Infinite Rate Tune (IRT) is a two-stage air spring configuration that allows for advanced spring rate tuning by independently adjusting air pressures in the beginning, mid and end strokes. The IRT secondary positive air spring affects only the middle to end stroke of the fork. This allows the primary air spring to be set to lower pressures for improved small bump sensitivity while maintaining independently adjustable mid-stroke support and end-stroke ramp-up.

Incremental Volume Adjust (IVA) modifies the volume in the positive air chamber with a set of self-contained spacers which dictate the fixed position of the IVA piston. This self-contained volume reduction system allows greater ramp-up change than conventional adjustment systems without the need for additional parts.

Identical performance to Dorado Air, with high strength steel shaft. The Expert Air spring is derived from our Dorado Air and offers equal performance at a lower price point with only a slight increase in weight. The system features a unique balancing valve that equalizes the positive and negative air chambers during the air fill process. This gives that spring rate a consistent feel without any flat or dead spots in the stroke, along with giving riders of different weights, the same initial stroke feel.  

The Dorado Air is our lightest weight air spring technology designed for the most demanding riders. The system contains a unique balancing valve that equalizes the positive and negative air chambers during the air fill process. This gives the spring rate a consistent feel without any flat or dead spots in the stroke, along with giving riders of different weights the same initial stroke feel.

Travel-Stabilization air spring technology uses a hybrid coil and rubber top-out spring system to maintain consistent ride height regardless of set-up pressure.  It is a very simple, highly reliable and time proven package that is easily tuned for multiple rider weights and riding styles. 

Isolation Air Spring (ISO) technology is an evolution of the TS Air system, using a rubber isolator between the compression rod and the piston to reduce high frequency, low amplitude inputs, thereby improving small bump compliance. It is a low friction, easily tuned air system that can be adapted to a variety of riding disciplines. It uses a coil negative spring for increased simplicity with a positive air chamber which is easily tuned for rider weight and style.
