BICYCLE COMPONENTS
Wheels
Wheels should be centered in fork or dropouts. Whenever you hear any irregular noise
from the wheels or the brakes, the wheels should be checked and repaired. Wheels
should be checked regularly for spoke tightness and rim alignment. Wheels should
rotate smoothly without wobbling from side to side. Check the bearing play of the hubs
by lifting the bicycle and spinning the wheel. The wheel should continue to spin for
several turns and finally cease spinning. To check the play of the hubs, try to move the
rim from side to side between the forks. During this test, no substantial play should
exist. If you detect play or if the wheel is difficult to turn, the hub bearings must be
adjusted. Please contact a local bicycle dealer to have the hub bearings adjusted.
Rims
The rims must be smooth and without cracks, breaks or bulges.
Spokes
Check spoke tension regularly. Approximately the same tension should be applied to all
spokes. If there is minor loosening of the spokes, you may tighten the nipples, but it is
recommended that you take the bicycle to a bicycle mechanic. If you detect a loose
spoke or if the rim has a side play of more than 4mm (1/8 inch), immediately have the
wheel trued by a bicycle mechanic.
RIDING WITH LOOSE SPOKES MAY CAUSE THE WHEEL TO FAIL
Tires
Inflate your tires to the pressure of 40 PSI bike.
Every time you ride, make sure that the tires are inflated according to pressure indicated
on tire sidewall. Improper tire pressure will cause excessive wear, causing premature
replacement. Low tire pressure will also make riding more difficult. The tire should be
properly seated in the rim and the fitting of the tire bead and rim bead should be
checked. If the tube is pinched between the tire and the rim, it will fail when inflated.
Ensure that the tire is not cracked or unevenly worn. Check for bulges. Check that the
valve is straight in the rim. Irregular tires should be replaced immediately.
