If sag is set properly, but you are using 

all of the fork’s travel prematurely, 

a reduction of volume should be 

performed. Cane Creek’s air volume 

reduction system allows any rider to 

achieve their desired “bottomless” 

feel without the need for additional 

materials. The system uses a static 

piston that is positioned on an indexed 

rod. This piston can be moved down the 

rod to decrease volume in the positive 

air chamber and increase the ramp of 

the air spring. Increased ramp = more 

progressive. 

1. 

 WARNING: If working on air 

spring be sure to remove all air 

from positive and negative air 

chambers.   

2.  Remove AIR top cap on left side leg 

and release air pressure from the 

top of the fork.  

 WARNING: Be sure all air 

pressure is released before the 

next step.Using a 30mm Wrench, 

turn air valve assembly counter-

clockwise.
