Maxima Plush Fluid
Developed with the world's fastest racers, on the world's toughest circuits. Maxima Plush Fluid is designed to protect from suspension wear, reduce friction, and silence damper noise while maintaining a consistent feel in all temperatures.
Everyone loves a good collaboration, which is why we’ve been working with SKF, the world’s highest-performance seal manufacturer, for over 5 years. Together we’ll provide ultra-low friction wiper seals, less fatigue, and unmatched suspension feel, all while keeping the dirt where it belongs- because no one wants dirt in there.
Low amplitude, vibration reducing material pucks... but we like to call them ButterCups. ButterCups block 20% of unwanted “trail chatter” before it reaches your hands. The gold housings on the end of the damper and air spring hold two rubber pucks that absorb the high frequency vibrations before they travel through the fork and into the handlebar. ButterCups reduce overall hand and arm fatigue and will leave you feeling fresh with more control over the trail.
DebonAir+ is built to strike the perfect balance of what riders really want: butter-like small bump feel, increased support throughout the travel, and higher overall ride height for more confidence when things get steep.
Scrap everything and start from scratch. It took a fresh set of eyes to produce what became the Charger 3 damper. Let’s see what we can do, where we can go. The result gives way to a new era of riding, where the decision between adding more damping and sacrificing your hands to a harsh ride doesn’t exist.
