Trutune MTB Fork Insert for Rockshox or Fox

We love these! Works for any rider, but especially well for smaller, lighter riders. From our own testing, it transformed the Rockshox fork for our 12yr old (39kg) rider, allowing him to run a high air pressure, but more easily use the whole travel of the fork! We think it's a game-changer for lightweight kids, youth and small adult riders.

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
