The QD2 4.00 Honeycomb is a medium size quad rear with a Ride Number of 5.3. Looking to turn your favourite 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 favour boards that have the rear boxes set off the rail, closer to the stringer. 

Honeycomb construction gives lightness without compromising on strength or flex.
