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.
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,
adjust the bearing cup, and retighten the top nut. 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” and rebound quickly. Most elastomer type forks will gradually soften with
use.
