The Flying Diamonds Bing Flex Single Fin draws inspiration from classic flex fins and delivers the most versatile range of performance across our range. Small size works great in mid-length singles and larger sizes for traditional logs of any tail shape. The base is substantial, providing plenty of drive off the bottom and the tapered tip provides just the right amount of flex to add projection out of turns. Its moderate foil keeps it fast down the line while providing enough hold when on the nose. This fin takes full advantage of the flex characteristics of its Volan lamination.
