Mark Richard's popular 4 x World Title twin template. Highly upright twin, making for an ultra loose feel with fast release. Overview The MR Freeride Twin fin takes us back to a time when Mark was reshaping the way surfers approached the wave. Cut from an old fibreglass skateboard deck, the original freeride fins paired with MR's revolutionary surfboard design changed the direction of surfboard design forever. The Freeride twin sits very upright, making it super loose and free, with plenty of fast release off the top. The tip is more refined compared to his signature twin 1, increasing the ability to pivot and turn on a dime. Board Types Designed to fit the FCS II Fin System. Perfect twin fin for any retro-style board. Recommended for all board types including fish, funboard and twin fin boards. Performance Glass Performance Glass (PG) fins have a rigid, highly responsive flex pattern that’s generally isolated towards the tip of the fin. This construction is widely used by advanced and pro-level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.
