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.
Three Stages of Control
By independently optimising 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.
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.

As with other aftermarket suspension offerings from Vorsprung, the Secus has a notable effect on performance. Even with the latest Fox 36 providing more mid stroke support than previous models, the Secus improved it even more and the lighter initial stroke and gentler final portion of travel overall made the fork more comfortable and capable on the trail.AJ Barlas, NSMB
The Secus’ impressive sensitivity takes the initial harshness off high-speed impacts so nicely it got me hyped up to ride harder and faster! Plowing through medium-sized bumps at high speeds, I found the repeated impacts easier on my arms and felt like my front wheel was finding traction in those rough patches better than before.Steve Fisher, Bikerumor.com
The Secus does what it says on the tin. It significantly improves tracking, predictability and reduces brake dive, but this inevitably comes with small downsides; chiefly it's less forgiving on large bumps. I also found that going up in travel was the best way of maintaining ride height while enjoying the full benefit of the soft-beginning stroke, which is something to consider. The benefits and trade-offs may vary with other forks, but with the RockShox Zeb I tested it's a good option for aggressive or stronger riders who are happy to take a bit more big-hit feedback in exchange for more predictability, support and ground-hugging grip.Seb Stott, Pinkbike
I think the biggest benefits of the Secus will be felt by people — like me — who care a lot about midstroke support and generally find themselves trying to eke as much as possible out of their forks without diminishing their performance in other areas. That said, I also truly don’t think that there are any performance downsides to the Secus compared to a stock fork, no matter how you prefer to set up your suspension. It’s a very clever, very impressive offering."
