Technologies:
Torque Caps
Torque Caps strengthen the connection between hub and fork with a larger contact surface. This creates a stiffer interface for more responsive steering and better control – so you can focus on the trail.
SKF seals
For over 5 years we’ve been working with SKF, the world’s leading seal manufacturer, to deliver ultra-low friction wiper seals with less fatigue and better suspension feel – while keeping the dirt out.
ButterCups
Low-frequency vibration dampers – we call them ButterCups. They absorb up to 20% of trail chatter before it reaches your hands. The gold capsules on the damper and air spring contain rubber pucks that reduce high-frequency vibrations before they transfer through the fork to the handlebars. The result: less hand fatigue and more control.
DebonAir+
DebonAir+ is designed to strike the perfect balance between small bump sensitivity, full travel support, and higher ride height for more confidence on steep terrain.
Maxima Plush Dynamic Suspension Lube
This oil reduces friction, extends service life, and improves suspension performance – over and over again.
