AU 24K Grom (Full Base)



The AU 24K Grom thruster offers a reinforced blend of carbon fiber in the lower half of the fin that deflects energy from the solid base to the flexible tip. This energy has a recoil effect when combined with our patented AU signature curve! It creates what we refer to as "Spiral Propulsion Technology". This fin set is traditionally ridden by a lighter weight performance shortboard surfer but can also be utilized as side-bite fins on a 2-1 longboard or SUP set-up!
