Shapers SPINE-TEK® is precision engineered utilising a unique composition of fibres and resin that aligns with the principles of elastic energy. The composition of Shapers SPINE-TEK® has been designed to have a chemical structure that bonds with existing manufacturing materials and resins, helping to make stronger boards that will have a longer life span with increased value.
An important feature of SPINE-TEK® is that it does not fail under the normal stresses of surfing. This is a distinct benefit over timber stringers and even carbon, which absorb a certain amount of force before over loading and potentially failing (cracking, snapping, etc).
Shapers SPINE-TEK® will also maintain a constant memory, returning back to its natural shape (which is the natural shape of the surfboard).
Shapers SPINE-TEK® governs the way in which a board flexes and responds. There are two main flex classifications that define a surfboards performance: longitudinal (vertical: nose to tail) and torsional (horizontal: rail to rail ). These flex characteristics determine the responsiveness of the surfboard and are an integral part of surfboard design and construction.
There is a delicate balance between stiffness and flex depending on the desired outcome. A surfboard flexing in unity with the surfer and the wave is beneficial, for example, holding speed whilst going straight (minimal flex – minimising friction) and then flexing with responsiveness when performing manoeuvres.
Tailoring flex patterns to suit different surfing styles, wave conditions and weights optimises performance and will therefore drive the future of surfboard design.
