For the first time, we created an air spring with a truly better spring rate, everywhere in the travel, than a coil. The Secus upgrade delivers the first and only air spring system to really come indistinguishably close to the linear spring rate of a coil fork for the entire first 2/3rds of its travel, with the advantage of a gentle end stroke progression to prevent bottoming without the “wall of force” harshness that excessively progressive springs create.

Secus Advantages:

An enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance (yes, even compared to the Luftkappe)

Proprietary Midstroke Support Valve improves predictability and support beyond the sag point

Reduced lower leg pneumatic ramp means better scalability of the air spring, particularly for light riders who previously struggled to use full travel

Plush and predictable like a coil, bottomless like an air spring

Allows full use of travel in both directions – fully extends to topout without any quibbles (including on Debonair B1 air springs) and fully compresses without excessive ramp

Allows more lower leg bath oil to be used for superior lubrication

Considerably lighter than coil conversions – adds approximately 130g

Simple setup – inflate fork, bounce on it a few times, press MSV charge button, go ride

Compatible with OEM volume spacers for end-stroke progression adjustment

Compatible with other aftermarket top-cap systems such as DSD Runt and MRP Ramp Control

Lower compression ratios mean a more consistent spring rate

Transferrable between any Secus-compatible forks with only a footstud to change at most

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.
