Sonar Speed v2 Stabilizer S178 2026

Designed for maximum speed, while providing the pitch stability required for powered riding, the S178v2 is recommended for riders pushing high speeds with faster front wings. Its foil sections are tuned for efficiency in the mid to high-speed range, while the dihedral rondure (front view) provides a more locked-in feel, which can boost confidence when powered up and pushing high speeds and upwind angles. The pre-preg high modulus carbon construction ensures optimal stiffness and direct performance. Thin profile sections reduce drag, while the material properties help maintain structural integrity and rigidity.
