There are two different types of forks that vary in styles and dimensions.
One type is a more rigid fork (Picture at top) consisting of stationary tubing
with curved blades. The other type is a suspension fork (Picture at bottom)
consisting of inner stanchion tubes riding on the springs inside of a straight
outer fork leg. This mechanism acts as a shock absorber with a specified
amount of travel that varies between models.
Do not attempt to disassemble a suspension fork yourself. Consult your
local dealer for assistance.
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 handle- bar. The fork will generally
compress 1-2” and rebound quickly. Most elastomer type forks will
gradually soften with use.
