Power Box Fin M88 Supersport 31cm Select SML07520031

Power Box Fin M88 Supersport 31cm Select SML07520031

Description:

The Select M88 Supersport SL is a high-performance freeride/freerace power box fin engineered for speed, control and responsiveness. Constructed from high‑modulus carbon, it features an ultra‑thin profile (8.8% thickness — 8.8 mm at a 10 cm chord) and a double‑curved outline that delivers exceptional maneuverability with minimal drag. Select’s Active Flex Technology balances a stiff trailing edge with a dynamically responsive leading edge to produce very vertical lift and reduced hull wetted surface at high speeds. The result is precise tracking, rapid acceleration and stable top‑end performance while remaining forgiving enough for advanced amateurs. Designed for use on freeride and freerace boards (85–150 L), the M88 Supersport boosts race and freeride performance without sacrificing control. It is made to install in Power Box style fin systems and holds up to demanding use thanks to its high‑modulus carbon construction.

• High‑modulus carbon construction for light weight, stiffness and durability
• Ultra‑thin profile (8.8% thickness) to minimize drag and maximize speed
• Active Flex Technology: rigid trailing edge with a compliant leading edge for controlled twist and vertical lift
