a mechanical device using confined air to absorb the shock of motion

High pressure air reservoir used in a suspension fork or shock. Generally considered to be lighter, but not as plush as coil springs.

A flexible air-inflated chamber in which the air pressure is controlled and varied to support the load and absorb road shocks; formerly called air bag.

A manually adjustable air spring that is incorporated into each rear shock absorber. The air spring consists of a flexible rubber cylinder which seals the outside of the upper and lower halves of the shock absorber.

See pneumatic spring.
