FUNKTION FUTURE Future compatible MR.TWIN 5.39"3.39" for surfboards Set of 3 FKGFCC-FT-MR-TWIN *This model is a completely new modern keel inspired by the classic keel. The combination of the flex created by the template that gently rakes toward the tip area and the flat foil inside improves reaction and promotes high performance. Funktion Fiber Flex Carbon Composite Fin is molded by mixing 31.3% fiberglass fiber and 6% carbon composite material with nylon material containing UV protection material.The base part has a certain degree of rigidity, and it becomes somewhat soft towards the tip part. Designed with a slow bend. Without increasing the mass (thickness or size), 6% of the total carbon composite material is mixed in to make the flex a little stiffer. In order to create a linear and stable flex characteristic, we use a hybrid material to make it extremely controllable and easy to use for both beginners and advanced users, making it easy to drive even in low-power waves. A high-quality Funktion glass flex fin system that takes advantage of the characteristics of nylon and glass fiber.Among Modex Hawaii test riders and consumers, it provides more drive than PC core fins in waves below head high, and provides freedom of line. It was popular because it had increased power and was also predictable and easy to ride. *The surface of the fin may have a mottled pattern due to the inclusion of carbon composite, but this is due to the characteristics of the material and is not a problem with the product.
