Plug and play magic cartridge for mountain bike air forks, powered by activated carbon. Despite taking up space inside your fork, it increases its effective air volume, creating a plusher and linear feel. This first edition consists of a 3D printed shell containing our coated activated carbon recipe.

Activated carbon plug and play insert that installs like a token, but acts to increase the effective air volume of your fork, resulting in a more linear spring curve.

• Reduces air stiffness, for better small bump sensitivity, comfort and grip without compromising sag 
• Makes the spring force more linear, closer to a coil but with the adjustability and weight advantage of air
• Permits greater use of travel when charge pressure is unchanged  
• Initial suppleness drastically reduces chatter, lessening arm pump and fatigue
