Balsa is an exceptionally light hardwood. Laminated vertically together divided by strips of woven flax (also known as linseed), to provide additional torsional and compression strength. Lighter than Poplar/Ash but more expensive.
Paulownia is a very light hardwood that is stable and easy to machine. Cores made with this material are lighter than Balsa/Flax cores, but are more expensive and require a lamination layer such as carbon-fibre to improve responsiveness.
STP Technology is a patent-pending process used to press a small wave into the length of the ski. This creates a ‘pre-stressed’ core with increased torsional strength, letting us use less wood to create lighter, more forgiving skis with above-average edge-grip. For 14/15, we have developed a variation of the technique that provides a perfectly flat base.
