Bionic Flex Design (BFD)

The kite surfboard of our dreams should feel like a traditional polyester board – light as a feather with natural flex. Unfortunately, not even bi-laminate polyboards withstand the high and continuous stress of kitesurfing. They get deep bumps on the deck, dents along the rails, and finally break, usually right when we have fallen in love with the board. Bringing this tale of woe to an end was our motivation and the solution was BFD, the Bionic Flex Design. BFD boards conserve polyboard-like flex but remain incredibly robust due to the bionic core construction and the strong bonding with the laminate.
The core construction profits from Mother Earth’s wisdom. More precisely, it adopts the bamboo principle where strength, flex, and resistance are realized by geometric alignment of hollow compartments within the core. Application of this bionic doctrine enabled us to reduce material input and increase the flex without compromising surfboard robustness.
To conserve the BFD core, it is glassed with special fiber sheets which form a tough exoskeleton. Glass sheets are pressed onto the core with a “double-vacuum” technique and are subsequently hardened at high temperatures. This procedure guarantees maximal bonding between laminate and core which will heal your heart-ache from broken polyboard-relationships.
Crêpe Construction (CrêCo)
A proper French crêpe is very thin and super tasty! Inspired by this culinary characteristic, DSP shaper Andreas realized that these principles should also be applicable for kitesurfboards and developed the “Crêpe construction”. These two properties provide CrêCo boards with unbelievable flex. They effortlessly absorb hard impacts, buffer vibrations, and glide through chop like a Mercedes S-class. Furthermore, CrêCo boards will deliver additional feedback thereby strongly supporting your ability to interpret the wave – something which is particularly valuable for wave beginners. However, experienced riders should also take a closer look at CrêCo boards as their reduced thickness will also reduce their weight. We noticed that light weight in combination with the flat deck and CrêCo flex are ideal to learn strapless aerials because the board hangs nicely on your feet and the extra flex facilitates landings.
So which conditions work well for CrêCo boards? The smooth tuning of these boards makes them ideal companions for choppy conditions in the every-day Baltic Sea. Beginners and people with sensitive joints will definitely love this.
