N1 Drive

Base 3.5" wide
Height 2"
Small N1
 
The N1 added to your Quad set-up will increase drive and provide directional control through turns, without causing you to lose speed, flow, or the traditional quad freedom.
The N1 is designed with a single tab that allows the fin to be positioned in the forward and rear center plug to cater for the individual drive requirements of each surfer.
