Inspection of the Bearings
Maintenance
Frequently check the bearings of the bicycle. Have a bicycle service shop lubricate the
bearings once a year or any time they do not pass the following tests:
Head Tube Bearings
The fork should turn freely and smoothly at all times. With the front wheel o the ground,
you should not be able to move the fork up, down, or side-to-side in the head tube.
Crank Bearings
The crank should turn freely and smoothly at all times and the front sprockets should not
be loose on the crank. You should not be able to move the pedal end of the crank from
side-to-side.
Wheel Bearings
Lift each end of the bicycle o the ground and slowly spin the raised wheel by hand. The
bearings are correctly adjusted if:
The wheel spins freely and easily.
The weight of the spoke reector, when you put it toward the front or rear of the
bicycle, causes the wheel to spin back and forth several times.
There is no side-to-side movement at the wheel rim when you push it to the side with
light force.
Suspension Frame (various models)
Adjustment: The bicycle may have an ad-
justable shock-absorbing suspension. You
can change the suspension, as you prefer,
for a softer or a rmer ride.
WARNING: Make sure there are at
least two threads showing
C
above the
Adjusting Nut
A
so the shock does not
come loose.
To change the suspension:
For a softer ride, turn the Adjusting Nut
A
clockwise so the Suspension Spring
B
is compressed less.
For a rmer ride, turn the Adjusting Nut
A
counter clockwise so the Suspension Spring
B
is compressed more.
