Secus Air Spring Upgrade -

For the first time, there is 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



Three Stages of Control

By independently optimizing the beginning, middle and end portions of the stroke, the Secus gives you the linear-to-progressive spring rate that coil springs and traditional air springs alike wish they had. 

Ride with confidence
