In the ongoing quest for lighter, stronger materials for building surfboards, 101 Fin Company is looking to natural resources for it’s fins. Bamboo fins weigh in approximately 50% lighter than most RTM honeycomb fins with a flex memory that rivals or exceeds solid fiberglass fins. The unidirectional nature of wood gives the fin strength and stiffness at the base, while allowing the tip to flex. But the real secret is in the flex memory of the wood itself. Wood fins use less resin and material. Wood fins are nothing new in surfboards but now they are removable. Combined with the Lokbox system that allows 1/2″ adjustment to fine tune your surfing, the performance wood fin revolution has already began.
