Product Question?

The Vorsprung Secus Fork Air Spring Upgrade Kit is an external air can that helps create more negative air space, creating a truly better spring rate for compatible air forks. Check out our blog article where we review the secus and go into detail about how the Secus feels & works.

**Please Make sure to let us know the exact fork you have.**

Compatible with Fox A1, Fox A2, Fox A3 air springs & RockShox A2. If you have Rockshox A3 please contact us.

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