- Activated carbon increases the effective air volume in air forks for a more linear, plush feel - it's like having a coil spring but without the added weight- A fork with the insert can be compressed more than one without tokens (seriously)- Provides better small bump sensitivity and end-of-stroke absorption- Allows running higher pressures without the associated harshness- Enables lighter riders to make full use of their suspension travel range- Activated charcoal is a highly porous form of carbon which allows air to cling to the surfaces and become more compressible. The same technology has been in use in automotive and acoustic applications for over a decade- Two variants: Standard has a more linear spring curve, Short has a more progressive spring rate (variant's are optimized for fork model)
