Optimizing
the start, middle, and end segments of the stroke, the Secus provides a
spring rate that combines linearity and progression, surpassing the
capabilities of coil springs and traditional air springs.

Initial stroke - enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance
Midstroke -
where traditional air spring rates drop off in the midstroke, our
proprietary Midstroke Support Valve technology boosts the midstroke
spring rate to maintain linearity, for support, predictability, ride
height and compliance
End stroke - enlarged lower
leg volume reduces overall progression even at higher pressures and
allows for a wider range of end-stroke ramp options to be utilised with
standard fork volume spacers.
