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.
Dual chamber air spring cartridge. The patented design provides a near linear compression curve for a “coil-like” feel while maintaining infinite adjustability.
Easy Drop-In Installation
Half the price of a coil conversion
Coil like suppleness and mid-stroke support
Built in tunable progression or “bottom out resistance”
1/2 Lb Lighter than coil conversions and only 20 grams heavier than same amount of tokens or spacers
Maintains your fork’s air spring compatibility.

The Luftkappe offers more compliance, support, grip and control. By softening the initial stroke, the Luftkappe enhances sensitivity and enables higher air pressure for increased support in the middle and end of the stroke. Giving you less harshness and hand fatigue.
