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.
