- Created to optimize the setup of the fork
- Optimal ground adaptation
- Attenuation of the 'bobbing' during the ascent
- Progressiveness of the final part of the race is more gradual than a "solo air" fork, so the whole run is exploited more easily
- Slightly lower negative pressure
- "Plush" effect at high speeds
- Slightly lower positive chamber pressure at the same weight of the biker
- Air volume reduction equal to 70% of the positive room
- Any pressure increase related to friction overheating is compensated by the volume change of the polymer
- Behavior of the constant fork during prolonged use over time
