Original Cannondale 2Spring air piston assembly for Supermax 2.0 and Olaf forks.

The 2Spring air piston replaces the older SoloAir piston and is an exact fit replacement. This is a performance upgrade to the SoloAir as well in addition to reducing the risk of broken wave springs in some older air piston designs.

Kit includes one 2Spring air piston kit and thread lock compound.

Kit does not include upper air volume assembly.
