The John John Techflex (M) fin is a medium sized thruster in the Neutral template category. This is the template that John John Florence rode exclusively to back-to-back World Championships, and as such has become one of the best-selling fins of all time. John’s approach in both waves of consequence and high-performance competition show the versatility of the Techflex construction. Stable and predictable at high speeds, as well as springy and responsive in more playful conditions.
