True Ames Derrick Disney RDM Twinzer Fins – Shop Now

The RDM Twinzer is Derrick Disney’s primary twinzer setup for the Midzr, Roe, and Egg models. This set features 70/30 foiled, stout rear fins with a wide base that seamlessly transitions into a fuller drop tip. The canard, working in conjunction with the precise rake and double foil of the rear fin, provides effortless drive and exceptional smoothness through turns.

The RDM’s double foiled canard fin features a wide base and striking curves similar to a Gephart 2 keel fin. This low-profile canard is available in multiple angles to achieve the optimal cant of approximately 13°, perfectly suited to the RDM Twinzer formula.
