The Knuckles are the agile virtuosos of the lineup: two shapes in one box, tight tolerances, and a juicy bounce that knows exactly what your feet are asking for. Quick edge-to-edge transitions, precise control, and enough rebound to keep every turn lively.
In the standard configuration, the insert barrel rides on the bottom (board side): its small “step” fills the gap between the kingpin and the hole of the hanger, reducing play in the assembly for a more precise response. The gumdrop rides on top (road side), a smooth and subtle blend between a barrel and the traditional cone, with a rounded edge for ultra-smooth turn initiation and improved interface with the washers. Both are poured in our Randy Thane formula and offered in soft (orange) and medium (purple).
The Knuckles fit most reverse-kingpin longboard trucks, including Paris V2 and V3, Bear, Randal, Carver, Gullwing, Tracker, Caliber, Atlas, Bolzen, Aera, Rogue, PNL, and Ronin. They are not intended for traditional-kingpin street trucks; please check the measurements and compare with your current bushings before ordering.
