Balsa Flex

Dive into the High-End Innovations Behind Our Boards: Durability, Performance, and Lightweight Excellence.

Balsa Flex in detail

Balsa Flex is SUNOVA’s original construction from our legendary founder, and pioneer of the parabolic rail - Bert Burger. It is our primary construction for all boards over 8’. Developed over the past 30 years and refined to provide the most unbelievable surfing experience, this technology is not one to look past if you are in the market for a Longboard. A lightweight EPS core is coupled with a ½” parabolic balsa rail that is then sandwiched between balsa skins top and bottom offering a product with unmatched spring and return.

The bottom is a 1.5mm balsa/fiberglass sandwich that is not completely rigid. This softer area on the bottom cushions the ride of the board, making it amazingly unaffected by chatter, giving you a smooth ride even when conditions are bumpy and average. The deck is a 2mm balsa/fiberglass sandwich with mini I beams that connect the glass under the wood, with the glass over. This creates a very rigid strong sandwich structure that is incredibly resistant to compressions, creating a strong and responsive feeling underfoot.

Finished off with solid balsa nose and tail blocks for additional resistance to dings, these boards look even better than they perform. Fitted with a self-regulating air vent that utilizes a slightly permeable Goretex membrane encased in a special aluminum vent designed and engineered by TBF, Balsaflex boards are functional and forward-thinking.

Balsa Flex features

  • 1.0 lb EPS Core

    Lightweight EPS core.

  • 2mm Scored Balsa Sandwich

    2mm of sustainably sourced Scored Balsa wood, encased in bio epoxy resin and fiberglass offering amazing impact and compression resistance. The mini I beam scores connect the layer of glass above the wood to the layer below creating a very resilient structure.

  • Self Regulating Air Vent

    Slightly permeable Gortex membrane that allows air to pass freely, but not water.

  • Carbon Fiber Reinforced Leash Plug

    Carbon Fiber reinforced leash plug for better strength.

  • High Density Foam Reinforced Fin System

    High-density foam reinforced fin systems offer amazing strength and resilience.

  • Parabolic Balsa Rail

    1/2" balsa parabolic rail running the entire outline of the board, offering great flex characteristics.

  • Solid Balsa Nose/Tail Blocks

    Solid Balsa Nose/Tail block for superior impact resistance.
