Power Box Fin X1 V4 20cm Select SM040010020

Description:

The X1.V4 Power Box fin is a versatile performance fin engineered to work across any wave board setup — Quad, Thruster, Twinzer or Single — giving riders freedom to tune drive and maneuverability to their style and the conditions. Constructed from a reinforced composite for high strength and controlled flex, the fin delivers reliable power transfer from the board to the water while resisting impact and wear. Its refined foil and low‑drag profile help produce balanced thrust and quick response through turns, making it suited to both aggressive wave riding and responsive freeride sessions. The reinforced root and Power Box compatibility ensure a secure fit and excellent energy transfer under load. With multiple size grid and box options, the X1.V4 lets users assemble a custom fin configuration for optimal performance across a wide range of surf and wind conditions.
