The Spike Concept Blue, listed as Spike CB in the catalogue, is Duotone's lower-impact light-wind twin tip. It shares the large surface area, flat rocker and upwind emphasis of the Spike family but replaces the SLS model's carbon and Innegra laminate with Flax and Basalt fibres. The board is intended for riders who want early planing and efficient marginal-wind cruising while retaining enough response for carving, small jumps and straightforward tricks.
Concept Blue Construction
Flax fibre is used for dampening, comfort and reduced reliance on conventional glass reinforcement. Basalt fibre adds stiffness and a lively response so the large board does not feel excessively flexible under load. Duotone describes the material package as a more sustainable construction intended to lower product impact without abandoning performance. The associated Concept Blue approach also uses solar energy during board production.
Light-Wind Platform
A large area underfoot supports easy water starts and early planing, allowing the board to generate lift and maintain momentum in minimal power. The flat rocker reduces drag and keeps the base efficient at lower speeds. A revised outline is designed to carve more smoothly and give better directional control than a simple rectangular light-wind board. These elements help the rider remain on the plane through lulls and make productive use of a larger kite's pull.
Rails, Flex and Handling
Angled rails provide heel-side grip and support upwind progress, helping the board resist sideways slip when the wind is marginal. They also add a more decisive edge release for jumps. Medium flex balances stability with everyday comfort and gives the tips enough movement to absorb surface disturbance. Basalt reinforcement keeps the response clear, while Flax dampening reduces harshness in chop. The board is therefore intended to cruise efficiently without feeling entirely rigid or one-dimensional.
Sizes and Specifications
The Spike Concept Blue is available in 153 x 46.5 cm and 164 x 47.5 cm. Duotone lists both sizes for riders above 40 kg, with selection depending on wind, rider size and desired low-end support. Both use FS 5.0 Glass 50 fins. Published board weights are approximately 3.55 kg and 3.77 kg, with a stated manufacturing tolerance of plus or minus five per cent. The weights are slightly higher than the corresponding SLS boards, reflecting the different material package.
Riding Character
The board focuses on getting onto the water early, accelerating cleanly and making reliable upwind progress. Its rail shape and Basalt response provide enough feedback for transitions and modest freestyle, while the broad base and medium flex preserve stability. It is a specialist light-wind board rather than an all-condition twin tip, but its smoother carving and responsive construction are intended to make marginal sessions more engaging.
Summary
The Spike Concept Blue is a large, efficient light-wind twin tip using Flax and Basalt fibres. A flat rocker, wide surface, revised outline, angled rails and medium flex support easy starts, early planing, upwind control and comfortable cruising. It suits riders seeking the Spike's session-saving low end through Duotone's more sustainable construction route.
