Anti-Bottoming System Variations

Hydraulic anti-bottoming system prevents fork from harsh metal to metal clunk. Our ABS provides a ramp-up of resistance to cushion the end of travel. Fork oil is forced through a tight tolerance concentric tapered piston and ring area slowing the end of stoke of the stanchion tube or cartridge rod.

Fox 36, Lyrik, Yari, Pike and Revelation open bath Cartridge ABS

 

Shown above and below is the movement of the open bath cartridge oil lock ring as it reaches the bottom of the stroke, it is also adjustable in 3 mm increments to reduce the affect if desired. This allows you to add only the amount of bottoming resistance needed. All cartridge rods have multiple grooves to select the desired oil lock ring position.

 

For those debating on the ABS vs FvAT/HSB here is our recomendation

The abs is not normally needed unless you want to create a very linear feel by converting to coil or modifying the air side to be more linear (because most air forks are very progressive for the last 10 mm and act like a air bump stop anyways). The FvAT/HSB is needed if you do varying types of riding such as park groomed trails or jump lines which need a firm compression feel, and backside natural rocky and rooty trails need very soft high speed compression. This will force us to compromise your set up somewhere in between the two valving options. If we valve it for the park jump lines we can then use the FvAT/HSB system to create a blow-off system to prevent the harsh feel on the high speed rocks, roots and ledge bumps and retain the firmer valving for jump lines and groomed park trails.
