Description

The Koalition Keel Quad Fins deliver speed in abundance to your classic quad fin surfboard. This modern template has a large swept back area with a small cutaway at the trailing edge which still allows the board to pivot and turn when required.

Koalition Keel Quadfins are made from fibreglass with a cool smoke tint. These fins will fit the older FCS box or the newer FCS II box (needs grub screws) a brilliant alternative to higher price FCS II or Futures set ups!
