Fiber Reinforced Plywood – three words describing the common denominator of the TREIBER blade line and moreover the basic characteristic of andro TREIBER Q: a synthetic fiber integrated into the veneer composition increasing the blade’s sweet spot. andro TREIBER Q lives on the impulse given by the so called Q-Fiber placed directly under the outer ply. The Kiri core and Koto outer ply antagonize the hardness of the carbon layer to ensure maximum control and convenient playing feel. TREIBER Q bundles all energy into the stroke. No vibrations, no energy loss!
