EVOL Air Chamber

Extra Volume

The infinitely adjustable pressure setting in the extra volume (EVOL) air chamber regulates spring rate in the final portion of the stroke and controls the bottom-out characteristics of the shock.

Increasing air pressure in the EVOL air chamber will give a more progressive spring curve to protect against harsh bottom-outs. Decreasing air pressure will provide a more linear curve to maximize usable travel.

When combined with the infinite adjustability of the main air spring, the EVOL air chamber allows the shock's spring curve to be tuned for any conceivable rider weight and/or terrain condition. The pressure in the EVOL air chamber is adjusted to control the bottom-out characteristics of the shock. Adjusting this pressure is similar to changing the main spring on a coil over shock.
