straight, they will need to be adjusted. This is difficult and is best left to a bicycle
technician.
Broken or loose spokes
Check that all spokes are tight and that none are missing or damaged.
CAUTION:
Damaged spokes can cause serious injury.
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, adjustment is
required.
