Quantum Zero
No Compromise
Quantum Zero is a range of monotube shock absorbers. No matter which vehicle or how many ways of adjustment, every Zero shock absorber shares the same basic architecture and many of the same components.
Gas Pressurized
Zero shock absorbers are gas pressurized. The gas and oil are kept separate using a floating piston. This ensures consistent performance with the shock absorber in any orientation.
Infinitely Adjustable
Zero shock absorbers are available with up to two ways of external damping adjustment—and all can be opened by a competent individual and re-valved or re-jetted internally.
Throwing Shapes
A range of pistons allow the shape of the damping curve to be easily tuned. Linear. Digressive. Find your winning formula.
Zero
The adjustable non-adjustable.
No external adjusters. No Compromises. A non-adjustable damper that is fully adjustable.
One.Zero
External adjustment. Simplified.
A single clicker knob makes damping adjustment quick and easy to understand.
Two.Zero
Two-way adjustment. At the turn of your wrist.
Two colour coded clicker knobs provide independent adjustment of compression and rebound damping.
