Power Flex is a Pro Teck Fin with a medium core flex. The fin bends on turns, and then springs back, creating forward thrust similar to a swim fin. The medium flex core and flexible trailing edge makes the board turn smooth and fluid, with continuous speed.
Power Flex Fins are recommended for intermediate to professional surfers.
Very nice fins! Beautiful and of very good quality. I use "Power Flex Fins" on my two boards.
This fin is delivered with two screws for US box and their nuts. Fine!
Came on time with no fuss and was exactly the piece I needed
