Duotone Windsurf Fin Race D/LAB (Tuttle)

Just like every product bearing the D/LAB label, the RACE D/LAB fin represents the pinnacle of technology and performance. The high-end design is PWA approved yet it's not ultra technical to sail making it the ideal aftermarket upgrade for any Freerace up to World Cup Slalom board. Designed as Duotone's signature slalom fin for ultimate performance in the most demanding conditions, the RACE D/LAB delivers the lift required to keep your board perfectly balanced even in maxed-out conditions — giving you the speed and control to lead the fleet at that crucial first mark. A balanced design was central to its development, making it equally capable when heading downwind, upwind, or through sharp turns.The construction is based on our Molded Prepreg Technology — the most advanced and most expensive fin construction available. Individually oriented carbon layers guarantee the stiffest possible base combined with a perfectly tuned tip-flex. The RACE D/LAB features the highest carbon content and quality of all our fins resulting in the highest reflex speed for maximum performance. This is premium engineering you can feel the moment you're on the water.That construction standard enabled designer Dani Aeberli to use the thinnest profile of our entire fin range, minimising drag for maximum performance and top-end v-max. A super-stiff base combined with a sophisticated flex pattern — carefully limited to the very tip of the fin — delivers exceptional control while keeping the fin from ever feeling nervous or overly technical to sail. The result is a fin that's genuinely accessible, even on Freerace boards.Going beyond your imagination - the RACE D/LAB sets a new performance benchmark to satisfy both competitive racers and speed-hungry amateurs.
