QD2 4.0 Blackstix 3.0 (Quad Rears) - M

Looking to turn your favourite Thruster set into a Quad? This pair of Blackstix 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, and will favor boards that have the rear boxes set off the rail, closer to the stringer.
