The Asymmetric Incinerator front fins! More power, more drive, more speed, less drag. These are something special! Made from our ‘super stiff’ material the A.I’s are much like the rest of the Incinerator range – slim, high aspect and fast. The A.I. fin has a similar template to the Incinerator front but with a slightly wider chord to accommodate the 30/70 foil.  The A.I's are optimised for quad set ups. Choose the degree depending on your boards box angles - 2º for straight boxes, 1º for toed in boxes. They also work exceptionally well in thrusters with a little more toe angle selected.
