US Box Fin X1 V4 17cm Select SM040150017

Description: The Select X1.V4 17cm US Box fin is a versatile wave-board fin engineered to work across a wide range of board configurations — Quad, Thruster, Twinzer or Single — allowing riders to dial in their preferred setup for different conditions and riding styles. Built from durable composite materials, the X1.V4 combines strength and lightness to deliver consistent tracking and reliable performance in demanding wave environments. Its refined foil and base geometry reduce drag while providing predictable bite and drive through turns, making it suitable for both spirited shortboard surfing and performance wave riding. The fin’s size grid and US Box compatibility make swapping and configuring fin sets quick and straightforward, so riders can experiment with balance, hold and release. Robust construction and a reinforced heel area ensure durability against repeated installation and rough use, while the balanced profile helps reduce rider fatigue during extended sessions.
