Pick up these Futures Fins HS 4.20 Generation Quad Rears to complement your existing tri-fin set and give yourself the ability to swap between a thruster and a quad fin configuration. You'll be able to adapt your board to the days conditions and explore new characteristics of your surfboards capabilities. Sitting one notch below the Blackstix on the Ride Number scale, all Generation Series fins hold Ride Numbers between 9 to 7, for those of you looking for a bit more stability and drive than Blackstix.

To control tip flex dynamics, Futures has uniquely oriented multiple layers of uni-directional fiberglass. The uni-fiberglass has more spring then normal bi-directional glass and it is woven with strands of poly-fibers that create more strength and control in the fin tip. In addition uni-directional carbon strips have been placed vertically across the front half of each fin. Acting as spines, this secures the leading edge and forces the tip to flex across less area and becoming much "snappier". Additional strength in the right places allow the Generation Series to remain lightweight and strong.

To add one more layer of performance to the Generation Series, Futures uses epoxy resin. Epoxy resin is lighter and more resilient than polyester resin. These features all play a role in making the Generation Series a responsive, speed-generating fin, while retaining an element of control. Bi-directional 12K carbon panels cover the base on the inside and outside of the fin. This solid base creates drive and leave the tip free to remain resilient. The combination is lightweight ad stable, giving you both speed and power.


Generation fins combine the perfect blend of unique carbon & fiberglass layups to provide all the speed you need while maintaining an element of control.

80:20 Foil

The 80:20 Foil is a balance between a flat and symmetrical foil. This allows you to get vertical on the face of the wave and hold you through a drawn out bottom turn.

Futures Fins HS 4.20 Generation Quad Rears - Carbon/Smoke Good all aroundersReview by Water Water
Have only used once and not a "Quad guy", but wanted to play around fin set ups since board has 5 fin boxes. Used in waist/stomach beach break for a couple hours. Seem to have good hold and speed but does not make board too tracky.

I'm 5'11", 175 lbs, used with Future Roberts Gen large for front fins on 6' Pyzel Phantom.
