QD2 4.15 Flat Foil
Looking to turn your favorite Thruster set into a Quad? This pair of Quad Rears can be combined with any Futures front fins to suit your riding preference, board design and waves. With a symmetrical foil, these rears cater to fluid rail to rail surfing and speed. They will favor boards that have the rear boxes set off the rail, closer to the stringer.
Honeycomb fins have a lightweight hexagonal core which reduces the weight and maintains the flex properties. These fins are engineered with a medium flex pattern, making them stiffer than Blackstix but more flexible than fiberglass. These fins have a Ride Number range of 4-7 and are great all around fins for any condition.
