Talk to a REAL Pro who rides it.
Located in Cape Hatteras. No bots.MR's twin + stabiliser template delivers exceptional pivot off the top, while the centre fin adds control. Built in Performance Core construction and designed in the two-tab FCS I base, the MR Twin + 1 is a modern take on Mark Richards' legendary fin template.
Renowned for speed and drive, the MR Twin template is designed for fast acceleration and fluid rail-to-rail transitions. The small centre stabiliser fin enhances control and hold without compromising the freedom and manoeuvrability of a twin fin setup.
With a flat foil and neutral sweep, this fin balances pivot, release, and control across a wide range of conditions.
Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer maintain drive and hold through a turn. This versatile fin material is light and can be used in a variety of different conditions.
