JS SubXero Surfboard in Carbotune Dims: 5’7 x 20 1/4 x 2 5/8 - 32L Fins: FCS 2.0 Construction: Carbotune THE FASTEST BOARD FOR SLOW WAVES. This is everything you want in small surf like in Dubai. To create the Sub Xero, JS created ann ultra-fast low to flat rocker and full outline, but with the nose pulled in a touch, and a wider, straighter tail. The vee in the nose prompts quick rail to rail transitions, moving into a deeper single to double concave, which helps the Sub Xero to hold speed and change directions with minimal energy. It’s designed to be as performance oriented as you could possibly ride in knee high waves. For slow waves, you need the fastest board. ABOUT CARBOTUNE: The benchmark after making Formula 1 style surfboards for 25 years is all about getting the balance of weight and durability into a board that will perform better than ever. JS has used all of that documented data on what is the optimal weight for each number of litres, for each surfer, and the type of surfing that they do. All of that has gone into making sure these CarboTune boards come out at those ideal specs. It’s a finely tuned balance for weight and durability to equal the performance wanted. What the construction comes back to is a relatively simple formula: Weight & Durability = Performance. That’s why it’s taken 6 years – these elements have finally come together with the ideal balance for any surfboard made in CarboTune to both perform and last.
