Designed by Malibu legend Greg Liddle, the True Ames L-Flex Single Fin was created to complement the modified displacement hull surfboards he pioneered starting in 1968, using a convex bottom contour to generate trim, speed, and planing power in lower-energy waves. Built to match those hydrodynamic principles, the L-Flex features a thinner precision foil and finely tuned flex that delivers strong down-the-line projection, smooth transitions, and a lively, responsive feel through full rail carves and accelerating sections. Over more than 40 years of refinement, the L-Flex has proven versatile across a wide range of boards designed for speed and flow. Constructed from hand-laid Volan fiberglass with carefully oriented weave and flex that engages through the body rather than only the tip, this fin enhances drive, speed, and projection through turns.

Product Construction
Volan - Solid Fiberglass
Each Volan fin is hand-cut from premium fiberglass and aligned for optimal weave orientation to deliver superior flex and performance. Made in Santa Barbara, CA, these limited-supply fins feature a heavier, denser Volan cloth that increases speed and projection through turns. Each 44-layer panel is laid up by hand for ideal glass-to-resin balance, ensuring strength, consistent flex, and long-lasting “memory” that returns to center after each turn.
Additional Info
Designed by Malibu legend Greg Liddle, the L-Flex fin was originally intended to be paired with the ‘modified displacement hull’ surfboards he became famous for pioneering beginning in 1968. This surfboard design is borrowed from the same hydrodynamic principles in boat hulls–it has a convex bottom contour which enables riders to trim more forward and find plane in waves with less power. And it requires a complimentary fin with a solid, finely-tuned flex. Enter the L-Flex…
Thinner style precision foil with optimal flex
Volan fiberglass construction generates high-performance flex
The 9.0" and 9.5" sizes have a wide (‘W’) option, where the base is a bit longer for added stability
Since its inception, this fin has become a widely popular option for an array of wave riding equipment; it pairs especially well with boards that are designed for acceleration, full rail carves, and smooth transitions. The L-Flex will provide down-the-line projection and positive response through turns, giving your board an energetic and alive feeling.
At True Ames, they are indebted to the invaluable guidance that Greg has provided. It was his clear vision that was a catalyst for Chuck making fins with precision foils, in order to create the perfect amount of power and drive. Now, after more than 40 years of producing the L-Flex, it is still one of their favorite fins they carry. Throw one in your board and feel the difference that four decades of refinement can make!
