USHING
The high quality bushings in RockShox forks are designed to last many months of hard riding. Protective
boots, a clean fork, and timely greasing are the keys to high performance and long bushing life. However, like
all moving parts, bushings will eventually wear and need replacement. Increased fore and aft movement of
upper tubes in lower tubes (similar to a loose headset) and/or slow action, even after a fresh greasing, signal
the need to remove and replace the bushings.

Glossary of Terms

Bottoming Out – the condition when all suspension travel has been used up.
Compression Stroke – the "upward" motion of a fork which is moving in response to a bump impact.
Damping Force – the force required to move a shock absorber/damper (general oil) at any given speed.
Forged – a metal forming process which optimizes material structure using very large forces acting on a
die mold in which material to formed is placed.
Geometry – Descriptive term for the lengths and angles used in a bicycle design.
Head angle – Angle the steering axis leans back from vertical.
Negative Spring – Spring assembly that controls the top out and plushness of the fork.
Oil bath – oil reservoir system used for lubricating internal parts in the fork.
One piece – unitized lower leg assembly with both fork legs and fork brace cast as one piece.

Packing – when the wheel does not stay in contact with the ground
Preload – The amount either in pounds or inches, a spring is compressed when fitted to an extended
shock absorber.
Rebound – The extension or return direction of the shocks or suspension.
Sag – compression of the suspension caused by the rider's weight.
Spring rate – The amount of force required to deflect a spring a given distance.
Tapered – varying wall thickness of a tube. A design to optimize placement of material, allowing most
efficient design considering the loads.
.
Topping out – the position of the fork at the "top" of the travel, or when the fork is fully extended. The
action of complete extension of the fork.
