Original Cannondale 2Spring air piston assembly for Lefty 1.0 forks - both hybrid and booted - with PBR and XLR dampers.
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. It is wise to replace the air volume seals with our 100 hour service kit, part number 100HR.3210, when installing this kit.
