Forks - Dynacraft SINGLE SPEED Owner's Manual

FORKS

There are two different types of forks that range in styles and
dimensions. One type is a rigid fork (figure 1) consisting of stationary
tubing with curved blades. The other type is a suspension fork
(figure 2) consisting of stanchion tubes riding on elastomers or
springs inside of a straight fork leg. This mechanism acts as a shock
absorber with a specified amount of travel that varies between
models. If service is needed on a suspension fork, consult a
professional bicycle repair technician.
CAUTION
Do not attempt to disassemble a suspension fork yourself.
Consult a professional bicycle repair technician.
Check the tightness of the headset and the fork. Rotate the fork
checking for smoothness. If it feels like the fork is binding, then an
adjustment will need to be made to the headset. Move the fork in a
push/pull manner checking for tightness. If any play is detected,
loosen the top nut (shown on page 87). Recheck the rotation and
tightness. If necessary, readjust until a smooth rotation is achieved
without backward or forward movement. If your bike is equipped
with a suspension fork, check that the fork compresses and
rebounds smoothly. To do this, place the fork dropouts against
the ground, push and release the handlebar. The fork will generally
compress 1 - 2 inches and rebound quickly. Most elastomer type
forks will gradually soften with use.
